CHEMOSPHERE 2024; 350:141105. [PMID: 38171394 DOI: 10.1016/j.chemosphere.2023.141105] [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: 05/22/2023] [Revised: 12/11/2023] [Accepted: 12/31/2023] [Indexed: 01/05/2024]
Abstract
The efficient biodegradation of volatile chlorinated hydrocarbons using microbial fuel cells (MFCs) offers a feasible approach for purifying waste gas and alleviating energy crises. However, power generation is limited by poor pollutant biodegradation and slow electron transfer. The bifunctional bacterium Acinetobacter sp. HY-99C was screened and used to improve the performance of a conventional MFC. The inoculation of strain HY-99C into the conventional MFC promoted the formation of a compact biofilm with high metabolic activity and an enriched bifunctional genus (Acinetobacter), which resulted in the accelerated decomposition of chlorinated aromatic compounds into biodegradable organic acids. This led to efficient chlorobenzene removal and power generation from the MFC, with a chlorobenzene elimination capacity of 70.8 g m-3 h-1 and power density of 89.6 mW m-2, which are improved over those of previously reported MFCs. This study provides novel insights into enhancing pollutant removal and power generation in MFCs.

[PMID: 36529174 DOI: 10.1016/j.chemosphere.2022.137542] [Citation(s) in RCA: 1] [Impact Index Per Article: 1.0] [Reference Citation Analysis] [Abstract] [Key Words] [MESH Headings] [Track Full Text] [Subscribe] [Scholar Register] [Received: 09/25/2022] [Revised: 11/21/2022] [Accepted: 12/11/2022] [Indexed: 06/17/2023]
Abstract
The treatment of waste-gas containing chlorinated volatile organic compounds (CVOCs) has become a difficult issue in current air pollution control. Biotrickling filters (BTFs) have been recognized to be applicable for the treatment of CVOCs, but research on the biodegradation of binary gaseous CVOCs is rare. Herein, a BTF inoculated with Methylobacterium (M.) rhodesianum H13, Starkeya sp. T-2 and activated sludge was established to investigate the biodegradation of the gaseous dichloromethane (DCM) and 1,2-dichloroethane (1,2-DCE) and their interactions implicated. The bioaugmented BTF showed a faster startup (13 days), better removal efficiencies of DCM (80%) and 1,2-DCE (72%), and superior mineralization (65.9%) than that inoculated with activated sludge alone. The ECs of DCM and 1,2-DCE were positively related with the inlet load when the total inlet load was <50 g m-3 h-1. However, inlet loads higher than 50 g m-3 h-1 led to dramatic drop of the RE of DCM and 1,2-DCE due to the limitation of the degradation capacity of microorganisms and the toxic effect of high-concentration substrates. Besides, BTF could stand a lower shock load of 400 mg m-3, while higher shock loads would deteriorate the RE of DCM and 1,2-DCE. And BTF showed better impact resistance toward DCM than 1,2-DCE, probably because the 1,2-DCE biodegrading bacteria was more sensitive to the concentration change. For the same reason, the removal recovery of DCM after starvation was quicker than 1,2-DCE. Kinetic interactions were quantified by the EC-SKIP model, results of which revealed that DCM cast negative effect on 1,2-DCE biodegradation, while 1,2-DCE could promote DCM biodegradation. Moreover, both the results of real-time PCR and high-throughput sequencing showed M. rhodesianum H13 had stronger competitiveness and adaptability than Starkeya sp. T-2. The survived M. rhodesianum H13 and Starkeya sp. T-2 after starvation robustly demonstrated the success of bioaugmentation as well as its great potential of engineering application.

JOURNAL OF ENVIRONMENTAL MANAGEMENT 2022; 320:115951.

Abstract
In this study, the effect of rhamnolipids (RL) on m-dichlorobenzene (m-DCB) removal and biofilm was investigated in two biotrickling filters (BTF) (BTF1: blank control; BTF2: RL addition). The critical micelle concentration (CMC) value of RL was 75.6 mg L-1, and the RL could significantly improve the solubilization of m-DCB. The results showed that the optimal concentration of RL was 180 mg L-1. The removal efficiency (RE) of m-DCB dropped by 42.4% for BTF1 no fed with RL and only 28.2% for BTF2 fed with RL when the inlet concentration increased from 200 to 1400 mg m-3 at an empty bed time (EBRT) of 60 s. RL increased the secretion of extracellular polymers (EPS) and the ratio of Protein/Polysaccharide, which improved the mass transfer of m-DCB to the biofilm. RL also had a facilitating effect on catechol-1,2-dioxygenase (C12O) enzyme activity. Furthermore, RL increased Zeta potential and facilitated microorganisms to form biofilm. The dominant microorganisms of microbial community were increased and the application of RL promoted the enrichment of them.

Abstract
The prospection of new degrading enzymes of the plant cell wall has been the subject of many studies and is fundamental for industries, due to the great biotechnological importance of achieving a more efficient depolymerization conversion from plant polysaccharides to fermentable sugars, which are useful not only for biofuel production but also for various bioproducts. Thus, we explored the shotgun metagenome data of a bacterial community (CB10) isolated from sugarcane bagasse and recovered three metagenome-assembled genomes (MAGs). The genomic distance analyses, along with phylogenetic analysis, revealed the presence of a putative novel Chitinophaga species, a Pandoraea nosoerga, and Labrys sp. isolate. The isolation process for each one of these bacterial lineages from the community was carried out in order to relate them with the MAGs. The recovered draft genomes have reasonable completeness (72.67-100%) and contamination (0.26-2.66%) considering the respective marker lineage for Chitinophaga (Bacteroidetes), Pandoraea (Burkholderiales), and Labrys (Rhizobiales). The in-vitro assay detected cellulolytic activity (endoglucanases) only for the isolate Chitinophaga, and its genome analysis revealed 319 CAZymes, of which 115 are classified as plant cell wall degrading enzymes, which can act in fractions of hemicellulose and pectin. Our study highlights the potential of this Chitinophaga isolate provides several plant-polysaccharide-degrading enzymes.

Abstract
Understanding the degradation of pentachlorophenol (PCP) by indigenous microorganisms stimulated by an electron donor and shuttle in paddy soil, and the influences of PCP/electron donor/shuttle on the native microbial community are important for biodegradation and ecological and environmental safety. Previous studies focused on the kinetics and the microbial actions of PCP degradation, however, the effects of toxic and antimicrobial PCP and electron donor/shuttle on the microbial community diversity and composition in paddy soil are poorly understood. In this study, the effects of PCP, an electron donor (lactate), and the electron shuttle (anthraquinone-2, 6-disulfonate, AQDS) on the microbial community in paddy soil were investigated. The results showed that the presence of PCP reduced the microbial diversity compared to the control during PCP degradation, while increased the microbial diversity was observed in response to lactate and AQDS. The addition of PCP stimulated the microorganisms involved in PCP dechlorination, including Clostridium, Desulfitobacterium, Pandoraea, and unclassified Veillonellaceae, which were dormant in raw soil without PCP stress. In all of the treatments with PCP, the addition of lactate or AQDS enhanced PCP dechlorination by stimulating the growth of functional groups involved in PCP dechlorination and by changing the microbial community during dechlorination process. The microbial community tended to be uniform after complete PCP degradation (28 days). However, when lactate and AQDS were present simultaneously in PCP-contaminated soil, lactate acted as a carbon source or electron donor to promote the activities of microbial community, and AQDS changed the redox potential because of the production of reduced AQDS. These findings enhance our understanding of the effect of PCP and a biostimulation method for PCP biodegradation in soil ecosystems at the microbial community level, and suggest the appropriate selection of an electron donor/shuttle for accelerating the bioremediation of PCP-contaminated soils.

Abstract
The aim of this study was to evaluate the influence of rhamnolipid (RL) and ferric ions on the performance of a biotrickling filter (BTF) for the removal of gas-phase 1,2-dichlorobenzene (o-DCB). A comprehensive investigation of microbial growth, pollutant solubility, extracellular polymeric substances (EPS) and enzymatic activity in o-DCB degradation by an isolated strain Bacillus cereus DL-1 with/without RL and Fe3+ were carried out using batch microcosm experiments. In addition, o-DCB removal performance, biofilm morphology, and microbial community structures in two identical lab-scale biotrickling filters (named BTF1 and BTF2) inoculated with strain DL-1 were studied. The batch microcosm experiments demonstrated that 120 mg L-1 RL and 4 mg L-1 Fe3+ could enhance the biodegradation of o-DCB, which may be due to promotion on bacterial growth, o-DCB solubilization, C12O enzyme activity, and polysaccharide (PS) and protein (PN) in EPS. Fourier transform infrared (FTIR) spectra indicated that the addition of RL with Fe3+ had notable effects on the functional groups of PS and PN in EPS. The experimental results in BTFs indicate that the removal efficiency of o-DCB decreased from 100% to 56.4% for BTF1, which was not fed with RL and Fe3+, and from 100% to 80.3% for BTF2, which was fed with RL and Fe3+, when the inlet loading rate increased from 4.88 to 102 g m-3 h-1 at an empty bed residence time of 60 s. In addition, the microbial adhesive strength and the microbial community structure were different among both BTFs, highlighting the positive effects of RL and Fe3+.

Abstract
Chlorinated volatile organic compounds (Cl-VOCs) waste air is a kind of typical recalcitrant organic compounds, which poses a great threat to the ecological environment and human health. At present, the biotechnology is considered as a potential strategy for the Cl-VOCs removal due to the advantages of low energy consumption and less possibility of secondary pollution. This work summarizes the recent researches on strains, bioreactors and technology integration. The dominant pure strains for biodegradation of Cl-VOCs are first outlined with a special focus on the co-metabolism of multi-components. It then summarizes two bioreactors (optimized airlift reactor (ALR) and two-phase partitioning bioreactor (TPPB)) and strategy (addition of surfactant) for improvement of biotrickling filter (BTF), which are benefit to achieve the mass transfer enhancement in the removal of hydrophobic Cl-VOCs from waste air. After that, the integration technologies, such as magnetic field (MF)-BTF, non-thermal plasma (NTP)/ultraviolet light (UV)-BTF, and microbial electrolytic cells (MEC), are elucidated, which provide opportunities for complete mineralization of Cl-VOCs in a more efficient, energy-saving and economical way. Finally, current challenges and a perspective of future research on biotechnology for Cl-VOCs removal are thoroughly discussed.

Abstract
BACKGROUND Hospital wastewater is commonly polluted with high loads of pharmaceutically active compounds, which pass through wastewater treatment plants (WWTPs) and end up in water bodies, posing ecological and health risks. White-rot fungal treatments can cope with the elimination of a wide variety of micropollutants while remaining ecologically and economically attractive. Unfortunately, bacterial contamination has impeded so far a successful implementation of fungal treatment for real applications. RESULTS This work embodied a 91-day long-term robust continuous fungal operation treating real non-sterile hospital wastewater in an air pulsed fluidized bed bioreactor retaining the biomass. The hydraulic retention time was 3 days and the ageing of the biomass was avoided through partial periodic biomass renovation resulting in a cellular retention time of 21 days. Evolution of microbial community and Trametes abundance were evaluated. CONCLUSIONS The operation was able to maintain an average pharmaceutical load removal of over 70% while keeping the white-rot fungus active and predominant through the operation.

Abstract
Biological removal of dichloromethane (DCM) from pharmaceutical industry is limited by its recalcitrance. In this study, an airlift packing reactor (ALPR), which combined the suspended and fixed-film microbial growth system, was set up to remove DCM and co-existed toluene. The removal performance of the ALPR for DCM was greater than traditional airlift reactor (ALR). The maximum elimination capacity (ECmax) of the ALPR for DCM reached 108 g m-3 h-1 with removal efficiency (RE) of 41%, increased by 145% if compared to the ALR. The ECmax for toluene was 172 g m-3 h-1 with RE of 70%, decreased by 25% if compared to the ALR, which was mainly due to the higher liquid-phase biomass in the ALR. The results of high-throughput sequencing showed that the microbial composition on the packings of the ALPR had a large difference from its liquid-phase or the liquid-phase of the ALR. Gemmobacter, Rhizomicrobium, Chitinophaga, Vampirovibrio, and Fodinicurvata were genera with great abundance fixed on the packings and Rhizomicrobium, Chitinophaga, Vampirovibrio, and Fodinicurvata are first to be reported in VOCs biological removal. This study indicated that the ALPR can augment the microbial community and effectively improve the removal of recalcitrant VOCs.

Abstract
In this study, the effect of rhamnolipid and Mg (II) on microbial growth and 1,3-dichlorobenzene removal was investigated in two identical lab-scale biotrickling filters (named BTF1 and BTF2). The contact angle and Henry's constant were detected at various concentrations of rhamnolipid and the results indicated that rhamnolipid is able to effectively improve the solubility of 1,3-dichlorobenzene in medium. The results of the experiments in BTFs showed that the optimal concentrations of rhamnolipid and Mg (II) were 170 mg/L and 2 mg/L, respectively. The removal efficiency (RE) of 1,3-dichlorobenzene decreased from 100% to 57.13% for BTF1 that was not fed with rhamnolipid and Mg (II) and from 100% to 86.26% for BTF2 that was fed with rhamnolipid and Mg (II) when the inlet loading rate increased from 2.87 to 83.83 g/(m3 h) at an empty bed residence time (EBRT) of 60 s. The dissolved oxygen (DO) was analyzed throughout the entire period and the results showed that the two additives can significantly promote oxygen transfer. In addition, the microbial adhesive strength and community were observed and compared to show the positive role of rhamnolipid and Mg (II).

Abstract
This study employed the use of 16S rRNA gene sequence analysis to identify three of four native bacterial strains isolated from crude oil-contaminated site in Poza Rica, Veracruz, Mexico. The identified bacteria were Ochrobactrum intermedium, Pandoraea pnomenusa and Ochrobactrum sp., but SA2-09 strain was not identified. The ability of the isolates to degrade polycyclic aromatic hydrocarbons (PAHs) was evaluated at 31.61 and 54.52 mg/kg PAHs in soil, when used as crude oil in soil microcosm during 80 days of incubation at 30°C. The results demonstrated that O. intermedium biodegraded many PAHs, including the high molecular weight (HMW) PAHs fluoranthene (100% equivalent 0.24 mg/kg), benzo [b] fluoranthene (81.8% equal 0.18 mg/kg), Benzo[a]pyrene (87.0%, 0.20 mg/kg) and Benzo[g,h,i]perylene (52.7%, 0.39 mg/kg). P. pnomenusa had a degradation profile of HMW PAHs, which was similar to O. intermedium, while Ochrobactrum sp. and the strain SA-09 exhibited lower degradation rates of HMW.

Abstract
In this study, a novel Pandoraea sp. strain WL1 capable of mineralizing p-xylene as sole carbon and energy source was isolated from the activated sludge of a pharmaceutical wastewater treatment plant. A nearly complete degradation of 16.6∼99.4 mg L(-1)p-xylene in the liquid-phase was achieved within 6∼18 h accompanied by 15.9∼56.3 mg dry cell weight (DCW)L(-1) for bacterial growth. A complete pathway for p-xylene degradation by strain WL1 was presented through identification of a major intermediate (p-toluic acid) and final products (2.193 gCO2 gp-xylene(-1) of CO₂ production and 0.215 g DCW gp-xylene(-1) of bacterial yield). Kinetics of bacterial growth and p-xylene degradation were evaluated using Haldane-Andrews model and pseudo first-order model, respectively. Furthermore, a biotrickling filter (BTF) was employed to evaluate the application of strain WL1 on the removal of gas-phase p-xylene under gas flow rates of 0.41∼1.98 m(3)h(-1) for inlet loading rates of 5∼248 gm(-3)h(-1). The BTF inoculated with strain WL1 proved to be robust against fluctuations of gas flow rates and inlet p-xylene concentrations. All the results obtained highlight the potential of strain WL1 for the treatment of p-xylene.
