Abstract
Repetitive exposure to antigen in chronic infection and cancer drives T cell exhaustion, limiting adaptive immunity. In contrast, aberrant, sustained T cell responses can persist over decades in human allergic disease. To understand these divergent outcomes, we employed bioinformatic, immunophenotyping and functional approaches with human diseased tissues, identifying an abundant population of type 2 helper T (TH2) cells with co-expression of TCF7 and LEF1, and features of chronic activation. These cells, which we termed TH2-multipotent progenitors (TH2-MPP) could self-renew and differentiate into cytokine-producing effector cells, regulatory T (Treg) cells and follicular helper T (TFH) cells. Single-cell T-cell-receptor lineage tracing confirmed lineage relationships between TH2-MPP, TH2 effectors, Treg cells and TFH cells. TH2-MPP persisted despite in vivo IL-4 receptor blockade, while thymic stromal lymphopoietin (TSLP) drove selective expansion of progenitor cells and rendered them insensitive to glucocorticoid-induced apoptosis in vitro. Together, our data identify TH2-MPP as an aberrant T cell population with the potential to sustain type 2 inflammation and support the paradigm that chronic T cell responses can be coordinated over time by progenitor cells.

Abstract
BACKGROUND IgE-induced mast cell (MC) degranulation can be inhibited by IgG antibodies, signaling via FcγRIIb, but the effects of IgG on IgE-induced MC transcription are unknown. OBJECTIVE We sought to assess inhibitory IgG:FcγRIIb effects on MC responses to IgE using complementary transcriptomic and functional approaches. METHODS RNA sequencing was performed on bone marrow-derived MCs from wild-type and FcγRIIb-deficient mice to identify genes activated following IgE receptor crosslinking that were further modulated in the presence of antigen-specific IgG in an FcγRIIb-dependent fashion. Parallel analyses of signaling pathways and allergic responses in vivo were performed to assess the impact of these changes in gene expression. RESULTS Rapid changes in the transcription of 879 genes occurred in MCs activated by IgE, peaking at 1 hour. Surprisingly, only 12% of these were altered by IgG signaling via FcγRIIb, including numerous transcripts involved in orchestrating type 2 responses linked to spleen tyrosine kinase signaling. Consistent with this finding, IgG suppressed IgE-induced phospho-intermediates in the spleen tyrosine kinase signaling pathway. In vivo studies confirmed that the IgG-mediated suppression of both systemic anaphylaxis and MC-driven tissue recruitment of inflammatory cells following allergen challenge was dependent on FcγRIIb. In contrast, genes in the STAT5a cell survival pathway were unaltered by IgG, and STAT5a phosphorylation increased after IgE-induced MC activation but was unaffected by IgG. CONCLUSIONS Our findings indicate that inhibitory IgG:FcγRIIb signals block an IgE-induced proallergic program but spare a prosurvival program.

Abstract
Mast cells (MCs) are widely recognized as central effector cells during type 2 inflammatory reactions and thought to also play a role in innate immune responses, wound healing, and potentially cancer. Circulating progenitor cells mature to MCs in peripheral tissues, where they exhibit phenotypic and functional heterogeneity. This diversity likely originates from differences in MC development imprinted by microenvironmental signals. The advent of single-cell transcriptomics reveals MC diversity beyond differences in proteases that were classically used to identify MC phenotypes. Here, we provide an overview of the current knowledge on MC progenitor differentiation and characteristics, and MC heterogeneity seen in health versus disease, that are drastically advanced through single-cell profiling technologies. This powerful approach can provide detailed cellular maps of tissues to decipher the complex cellular functions and interactions that may lead to identifying candidate factors to target in therapies.

Abstract
Mast cells are heterogeneous, tissue-resident immune effector cells widely recognized to play pathobiologic roles in the development of mucosal type 2 inflammation. While mast cell progenitors can be found in peripheral blood, phenotypically mature mast cells can only be found within peripheral tissues. Here, we describe optimized tissue digestion protocols for obtaining mast cells from the murine lung and from human sinus tissue. Following tissue digestion, mast cells can be identified and sorted by flow cytometry using antibodies against defined surface markers. We also provide protocol for intracellular protease immunostaining, allowing for further characterization of mast cells.

Abstract
BACKGROUND Eosinophilic asthma and nasal polyposis are hallmarks of aspirin-exacerbated respiratory disease (AERD), and IL-5 inhibition has been shown to provide therapeutic benefit. However, IL-5Rα is expressed on many cells in addition to eosinophils, and the mechanisms by which IL-5 inhibition leads to clinical benefit in eosinophilic asthma and nasal polyposis are unlikely to be due exclusively to antieosinophil effects. OBJECTIVE We sought to identify the mechanisms by which anti-IL-5 treatment with mepolizumab improves respiratory inflammation in AERD. METHODS The clinical characteristics, circulating granulocytes, nasal scraping transcripts, eosinophilic cationic protein, tryptase, and antibody levels, and urinary and nasal eicosanoid levels were measured for 18 subjects with AERD who were taking mepolizumab and compared with those of 18 matched subjects with AERD who were not taking mepolizumab. RESULTS Subjects taking mepolizumab had significantly fewer peripheral blood eosinophils and basophils, and those cells that remained had higher surface CRTH2 expression than did the cells from subjects not taking mepolizumab. Nasal prostaglandin F2α, prostaglandin D2 metabolites, leukotriene B4, and thromboxane levels were lower in subjects taking mepolizumab, as were urinary levels of tetranor-prostaglandin D2 and leukotriene E4. The nasal epithelial cell transcripts that were overexpressed among subjects with AERD who were taking mepolizumab were enriched for genes involved in tight junction formation and cilium organization. Nasal and urinary prostaglandin E2, tryptase, and antibody levels were not different between the 2 groups. CONCLUSION IL-5 inhibition in AERD decreases production of inflammatory eicosanoids and upregulates tight junction-associated nasal epithelial cell transcripts, likely due to decreased IL-5 signaling on tissue mast cells, eosinophils, and epithelial cells. These direct effects on multiple relevant immune cells contribute to the mechanism of benefit afforded by mepolizumab.

Abstract
The American Initiative in Mast Cell Diseases (AIM) held its inaugural investigator conference at Stanford University School of Medicine in May 2019. The overarching goal of this meeting was to establish a Pan-American organization of physicians and scientists with multidisciplinary expertise in mast cell disease. To serve this unmet need, AIM envisions a network where basic, translational, and clinical researchers could establish collaborations with both academia and biopharma to support the development of new diagnostic methods, enhanced understanding of the biology of mast cells in human health and disease, and the testing of novel therapies. In these AIM proceedings, we highlight selected topics relevant to mast cell biology and provide updates regarding the recently described hereditary alpha-tryptasemia. In addition, we discuss the evaluation and treatment of mast cell activation (syndromes), allergy and anaphylaxis in mast cell disorders, and the clinical and biologic heterogeneity of the more indolent forms of mastocytosis. Because mast cell disorders are relatively rare, AIM hopes to achieve a coordination of scientific efforts not only in the Americas but also in Europe by collaborating with the well-established European Competence Network on Mastocytosis.

Abstract
Mast cells (MCs) play a pathobiologic role in type 2 (T2) allergic inflammatory diseases of the airway, including asthma and chronic rhinosinusitis with nasal polyposis (CRSwNP). Distinct MC subsets infiltrate the airway mucosa in T2 disease, including subepithelial MCs expressing the proteases tryptase and chymase (MCTC) and epithelial MCs expressing tryptase without chymase (MCT). However, mechanisms underlying MC expansion and the transcriptional programs underlying their heterogeneity are poorly understood. Here, we use flow cytometry and single-cell RNA-sequencing (scRNA-seq) to conduct a comprehensive analysis of human MC hyperplasia in CRSwNP, a T2 cytokine-mediated inflammatory disease. We link discrete cell surface phenotypes to the distinct transcriptomes of CRSwNP MCT and MCTC, which represent polarized ends of a transcriptional gradient of nasal polyp MCs. We find a subepithelial population of CD38highCD117high MCs that is markedly expanded during T2 inflammation. These CD38highCD117high MCs exhibit an intermediate phenotype relative to the expanded MCT and MCTC subsets. CD38highCD117high MCs are distinct from circulating MC progenitors and are enriched for proliferation, which is markedly increased in CRSwNP patients with aspirin-exacerbated respiratory disease, a severe disease subset characterized by increased MC burden and elevated MC activation. We observe that MCs expressing a polyp MCT-like effector program are also found within the lung during fibrotic diseases and asthma, and further identify marked differences between MCTC in nasal polyps and skin. These results indicate that MCs display distinct inflammation-associated effector programs and suggest that in situ MC proliferation is a major component of MC hyperplasia in human T2 inflammation.

Abstract
Murine mast cells (MCs) contain two lineages: inducible bone marrow-derived mucosal MCs (MMCs) and constitutive embryonic-derived connective tissue MCs (CTMCs). Here, we use RNA sequencing, flow cytometry, and genetic deletion in two allergic lung inflammation models to define these two lineages. We found that inducible MCs, marked by β7 integrin expression, are highly distinct from airway CTMCs at rest and during inflammation and unaffected by targeted CTMC deletion. β7High MCs expand and mature during lung inflammation as part of a TGF-β-inducible transcriptional program that includes the MMC-associated proteases Mcpt1 and Mcpt2, the basophil-associated protease Mcpt8, granule components, and the epithelial-binding αE integrin. In vitro studies using bone marrow-derived MCs (BMMCs) identified a requirement for SCF in this this TGF-β-mediated development and found that epithelial cells directly elicit TGF-β-dependent BMMC up-regulation of mMCP-1 and αE integrin. Thus, our findings characterize the expansion of a distinct inducible MC subset in C57BL/6 mice and highlight the potential for epithelium to direct MMC development.

Abstract
There is pressing urgency to understand the pathogenesis of the severe acute respiratory syndrome coronavirus clade 2 (SARS-CoV-2), which causes the disease COVID-19. SARS-CoV-2 spike (S) protein binds angiotensin-converting enzyme 2 (ACE2), and in concert with host proteases, principally transmembrane serine protease 2 (TMPRSS2), promotes cellular entry. The cell subsets targeted by SARS-CoV-2 in host tissues and the factors that regulate ACE2 expression remain unknown. Here, we leverage human, non-human primate, and mouse single-cell RNA-sequencing (scRNA-seq) datasets across health and disease to uncover putative targets of SARS-CoV-2 among tissue-resident cell subsets. We identify ACE2 and TMPRSS2 co-expressing cells within lung type II pneumocytes, ileal absorptive enterocytes, and nasal goblet secretory cells. Strikingly, we discovered that ACE2 is a human interferon-stimulated gene (ISG) in vitro using airway epithelial cells and extend our findings to in vivo viral infections. Our data suggest that SARS-CoV-2 could exploit species-specific interferon-driven upregulation of ACE2, a tissue-protective mediator during lung injury, to enhance infection.

Abstract
BACKGROUND The cause of severe nasal polyposis in aspirin-exacerbated respiratory disease (AERD) is unknown. Elevated antibody levels have been associated with disease severity in nasal polyps, but upstream drivers of local antibody production in nasal polyps are undetermined. OBJECTIVE We sought to identify upstream drivers and phenotypic properties of local antibody-expressing cells in nasal polyps from subjects with AERD. METHODS Sinus tissue was obtained from subjects with AERD, chronic rhinosinusitis (CRS) with nasal polyps (CRSwNP), CRS without nasal polyps, and controls without CRS. Tissue antibody levels were quantified via ELISA and immunohistochemistry and were correlated with disease severity. Antibody-expressing cells were profiled with single-cell RNA sequencing, flow cytometry, and immunofluorescence, with IL-5Rα function determined through IL-5 stimulation and subsequent RNA sequencing and quantitative PCR. RESULTS Tissue IgE and IgG4 levels were elevated in AERD compared with in controls (P < .01 for IgE and P < .001 for IgG4 vs CRSwNP). Subjects with AERD whose nasal polyps recurred rapidly had higher IgE levels than did subjects with AERD, with slower regrowth (P = .005). Single-cell RNA sequencing revealed increased IL5RA, IGHG4, and IGHE in antibody-expressing cells from patients with AERD compared with antibody-expressing cells from patients with CRSwNP. There were more IL-5Rα+ plasma cells in the polyp tissue from those with AERD than in polyp tissue from those with CRSwNP (P = .026). IL-5 stimulation of plasma cells in vitro induced changes in a distinct set of transcripts. CONCLUSIONS Our study identifies an increase in antibody-expressing cells in AERD defined by transcript enrichment of IL5RA and IGHG4 or IGHE, with confirmed surface expression of IL-5Rα and functional IL-5 signaling. Tissue IgE and IgG4 levels are elevated in AERD, and higher IgE levels are associated with faster nasal polyp regrowth. Our findings suggest a role for IL-5Rα+ antibody-expressing cells in facilitating local antibody production and severe nasal polyps in AERD.

Abstract
Respiratory epithelial cells (EpCs) orchestrate airway mucosal inflammation in response to diverse environmental stimuli, but how distinct EpC programs are regulated remains poorly understood. Here, we report that inhalation of aeroallergens leads to expansion of airway brush cells (BrCs), specialized chemosensory EpCs and the dominant epithelial source of interleukin-25 (IL-25). BrC expansion was attenuated in mice lacking either LTC4 synthase, the biosynthetic enzyme required for cysteinyl leukotriene (CysLT) generation, or the EpC receptor for leukotriene E4 (LTE4), CysLT3R. LTE4 inhalation was sufficient to elicit CysLT3R-dependent BrC expansion in the murine airway through an IL-25-dependent but STAT6-independent signaling pathway. Last, blockade of IL-25 attenuated both aeroallergen and LTE4-elicited CysLT3R-dependent type 2 lung inflammation. These results demonstrate that CysLT3R senses the endogenously generated lipid ligand LTE4 and regulates airway BrC number and function.

Abstract
Abstract
Mast Cells (MCs) infiltrate the nasal polyps of patients with chronic rhinosinusitis (CRS) and the bronchial mucosa of patients with mild, moderate, and severe asthma. MCs are a significant source of IL-33-elicited Th2 cytokines in the sputum of asthmatics and upon activation generate or release high levels of mediators including tryptase, histamine, and prostaglandin D2. Although airway MC heterogeneity can readily identified through protease immunostaining and tissue sub-localization, the functional distinctions and developmental relationships between MC subsets remain uncertain, in part because of the lack of flow cytometric markers to distinguish them and technical difficulties in isolating MCs. Using a novel flow cytometric approach we have identified several distinct MC subsets in the nasal polyps of patients with CRS that vary in expression of FcER1, c-kit, B7, CD203 and chymase. Nasal polyp MCs were further characterized through unbiased single cell RNA sequencing, revealing heterogeneity within the MC population and providing novel insight into transcriptional differences between these subsets.

Abstract
Car enzyme inhibition prevents mast cell responses and inflammation following Trichinella spiralis infection or the induction of food allergy–like disease. Type 2 cytokine responses are necessary for the development of protective immunity to helminth parasites but also cause the inflammation associated with allergies and asthma. Recent studies have found that peripheral hematopoietic progenitor cells contribute to type 2 cytokine–mediated inflammation through their enhanced ability to develop into mast cells. In this study, we show that carbonic anhydrase (Car) enzymes are up-regulated in type 2–associated progenitor cells and demonstrate that Car enzyme inhibition is sufficient to prevent mouse mast cell responses and inflammation after Trichinella spiralis infection or the induction of food allergy–like disease. Further, we used CRISPR/Cas9 technology and illustrate that genetically editing Car1 is sufficient to selectively reduce mast cell development. Finally, we demonstrate that Car enzymes can be targeted to prevent human mast cell development. Collectively, these experiments identify a previously unrecognized role for Car enzymes in regulating mast cell lineage commitment and suggest that Car enzyme inhibitors may possess therapeutic potential that can be used to treat mast cell–mediated inflammation.

Abstract
In contrast to resident constitutive mast cells (CMCs), mucosal MCs (MMCs) appear in the lung and trachea of sensitized mice only following inhalation challenge. We monitored the influx and maturation of MCs by their expression of Kit, FcɛRI, β7-integrin and side scatter (SSC) by flow cytometry. Influx of MC progenitors (MCps) (FcɛRI(lo), Kit(int), β7(hi), and SSC(lo)) peaks 1 day after challenges and subsides to baseline by day 7 after challenge. The mature MMCs appear as a distinct population on day 7 and peak at day 14 with higher SSC and FcɛRI expression, but lower β7 and Kit expression. A distinct transitional population is present between 1 and 7 days after challenge. Maturation occurs more rapidly in the trachea. The resident tracheal CMCs had higher SSC, FcɛRI, and Kit and lower β7-integrin expression than the MMCs. By histology, the MMCs follow similar kinetics to the flow cytometry-identified mature MMCs and are notably persistent for >42 days. Steroid treatment reduced inflammation and MCp influx but had no effect on established MMCs. Thus, changes in SSC, FcɛRI, and Kit together with the expression of αE/α4:β7-integrins characterizes the development of induced MMCs from MCps and distinguishes them from resident CMCs in the trachea and large airways.

Abstract
Papain, a cysteine protease allergen with inherent adjuvant activity, induces potent IL-4 expression by T cells in the popliteal lymph nodes of mice following footpad immunization. In this study, we identify a novel, non-BCR-mediated capacity for B cells to rapidly bind and internalize papain. B cells subsequently regulate the adaptive immune response by enhancing ICOS expression on CD4(+) T cells and amplifying Th2 and follicular helper T cell induction. Ab blockade of ICOS ligand, expressed by popliteal lymph node B cells, but not dendritic cells, at the peak of the response inhibits IL-4 responses in wild-type mice but not B cell-deficient mice. Thus, B cells play a critical role in amplifying adjuvant-dependent Th2 polarization following noncanonical acquisition and internalization of the cysteine protease papain.

Abstract
The butyrate-oxidizing, proton-reducing, obligately anaerobic bacterium NSF-2 was grown in batch cocultures with either the hydrogen-oxidizing bacterium Methanospirillum hungatei PM-1 or Desulfovibrio sp. strain PS-1. Metabolism of butyrate occurred in two phases. The first phase exhibited exponential growth kinetics (phase a) and had a doubling time of 10 h. This value was independent of whether NSF-2 was cultured with a methanogen or a sulfate reducer and likely represents the maximum specific growth rate of NSF-2. This exponential growth phase was followed by a second phase with a nearly constant rate of degradation (phase b) which dominated the time course of butyrate degradation. The specific activity of H(2) uptake by the hydrogen-oxidizing bacterium controlled the bioenergetic conditions of metabolism in phase b. During this phase both the Gibbs free energy (DeltaG') and the butyrate degradation rate (v) were greater for NSF-2-Desulfovibrio sp. strain PS-1 (DeltaG' = -17.0 kJ/mol; v = 0.20 mM/h) than for NSF-2-M. hungatei PM-1 (DeltaG' = -3.8 kJ/mol, v = 0.12 mM/h). The DeltaG' value remained stable and characteristic of the two hydrogen oxidizers during phase b. The stable DeltaG' resulted from the close coupling of the rates of butyrate and H(2) oxidation. The addition of 2-bromoethanesulfonate to a NSF-2-methanogen coculture resulted in the total inhibition of butyrate degradation; the inhibition was relieved when Desulfovibrio sp. strain PS-1 was added as a new H(2) sink. When the specific activity of H(2) consumption was increased by adding higher densities of the Desulfovibrio sp. to 2-bromoethanesulfonate-inhibited NSF-2-methanogen cocultures, lower H(2) pool sizes and higher rates of butyrate degradation resulted. Thus, it is the kinetic parameters of H(2) consumption, not the type of H(2) consumer per se, that establishes the thermodynamic conditions which in turn control the rate of fatty acid degradation. The bioenergetic homeostasis we observed in phase b was a result of the kinetics of the coculture members and the feedback inhibition by hydrogen which prevents butyrate degradation rates from reaching their theoretical V(max).

Abstract
The competition between sulfate-reducing and methanogenic bacteria for hydrogen was investigated in eutrophic lake sediments that contained low in situ sulfate concentrations and in sulfate-amended sediments. Sulfate reduction and methane production coexisted in situ in lake surface sediments (0 to 2 cm), but methane production was the dominant terminal process. Addition of 10 to 20 mM sulfate to sediments resulted in a decrease in the hydrogen partial pressure and a concomitant inhibition of methane production over time. Molybdate inhibition of sulfate reduction in sulfate-amended sediments was followed by an increase in the hydrogen partial pressure and the methane production rate to values comparable to those in sediments not amended with sulfate. The sulfate reducer population had a half-saturation constant for hydrogen uptake of 141 pascals versus 597 pascals for the methanogen population. Thus, when sulfate was not limiting, the lower half-saturation constant of sulfate reducers enabled them to inhibit methane production by lowering the hydrogen partial pressure below levels that methanogens could effectively utilize. However, methanogens coexisted with sulfate reducers in the presence of sulfate, and the outcome of competition at any time was a function of the rate of hydrogen production, the relative population sizes, and sulfate availability.

Abstract
Filters incorporating the principles of biological accumulation have been used in Europe to remove iron from drinking water for many years. The authors of this study hypothesized that a modified biological iron-removing filter could simultaneously degrade polycyclic aromatic hydrocarbons (PAHs) in groundwater impacted by former manufactured gas plant (MGP) operations. The MGP-impacted groundwater obtained for this study had an average total iron concentration of 3.8 mg/L and an average total dissolved PAH concentration of 3.0 mg/L. Naphthalene was the primary PAH, with an average concentration of 2.8 mg/L. The groundwater was passed intermittently through duplicate gravel-media columns at 15 to 30 cm/d for 2 months while filtered air was delivered countercurrently at 4 mL/min. The columns remained partially saturated throughout the study. Flooding, which would have indicated plugging of the columns, was not observed, and the pressure needed to aerate the columns remained constant. Total iron in the effluent was below the detection limit of 0.1 mg/L (97% removal) for 40 days of operation. Removal of total PAHs, primarily two- and three-ring compounds, averaged 99%. This single-stage treatment process represents an economical alternative to biological treatment systems currently available for MGP-impacted groundwater that require pretreatment to remove iron.

Abstract
Pseudomonas pseudoalcaligenes POB310 contains genes that encode phenoxybenzoate dioxygenase. The enzyme transforms mono- and dichlorinated phenoxybenzoates to yield protocatechuate that is used as a growth substrate and chlorophenols that are nonmetabolizable. Mass spectral analysis of (18)O metabolites obtained from the protocatechuate 3,4-dioxygenase-deficient mutant, POB310-B1, suggested that the reaction mechanism is a regioselective angular dioxygenation. A cloning vector containing reaction relevant genes (pD30.9) was transferred into Pseudomonas sp. strain B13 containing a modified ortho-cleavage pathway for aromatic compounds. The resultant Pseudomonas sp. strain B13-D5 (pD30.9) completely metabolized 3-(4-chlorophenoxy)benzoate. During growth on 3-phenoxybenzoate, strain B13-D5 (pD30.9) (K(s) = 0.70+/-0.04 mM, mu(max) = 0.45+/-0.03 h(-1), t(d) = 1.5 h, Y = 0.45+/-0.03 g bio- mass x g substrate(-1)) was better adapted to low substrate concentrations, had a faster rate of growth, and a greater yield than POB310 (K(s) = 1.13+/-0.06 mM, mu(max) = 0.31+/-0.02 h(-1), t(d) = 2.2 h, Y = 0.39+/-0.02 g biomass. g substrate(-1)).

Abstract
Pseudomonas pseudoalcaligenes POB310(pPOB) and Pseudomonas sp. strains B13-D5(pD30.9) and B13-ST1(pPOB) were introduced into soil microcosms containing 3-phenoxybenzoic acid (3-POB) in order to evaluate and compare bacterial survival, degradation of 3-POB, and transfer of plasmids to a recipient bacterium. Strain POB310 was isolated for its ability to use 3-POB as a growth substrate; degradation is initiated by POB-dioxygenase, an enzyme encoded on pPOB. Strain B13-D5 contains pD30.9, a cloning vector harboring the genes encoding POB-dioxygenase; strain B13-ST1 contains pPOB. Degradation of 3-POB in soil by strain POB310 was incomplete, and bacterial densities decreased even under the most favorable conditions (100 ppm of 3-POB, supplementation with P and N, and soil water-holding capacity of 90%). Strains B13-D5 and B13-ST1 degraded 3-POB (10 to 100 ppm) to concentrations of <50 ppb with concomitant increases in density from 10(6) to 10(8) CFU/g (dry weight) of soil. Thus, in contrast to strain POB310, the modified strains had the following two features that are important for in situ bioremediation: survival in soil and growth concurrent with removal of an environmental contaminant. Strains B13-D5 and B13-ST1 also completely degraded 3-POB when the inoculum was only 30 CFU/g (dry weight) of soil. This suggests that in situ bioremediation may be effected, in some cases, with low densities of introduced bacteria. In pure culture, transfer of pPOB from strains POB310 and B13-ST1 to Pseudomonas sp. strain B13 occurred at frequencies of 5 x 10(-7) and 10(-1) transconjugant per donor, respectively. Transfer of pPOB from strain B13-ST1 to strain B13 was observed in autoclaved soil but not in nonautoclaved soil; formation of transconjugant bacteria was more rapid in soil containing clay and organic matter than in sandy soil. Transfer of pPOB from strain POB310 to strain B13 in soil was never observed.

Abstract
Removal of dibenzofuran, dibenzo-p-dioxin, and 2-chlorodibenzo-p-dioxin (2-CDD) (10 ppm each) from soil microcosms to final concentrations in the parts-per-billion range was affected by the addition of Sphingomonas sp. strain RW1. Rates and extents of removal were influenced by the density of RW1 organisms. For 2-CDD, the rate of removal was dependent on the content of soil organic matter (SOM), with half-life values ranging from 5.8 h (0% SOM) to 26.3 h (5.5% SOM).

Abstract
A genetically engineered microorganism (GEM), Pseudomonas sp. B13 FRI (pFRC20P) (abbreviated FR120), has previously been engineered to simultaneously mineralize mixtures of methylated and chlorinated benzoic acids and phenols through a modified ortho cleavage pathway. In this study, its performance was investigated both in different types of aquatic microcosms and in pure culture to determine (1) if under simulated in situ conditions the genetically engineered pathway effectively removes mixtures of model pollutants simultaneously, quickly, and completely; (2) where the optimum pollutant concentration range for this activity lies; and (3) how physical, chemical, and biological factors in the microcosms influence degradation rates. Growth and degradation parameters of FR 120 in pure culture were determined with 3-chlorobenzoate (3CB), 4-methylbenzoate (4MB), and equimolar mixtures of both as carbon sources. These substrates were degraded simultaneously, albeit with different degradation velocities, by FR120. The optimum growth concentrations for 3CB and 4MB were 3.0 mm and 2.1 mM, respectively, and the inhibition constants (Ki) were 11 mm (3CB) and 6 mm (4MB). The pathway was induced at low concentrations of substrate (> 1 [μM). The first order degradation constants (kl) were determined with respect to substrate concentration, cell density, and temperature. In aquatic microcosms inoculated with FR120, first order degradation constants and half lives of target chemicals were calculated based on the total amount of aromatics recovered. Half lives ranged from 1.3 days to 3.0 days, depending on the target chemical and the type of microcosm. Degradation constants determined in pure culture were extrapolated to the densities of FR120, substrate concentrations, and temperature occurring in the microcosm experiments, and used to calculate theoretical half lives. In water microcosms, theoretical and observed half lives corresponded well, indicating that FR120 functioned optimally in this environment. In whole core sediment microcosms, and especially at low cell densities, the observed degradation activity was in some cases considerably higher than expected from pure culture degradation rates. This suggests that environmental conditions in the sediment were more favorable to the degradation of substituted aromatics than those in pure culture. The physiological characteristics of FR120 and its performance in aquatic microcosms make it a good candidate for bioremediation at sites contamninated with mixtures of chlorinated and methylated aromatics.

Abstract
Pseudomonas pseudoalcaligenes strain POB310 degrades 3- and 4-carboxydiphenyl ether. The initial reaction involves an angular dioxygenation yielding an unstable hemiacetal that spontaneously decays to phenol and protocatechuate. We cloned a DNA fragment containing the gene encoding the initial dioxygenase from an unstable, self-transmissible plasmid. Sequence analysis revealed two open reading frames encoding proteins with putative molecular masses of 46.3 and 33.6 kDa. The deduced amino acid sequences showed homologies to oxygenase and reductase subunits of aromatic ring-activating dioxygenases, and contained regions identical to consensus sequences that bind chloroplast-like and Rieske-type [2Fe2S] clusters, suggesting that the initial dioxygenase is a class IA aromatic ring-activating dioxygenase system. Initial dioxygenase activity was induced in bacteria grown in M9 minimal medium containing 3- or 4-carboxydiphenyl ether or phenol as carbon source, indicating that the regulation is dependent on the phenol pathway. The maximal specific activity was measured at the beginning of the exponential growth phase.

Abstract
Catechol 2,3-dioxygenase from the meta-cleavage pathway encoded on the TOL plasmid of Pseudomonas putida (pWWO) was investigated by electron microscopy. Negatively stained samples of the purified catechol 2,3-dioxygenase revealed that the enzyme consists of four subunits arranged in a tetrahedral conformation. Monoclonal antibodies raised against catechol 2,3-dioxygenase showed highly specific reactions and were used to localize the enzyme in Escherichia coli (pAW31) and P. putida (pWWO), using the protein A-gold technique carried out as a post-embedding immunoelectron microscopy procedure. Our in situ labeling studies revealed a cytoplasmic location of the catechol 2,3-dioxygenase in both cell types.

Abstract
In this report we describe the development and construction of a DNA module which encodes bph genes for the metabolism of PCBs and which is capable of stable integration into the chromosome of Gram negative bacteria. Introduction of the bph-module into Pseudomonas putida KT2442, Pseudomonas sp. strain B13 and its genetically engineered derivative B13FR1 expanded the biodegradative ability of these strains to include biphenyl and 4-chlorobiphenyl. The bph operon was stably inherited under laboratory conditions. Behavior of the genetically engineered strains was evaluated under simulated natural habitat conditions in lake sediment microcosms with respect to survival and removal of 4-chlorobiphenyl. The genetically engineered strains persisted under these conditions and were effective in degrading 4-chlorobiphenyl over a five day incubation period.

Abstract
Pseudomonas cepacia G4 degrades trichloroethylene (TCE) via a degradation pathway for aromatic compounds which is induced by substrates such as phenol and tryptophan. P. cepacia G4 5223 PR1 (PR1) is a Tn5 insertion mutant which constitutively expresses the toluene ortho-monooxygenase responsible for TCE degradation. In groundwater microcosms, phenol-induced strain G4 and noninduced strain PR1 degraded TCE (20 and 50 microM) to nondetectable levels (< 0.1 microM) within 24 h at densities of 10(8) cells per ml; at lower densities, degradation of TCE was not observed after 48 h. In aquifer sediment microcosms, TCE was reduced from 60 to < 0.1 microM within 24 h at 5 x 10(8) PR1 organisms per g (wet weight) of sediment and from 60 to 26 microM over a period of 10 weeks at 5 x 10(7) PR1 organisms per g. Viable G4 and PR1 cells decreased from approximately 10(7) to 10(4) per g over the 10-week period.

Abstract
A red-pigmented coryneform bacterium, identified as Rhodococcus rhodochrous strain 116, that grew on 2-ethoxyphenol and 4-methoxybenzoate as sole carbon and energy sources was isolated. Phylogenetic analysis based on the 16S rDNA sequences indicates that the strain clusters more closely to other rhodococci than to other gram-positive organisms with a high G + C content. Each of the abovementioned growth substrates was shown to induce a distinct cytochrome P-450: cytochrome P-450RR1 was induced by 2-ethoxyphenol, and cytochrome P-450RR2 was induced by 4-methoxybenzoate. A type I difference spectrum typical of substrate binding was induced in cytochrome P-450RR1 by both 2-ethoxyphenol (KS = 4.2 +/- 0.3 microM) and 2-methoxyphenol (KS = 2.0 +/- 0.1 microM), but not 4-methoxybenzoate or 4-ethoxybenzoate. Similarly, a type I difference spectrum was induced in cytochrome P-450RR2 by both 4-methoxybenzoate (KS = 2.1 +/- 0.1 microM) and 4-ethoxybenzoate (KS = 1.6 +/- 0.1 microM), but not 2-methoxyphenol or 2-ethoxyphenol. A purified polyclonal antiserum prepared against cytochrome P-450RR1 did not cross-react with cytochrome P-450RR2, indicating that the proteins are immunologically distinct. The cytochromes appear to catalyze the O-dealkylation of their respective substrates. The respective products of the O-dealkylation are further metabolized via ortho cleavage enzymes, whose expression is also regulated by the respective aromatic ethers.

Abstract
In this paper we describe a sediment microcosm system consisting of 20 undisturbed, layered sediment cores with overlying site water which are incubated under identical conditions of temperature, light, stirring rate of overlying water, and water exchange rate. Ecosystem parameters (nutrient level, photosynthetic potential, community structure of heterotrophic bacteria, thymidine incorporation rate, and oxygen microgradients) of the laboratory microcosms and the source ecosystem were compared and shown to be indistinguishable for the first 2 weeks. In weeks 3 and 4, small differences were detectable in the nutrient level, community structure of heterotrophic bacteria, and thymidine incorporation rate. However, the photosynthetic potential, depth profiles of heterotrophic bacterial community structure, and oxygen microgradients were maintained throughout the incubation period and did not differ between laboratory microcosms and the source ecosystem. The microcosm system described here would thus appear to be a valid model of aquatic sediments for up to 4 weeks; the actual period would depend on the sediment source and incubation temperature. The validated systems were used with Rhine river sediment to assess possible effects on ecosystem parameters of Pseudomonas sp. strain B13 FR1(pFRC20P), a genetically engineered microorganism (GEM) that had been constructed to degrade mixtures of halo- and alkylbenzoates and -phenols. The GEM survived in the surface sediment at densities of 5 x 10(4) to 5 x 10(5)/g (dry weight) for 4 weeks and degraded added chloro- and methylaromatics. The GEM did not measurably influence ecosystem parameters such as photosynthesis, densities of selected heterotrophic bacteria, thymidine incorporation rate, and oxygen microgradients. Thus, the microcosm system described here would seem to be useful for the study of the ecology of biodegradation and the fate and effect of microorganisms introduced into the environment.

Abstract
Pseudomonas sp. strain B13 FR1(pFRC20P) is a genetically engineered microorganism (GEM) which is able to degrade chloro- and methylaromatics through a constructed ortho cleavage pathway. The fate of the GEM and its ability to degrade substituted aromatic compounds in two different aquatic sediments was investigated by using a microcosm system which consisted of intact layered sediment cores with an overlying water column. The GEM survived in Lake Plussee and in Rhine river sediments at densities of approximately 10(5) bacteria per g (dry weight) (1 to 5% of the total CFU) throughout a 4-week period of investigation. According to several criteria, the microcosm system was stable and healthy throughout the experiment and the addition of the GEM did not affect the total number of extractable CFU (I. Wagner-Döbler, R. Pipke, K. N. Timmis, and D. F. Dwyer, Appl. Environ. Microbiol. 58:1249-1258, 1992). When compared with uninoculated controls, the presence of the GEM enhanced the rate of degradation of a mixture of 3-chlorobenzoate and 4-methylbenzoate (25 microns each) which had been added to the water column of the sediment cores.

Abstract
Two anaerobic bacteria were isolated from polyethylene glycol (PEG)-degrading, methanogenic, enrichment cultures obtained from a municipal sludge digester. One isolate, identified as Desulfovibrio desulfuricans (strain DG2), metabolized oligomers ranging from ethylene glycol (EG) to tetraethylene glycol. The other isolate, identified as a Bacteroides sp. (strain PG1), metabolized diethylene glycol and polymers of PEG up to an average molecular mass of 20,000 g/mol [PEG 20000; HO-(CH2-CH2-O-)nH]. Both strains produced acetaldehyde as an intermediate, with acetate, ethanol, and hydrogen as end products. In coculture with a Methanobacterium sp., the end products were acetate and methane. Polypropylene glycol [HO-(CH2-CH2-CH2-O-)nH] was not metabolized by either bacterium, and methanogenic enrichments could not be obtained on this substrate. Cell extracts of both bacteria dehydrogenated EG, PEGs up to PEG 400 in size, acetaldehyde, and other mono- and dihydroxylated compounds. Extracts of Bacteroides strain PG1 could not dehydrogenate long polymers of PEG (greater than or equal to 1,000 g/mol), but the bacterium grew with PEG 1000 or PEG 20000 as a substrate and therefore possesses a mechanism for PEG depolymerization not present in cell extracts. In contrast, extracts of D. desulfuricans DG2 dehydrogenated long polymers of PEG, but whole cells did not grow with these polymers as substrates. This indicated that the bacterium could not convert PEG to a product suitable for uptake.

Abstract

. The enrichment contained members of three physiological groups necessary for the syntrophic mineralization of phenol: a phenol-oxidizing bacterium, a
Methanothrix
-like bacterium, and an H

-utilizing methanogen. The immobilization technique resulted in the cells being embedded in a long, thin agar strand (1 mm in diameter by 2 to 50 cm in length) that resembled spaghetti. Immobilization had three effects as shown by a comparative kinetic analysis of phenol degradation by free versus immobilized cells. (i) The maximum rate of degradation was reduced from 14.8 to 10.0 μg of phenol per h; (ii) the apparent
K
m
for the overall reaction was reduced from 90 to 46 μg of phenol per ml, probably because of the retention of acetate, H
2
and CO

in the proximity of immobilized methanogens; and (iii) the cells were protected from substrate inhibition caused by high concentrations of phenol, which increased the apparent
K

value from 900 to 1,725 μg of phenol per ml. Estimates for the kinetic parameters

Abstract
Methanogenic enrichments capable of degrading polyethylene glycol and ethylene glycol were obtained from sewage sludge. Ethanol, acetate, methane, and (in the case of polyethylene glycols) ethylene glycol were detected as products. The sequence of product formation suggested that the ethylene oxide unit [HO-(CH2-CH2-O-)xH] was dismutated to acetate and ethanol; ethanol was subsequently oxidized to acetate by a syntrophic association that produced methane. The rates of degradation for ethylene, diethylene, and polyethylene glycol with molecular weights of 400, 1,000, and 20,000, respectively, were inversely related to the number of ethylene oxide monomers per molecule and ranged from 0.84 to 0.13 mM ethylene oxide units degraded per h. The enrichments were shown to best metabolize glycols close to the molecular weight of the substrate on which they were enriched. The anaerobic degradation of polyethylene glycol (molecular weight, 20,000) may be important in the light of the general resistance of polyethylene glycols to aerobic degradation.
