Zhang Q, Cheng YF, Huang BC, Jin RC. A review of heavy metals inhibitory effects in the process of anaerobic ammonium oxidation. JOURNAL OF HAZARDOUS MATERIALS 2022; 429:128362.

Abstract
Anaerobic ammonium oxidation (anammox) is a promising biological technology for treating ammonium-rich wastewaters. However, due to the high sensitivity of anammox bacteria, many external factors have inhibitory effects on this process. As one of the commonly found toxic substances in wastewater, heavy metals (HMs) are possible to cause inhibition on anammox sludge, which then results in a declined treatment performance. Getting insights into the response mechanism of anammox sludge to HMs is meaningful for its application in treating this kind of wastewater. This review summarized the effect of different HMs on treatment performance of anammox bioreactor. In addition, the mechanism of toxication raised by HMs was discussed. Also, the potential mitigation strategies were summarized and the future prospects were outlooked. This review might provide useful information for both scientific research on and engineering application of anammox process for treating HMs containing wastewater.

Abstract
Identification and detection of harmful contaminants such as nickel and other materials from soil and water is critical necessity at the present moment. So with this motive to detect and identify harmful pollutants, a novel cyclotriveratrylene based derivative was prepared for the detection and binding of harmful pollutants which had the properties of fluorescence. The newly derivative of Cyclotriveratrylene was found to be highly sensitive and selective towards Ni2+ ions. The complexation behaviour of this newly synthesised molecule was studied in presence of transition elements. Also computational methods such as docking, molecular modelling and DFT were used to study the molecular orbitals and energies of CTG-NBEP. The detection of Ni2+ from water samples were also carried out successfully.

The inhibitory impact of ammonia on thermally hydrolyzed sludge fed anaerobic digestion. WATER ENVIRONMENT RESEARCH : A RESEARCH PUBLICATION OF THE WATER ENVIRONMENT FEDERATION 2021; 93:1263-1275. [PMID: 33423314 DOI: 10.1002/wer.1509] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [MESH Headings] [Track Full Text] [Subscribe] [Scholar Register] [Received: 03/20/2020] [Revised: 09/08/2020] [Accepted: 09/14/2020] [Indexed: 06/12/2023]
Abstract
This study evaluated the impact of ammonia on mesophilic anaerobic digestion (AD) with thermal hydrolysis pretreatment (THP) treating a mixture of primary sludge and waste activated sludge and operated under constant organic loading rate of 9 kg COD/m3 /d. Free ammonia concentrations in the digesters were varied between 37 and 966 mg NH3 -N/L, while maintaining all other operational conditions constant. A decrease in volatile solids reduction from 54 ± 5% (at <554 mg NH3 -N/L) to 35 ± 6% at the maximum free ammonia concentration of 966 mg NH3 -N/L was observed at steady-state conditions. No impact of free ammonia on final dewaterability was detected. Free ammonia thus mostly limited methanogenesis. A free ammonia Monod inhibition constant of 847 ± 222 mg NH3 -N/L for methanogens was estimated based on the digester steady-state methane rates dynamics. This study showed that current THP AD digesters (typically 110-260 mg NH3 -N/L) operate under 12%-18% ammonia inhibition for methanogenesis. Operation under SRT of 15 days, about 2 times more than needed to retain methanogens, can compensate for lower methanogens rates and avoid performance impacts. The later shows a good potential to operate under higher free and total ammonia concentration without jeopardizing performance. PRACTITIONER POINTS: Only from a free ammonia concentration above 554 mg NH3 -N/L, decreased volatile solids reduction and biogas yield were observed. A volatile solids reduction of 35 ± 6% at maximum free ammonia concentration of 966 mg NH3 -N/L was still achieved. A Monod inhibition constant for methanogens of 847 ± 222 mg NH3 -N/L was estimated. It was estimated that current THP AD systems (110-260 mg NH3 -N/L) operate under 12%-18% NH3 inhibition for methanogenesis.

Abstract
Large amounts of industrial metal containing process and waste solutions are a growing issue. In this work, we demonstrated that they could be transformed into materials of high added values such as copper-nickel nanowires (CuNi NWs) by simple chemical reduction. A thorough investigation of the parameter space was conducted. The microstructure of the obtained material was found tunable depending on the employed concentration of precursor, reducing agent, capping agent, pH, temperature, and reaction time. Moreover, the obtained product had a strong magnetic character, which enabled us to separate it from the reaction medium with ease. The results open new perspectives for materials science by proposing a new type of nanostructure: composite NWs of very promising properties, with metallic elements originating directly from industrial process solution.

Azolla filiculoides L. as a source of metal-tolerant microorganisms. PLoS One 2020; 15:e0232699.

Abstract
The metal hyperaccumulator Azolla filiculoides is accompanied by a microbiome potentially supporting plant during exposition to heavy metals. We hypothesized that the microbiome exposition to selected heavy metals will reveal metal tolerant strains. We used Next Generation Sequencing technique to identify possible metal tolerant strains isolated from the metal-treated plant (Pb, Cd, Cr(VI), Ni, Au, Ag). The main dominants were Cyanobacteria and Proteobacteria constituting together more than 97% of all reads. Metal treatment led to changes in the composition of the microbiome and showed significantly higher richness in the Pb-, Cd- and Cr-treated plant in comparison with other (95–105 versus 36–44). In these treatments the share of subdominant Actinobacteria (0.4–0.8%), Firmicutes (0.5–0.9%) and Bacteroidetes (0.2–0.9%) were higher than in non-treated plant (respectively: 0.02, 0.2 and 0.001%) and Ni-, Au- and Ag-treatments (respectively: <0.4%, <0.2% and up to 0.2%). The exception was Au-treatment displaying the abundance 1.86% of Bacteroidetes. In addition, possible metal tolerant genera, namely: Acinetobacter, Asticcacaulis, Anabaena, Bacillus, Brevundimonas, Burkholderia, Dyella, Methyloversatilis, Rhizobium and Staphylococcus, which form the core microbiome, were recognized by combining their abundance in all samples with literature data. Additionally, the presence of known metal tolerant genera was confirmed: Mucilaginibacter, Pseudomonas, Mycobacterium, Corynebacterium, Stenotrophomonas, Clostridium, Micrococcus, Achromobacter, Geobacter, Flavobacterium, Arthrobacter and Delftia. We have evidenced that A. filiculoides possess a microbiome whose representatives belong to metal-resistant species which makes the fern the source of biotechnologically useful microorganisms for remediation processes.

Abstract
Nickel has long been known to be an important human toxicant, including having the ability to form carcinomas, but until recently nickel was believed to be an issue only to microorganisms living in nickel-rich serpentine soils or areas contaminated by industrial pollution. This assumption was overturned by the discovery of a nickel defense system (RcnR/RcnA) found in microorganisms that live in a wide range of environmental niches, suggesting that nickel homeostasis is a general biological concern. To date, the mechanisms of nickel toxicity in microorganisms and higher eukaryotes are poorly understood. In this review, we summarize nickel homeostasis processes used by microorganisms and highlight in vivo and in vitro effects of exposure to elevated concentrations of nickel. On the basis of this evidence we propose four mechanisms of nickel toxicity: (1) nickel replaces the essential metal of metalloproteins, (2) nickel binds to catalytic residues of non-metalloenzymes; (3) nickel binds outside the catalytic site of an enzyme to inhibit allosterically and (4) nickel indirectly causes oxidative stress.

Abstract
A common microbial strategy for detoxifying metals involves redox transformation which often results in metal precipitation and/or immobilization. In the present study, the influence of ionic nickel [Ni(II)] on growth of the purple sulfur bacterium Thiocapsa roseopersicina was investigated. The results suggest that Ni(II) in the bulk medium at micromolar concentrations results in growth inhibition, specifically an increase in the lag phase of growth, a decrease in the specific growth rate, and a decrease in total protein concentration when compared to growth controls containing no added Ni(II). The inhibitory effects of Ni(II) on the growth of T. roseopersicina could be partially overcome by the addition of hydrogen (H(2)) gas. However, the inhibitory effects of Ni(II) on the growth of T. roseopersicina were not alleviated by H(2) in a strain containing deletions in all hydrogenase-encoding genes. Transmission electron micrographs of wild-type T. roseopersicina grown in the presence of Ni(II) and H(2) revealed a significantly greater number of dense nanoparticulates associated with the cells when compared to wild-type cells grown in the absence of H(2) and hydrogenase mutant strains grown in the presence of H(2). X-ray diffraction and vibrating sample magnetometry of the dense nanoparticles indicated the presence of zerovalent Ni, suggesting Ni(II) reduction. Purified T. roseopersicina hyn-encoded hydrogenase catalyzed the formation of zerovalent Ni particles in vitro, suggesting a role for this hydrogenase in Ni(II) reduction in vivo. Collectively, these results suggest a link among H(2) metabolism, Ni(II) tolerance, and Ni(II) reduction in T. roseopersicina .

Abstract
Sixty six isolates of Pseudomonas spp. were isolated from wastewater of El-Malah canal located in Assiut, Egypt and were checked for their heavy metal tolerance. One isolate has tested for its multiple metal resistances and found to be plasmid mediated with molecular weight 27 Kb for nickel and lead. It was identified as Pseudomonas aeruginosa ASU 6a. Its minimal inhibitory concentration (MIC) for Cu(2+), Co(2+), Ni(2+), Zn(2+), Cr(3+), Cd(2+)and Pb(2+) were 6.3, 5.9, 6.8, 9.2, 5.8, 4.4, and 3.1 mM, respectively. Growth kinetics and the maximum adsorption capacities were determined under Ni(2+) and Pb(2+) stress. The latter heavy metals induced potassium efflux and were used as indicator for plasma membrane permeabilization.

Abstract
NikR proteins are bacterial metallo-regulatory transcription factors that control the expression of the nickel uptake system and/or nickel containing enzymes such as urease, and are involved in the acid stress response. Here, a comparative study is reported on NikR from Helicobacter pylori (HpNikR) and Escherichia coli (EcNikR), as well as the Q2E mutant of EcNikR. Most attention was focused on the Ni(II) binding properties of these proteins, as a function of pH. The influence of the pH on the Ni(II) binding and aggregation properties was studied using gel filtration analysis and UV-visible absorption spectroscopy in the presence of an increasing concentration of nickel. Q2E and wt EcNikR are identical in Ni(II) binding but the Q2E mutant is impaired to some extent in DNA-binding. For EcNikR it is shown that between pH 6 and 8, addition of Ni(II) above 1 equiv. induces mass aggregation and precipitation, concomitant with binding of Ni(II) up to a maximum of 5-8 Ni(II) ions per monomer. The Ni(II) site with highest affinity is the well-described square planar site with three histidines and one cysteine ligands. Aggregation is complete in the presence of less than 1 extra equiv. of Ni(II) and aggregation is fully reversible and precipitates are rapidly solubilized by addition of EDTA. The sensitivity of EcNikR to aggregation decreases with decreasing pH, concurrent with histidines being the main ligands of the site responsible for aggregation. HpNikR does not display aggregation except at alkaline pH, where 3 Ni(II) equiv. are needed. The participation of a cluster consisting of surface-exposed histidines present in EcNikR but not in HpNikR, is proposed to be involved in aggregation. Our results on HpNikR are compatible with the crystallographic data and with the ability of this protein to bind more than one nickel.

Abstract
Eighteen Frankia strains originally isolated from nine different host plants were used to study the biodiversity of hydrogenase in Frankia. In the physiological analysis, the activities of uptake hydrogenase and bidirectional hydrogenase were performed by monitoring the oxidation of hydrogen after supplying the cells with 1% hydrogen and the evolution of hydrogen using methyl viologen as an electron donor, respectively. These analyses were supported with a study of the immunological relationship between Frankia hydrogenase and other different known hydrogenases from other microorganisms. Uptake hydrogenase activity was recorded from all the Frankia strains investigated. A methyl-viologen-mediated hydrogen evolution was recorded from only four Frankia strains irrespective of the source of Frankia. From the immunological and physiological studies, we here report that there are at least three types of hydrogenases in Frankia: Ni-Fe uptake hydrogenase, hydrogen-evolving hydrogenase, and [Fe]-hydrogenase. An immunogold localization study, by cryosection technique, of the effect of nickel on the intercellular distribution of hydrogenase proteins in Frankia indicated that nickel affects the transfer of hydrogenase proteins into the membrane.

Abstract
The heavy metal-resistant bacterial strain SJ-101 has been isolated from fly ash contaminated soil. Based on the morphological and biochemical characteristics, the isolate SJ-101 was presumptively identified as Bacillus sp. The adsorption isotherms revealed the absolute adsorption capacity (Q degrees) of 244 mg Ni g(-1) dry cell mass vis-à-vis 161 mg Ni g(-1) synthetic resin (Amberlite IR-120). The higher relative adsorption capacity (K(F)) of 7.37, and the intensity of adsorption (1/n) of 0.58 with dry cell biomass suggested higher affinity of Bacillus cells towards nickel ions. The data conform to the Langmuir adsorption model relatively better than the Freundlich model. The thermodynamic parameters indicated the feasibility, endothermic, and interactive nature of nickel adsorption process on the cell surface. Higher Ni tolerance and sorption capacity of Bacillus sp. SJ-101, explicitly signifies its implications in Ni bioremediation process.

Abstract
Bacteria have evolved a number of tightly controlled import and export systems to maintain intracellular levels of the essential but potentially toxic metal nickel. Nickel homeostasis systems include the dedicated nickel uptake system nik found in Escherichia coli, a member of the ABC family of transporters, that involves a periplasmic nickel-binding protein, NikA. This is the initial nickel receptor and mediator of the chemotactic response away from nickel. We have solved the crystal structure of NikA protein in the presence and absence of nickel, showing that it behaves as a "classical" periplasmic binding protein. In contrast to other binding proteins, however, the ligand remains accessible to the solvent and is not completely enclosed. No direct bonds are formed between the metal cation and the protein. The nickel binding site is apolar, quite unlike any previously characterized protein nickel binding site. Despite relatively weak binding, NikA is specific for nickel. Using isothermal titration calorimetry, the dissociation constant for nickel was found to be approximately 10 microm and that for cobalt was approximately 20 times higher.

Abstract
There are two distinct nickel resistance loci on plasmid pTOM9 from Achromobacter xylosoxidans 31A, ncc and nre. Expression of the nreB gene was specifically induced by nickel and conferred nickel resistance on both A. xylosoxidans 31A and Escherichia coli. E. coli cells expressing nreB showed reduced accumulation of Ni(2+), suggesting that NreB mediated nickel efflux. The histidine-rich C-terminal region of NreB was not essential but contributed to maximal Ni(2+) resistance.

Abstract
Expression of the nickel-specific transport system encoded by the Escherichia coli nikABCDE operon is repressed by a high concentration of nickel. By using random transposon Tn10 insertion, we isolated mutants in which expression of the nik operon became constitutive with respect to nickel. We have identified the corresponding nikR gene which encodes a nickel-responsive regulator. Expression of nikR was partially controlled by Fnr through transcription from the nikA promoter region. In addition, a specific transcription start site for the constitutive expression of nikR was found 51 bp upstream of the nikR gene.

Abstract
Bacillus subtilis and Agrobacterium radiobacter remained viable when exposed to Ni (1 x 10(-4)M; ionic strength (mu) = 3 x 10(-4)) at pH values known to cause a change of the net negative charge of the cells to a net positive charge (charge reversal). The gross morphology, as determined by scanning electron microscopy, of these and other bacteria and of Saccharomyces cerevisiae was not altered in the presence of Ni, Cu, and Zn (1 x 10(-4) M; mu = 3 x 10(-4)), which caused a charge reversal at pH values between 6.0 and 9.0. Similar results were obtained in the presence of Na and Mg, which did not cause charge reversal at the same mu and pH values. These results confirmed that cells remain viable when their surface charge is changed in the presence of some heavy metals at high pH values.

Abstract
The nik operon of Escherichia coli encodes a periplasmic binding-protein-dependent transport system specific for nickel. In this report, we describe the overproduction of the periplasmic nickel-binding protein NikA by cloning the nikA gene into an overexpression vector, pRE1. NikA was purified free of nickel to near homogeneity from the periplasm by hydrophobic and ion-exchange chromatography. N-terminal amino acid sequencing confirmed that the leader peptide of NikA had been removed. The nickel-binding properties of the protein has been studied by monitoring the quenching of intrinsic protein fluorescence. NikA binds one atom of nickel/molecule of protein with a dissociation constant (Kd) of less than 0.1 microM. Other metals (cobalt, copper, iron) are bound at least 10-fold less tightly. The high specificity for Ni2+ is also demonstrated by high-performance immobilized-metal-ion affinity chromatography. Biosynthesis of NikA occurred only under anaerobic conditions and was dependent on the general anaerobic regulator FNR. It was repressed by the presence of 250 microM Ni2+ in the growth medium and was not affected by either 30 mM formate or 100 mM nitrate. Anaerobically grown wild-type strain MC4100 contains about 23,000 molecules of NikA/cell. In addition to the effect on nickel transport, nikA mutation affects also the nickel sensing in Tar-dependent repellent chemotaxis.

Abstract
Two zinc (Zn)-resistant strains, AnZn-1 and AnZn-2, which were resistant to ZnSO4 up to 12.5 mg ml(-1) were isolated from industrial effluents. Both were Gram-negative with motile cells. They exhibited tolerance to Ba2+, Ni+, Co2+, Mn2+, Cu2+, Fe2+, Ni2+, Cd2+, kanamycin, chloramphenicol, ampillicin and tetracycline, but were sensitive to Hg2+ and streptomycin. For AnZn-1 and AnZn-2, the optimum pH for growth was 7. Both were facultative anaerobes and had cytochrome oxidase and urease enzymes, while catalase was present only in AnZn-2. Both strains had the ability to hydrolyse gelatin, reduce nitrate, and yield acid from arabinose and rhamnose. The two strains shared maximum characters with Vibrionaceae. Each strain carries a single Zn-resistant conjugative plasmid. The plasmid residing in AnZn-1 (pSH1211) displayed a lower level of resistance than the plasmid of AnZn-2 (pSH1212). Both required a minimum of 24 h for mating and showed highest transfer frequency at 25 degrees C. pSH1211 preferred pH 7 and pSH1212 pH 8.5 for their transfer. Both plasmids, when allowed to mate with Escherichia coli at 25 degrees C, alkaline pH values of 8-8.5 (pSH1211) of pH 7.5 (pSH1212), showed increased transfer frequency.

Abstract
Systematic screening of 6.10(4) independent Tn5 insertion mutants of Escherichia coli yielded one new hydrogenase locus, hydF, mapping near 64.8 min, i.e., close to the hydL locus (K. Stoker, L.F. Oltmann, and A.H. Stouthamer, J. Bacteriol. 170:1220-1226, 1988). It regulated specifically the activity of the hydrogenase isoenzymes, formate dehydrogenase and lyase activities being unaffected. In hydF mutants, hydrogenase 1 and 2 activities were reduced to 1% of the parental level, whereas the electrophoretically labile part was present at about 20% of the parental level. H2 uptake was also reduced to about 20%, which suggested a relationship between these two activities. Experiments with 63Ni indicated that hydrogenase isoenzymes 1 and 2 might be present in these strains but in an inactive form. The hydF product might therefore be a posttranslational activator. At least three other mutant classes were isolated. Additional data were obtained on coisolated, nickel-restorable hydC mutants (L.F. Wu and M.-A. Mandrand-Berthelot, Biochimie 68:167-179, 1986). These strains were found to suffer a general impairment of nickel uptake. Restoration of hydrogenase activities was specific for NiCl2 and inhibited by chloramphenicol, which indicated an effect either on the transcription of hydrogenase(-associated) genes or by cotranslational incorporation in nickel-containing enzymes (e.g., in hydrogenases). The hydC mutation could not be complemented in trans, evidence that the hydC product is not a nickel transport protein but rather a cis-acting regulatory gene. Parent HB101, hydF mutants, and the other mutants were further analyzed by monitoring the induction of hydrogenase and hydrogenase-associated activities upon transition of cells from aerobic to anaerobic growth. These experiments also revealed a correlation between the early-induced H2 uptake route and labile hydrogenase activity. The formate hydrogenlyase induction patterns followed quite well the slower induction patterns of hydrogenases 1 and 2.

Abstract
Sixty-two aerobic bacterial strains isolated from the unproductive dystrophic Lake Skärshultsjön (South Sweden) were screened for plasmids. The lake is considered to be an extreme environment because of its high concentration of persistent but nontoxic humic compounds. One-third of the isolates harbored multiple plasmids usually of similar high molecular weights (>25 Mdal). The plasmid-bearing strains were members of the common aquatic taxaPseudomonas spp.,Acinetobacter sp.,Alcaligenes sp.,Aeromonas/Vibrio group, andEnterobacteriaceae (taxonomy is tentative). The majority of isolates displayed multiple resistance to antibiotics and heavy metals. Some of them were capable of degrading aromatic compounds. Three isolates were chosen for curing experiments. Only strain S-68, anAlcaligenes sp., could be cured of one of its two plasmids. It harbored the two cryptic plasmids pQQ32 and pQQ70 of 32 and ca. 70 Mdal, and the latter was segregated during ethidium bromide treatment. Parental strain S-68 was capable of degrading some of nonchlorinated phenolic compounds and displayed resistance to a broad spectrum of antibiotics and the heavy metals Co(2+), Ni(2+), Zn(2+), Cd(2+), and Hg(2+). Derivative strain S-68-41 lost its resistance to nickel, suggesting segregated plasmid PQQ70 coded for nickel resistance. Transformation experiments to restore nickel resistance in the cured derivative strain were not successful.

Abstract
The uptake of nickel ions by the cyanobacterium Anabaena cylindrica was studied. Nickel transport was dependent on the membrane potential of the cells and the rate of uptake was decreased in the dark or by the addition of inhibitors, including uncouplers and electron transport inhibitors, which decreased or abolished the membrane potential of cells. The transport process obeyed hyperbolic kinetics, with a high affinity (apparent Km = 17 +/- 11 (SEM) nM) and low turnover number (maximum velocity = 22.3 +/- 5.4 (SEM) pmol h-1 mg dry wt-1 of cells or flux rate of 3.1 nmol h-1 m-2 of plasma membrane surface area). The process was also apparently specific for Ni2+, the rate being unaffected by the presence of a range of other metal ions in large excess. Equilibrium experiments showed that, over a range of nickel ion concentrations, the cells concentrated Ni2+ by a factor of 2700 +/- 240 (SEM)-fold, corresponding to a chemical diffusion potential for Ni2+ of 101 mV. It was concluded that the cells transport nickel ions by a carrier-facilitated transport process with the concentration factor for the ions being determined by the cell membrane potential according to the Nernst equation.

Abstract
The hydrogenase activities of the heterocystous cyanobacteria Anabaena cylindrica and Mastigocladus laminosus are nickel dependent, based on their inability to consume hydrogen with various electron acceptors or produce hydrogen with dithionite-reduced methyl viologen, after growth in nickel-depleted medium. Upon addition of nickel ions to nickel-deficient cultures of A. cylindrica, the hydrogenase activity recovered in a manner which was protein synthesis-dependent, the recovery being inhibited by chloramphenicol. We have used the nickel dependence of the hydrogenase as a probe of the possible roles of H2 consumption in enhancing nitrogen fixation, and particularly for protecting nitrogenase against oxygen inhibition. Although at the usual growth temperatures (25 degrees for A. cylindrica and 40 degrees for M. laminosus), the cells consume H2 vigorously in an oxyhydrogen reaction after growth in the presence of nickel ions, we have not found that the reaction confers any significant additional protection of nitrogenase, either at aerobic pO2 (for both organisms) or at elevated pO2 (for A. cylindrica). However, at elevated temperatures (e.g., 40 degrees for A. cylindrica and 48 degrees for M. laminosus) a definite protective effect was observed. At these temperatures both organisms rapidly lost acetylene reduction activity under aerobic conditions. When hydrogen gas (10%) was present, the cells retained approximately 50% of the nitrogenase activity observed under anaerobic conditions (argon gas phase). No such protection by hydrogen gas was observed with nickel-deficient cells. Studies with cell-free extracts of A. cylindrica showed that the predominant effect of temperature was not due to thermal inactivation of nitrogenase.

Abstract
Alcaligenes eutrophus strain CH34, which was isolated as a bacterium resistant to cobalt, zinc, and cadmium ions, shares with A. eutrophus strain H16 the ability to grow lithoautotrophically on molecular hydrogen, to form a cytoplasmic NAD-reducing and a membrane-bound hydrogenase, and most metabolic attributes; however, it does not grow on fructose. Strain CH34 contains two plasmids, pMOL28 (163 kilobases) specifying nickel, mercury, and cobalt resistance and pMOL30 (238 kilobases) specifying zinc, cadmium, mercury, and cobalt resistance. The plasmids are self-transmissible in homologous matings, but at low frequencies. The transfer frequency was strongly increased with IncP1 plasmids RP4 and pUZ8 as helper plasmids. The phenotypes of the wild type, cured strains, and transconjugants are characterized by the following MICs (Micromolar) in strains with the indicated phenotypes: Nic+, 2.5; Nic-, 0.6; Cob+A, 5.0; Cob+B, 20.0; Cob-, less than 0.07; Zin+, 12.0; Zin-, 0.6; Cad+, 2.5; and Cad-, 0.6. Plasmid-free cells of strain CH34 are still able to grow lithoautotrophically and to form both hydrogenases, indicating that the hydrogenase genes are located on the chromosome, in contrast to the Hox structural genes of strain H16, which are located on the megaplasmid pHG1 (450 kilobases).
