JOURNAL OF ENVIRONMENTAL MANAGEMENT 2024; 351:119937. [PMID: 38159304 DOI: 10.1016/j.jenvman.2023.119937] [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: 08/18/2023] [Revised: 11/12/2023] [Accepted: 12/23/2023] [Indexed: 01/03/2024]
Abstract
Petroleum hydrocarbon (PHC) degrading bacteria have been frequently discovered. However, in practical application, a single species of PHC degrading bacterium with weak competitiveness may face environmental pressure and competitive exclusion due to the interspecific competition between petroleum-degrading bacteria as well as indigenous microbiota in soil, leading to a reduced efficacy or even malfunction. In this study, the diesel degradation ability and environmental robustness of an endophytic strain Pseudomonas aeruginosa WS02, were investigated. The results show that the cell membrane surface of WS02 was highly hydrophobic, and the strain secreted glycolipid surfactants. Genetic analysis results revealed that WS02 contained multiple metabolic systems and PHC degradation-related genes, indicating that this strain theoretically possesses the capability of oxidizing both alkanes and aromatic hydrocarbons. Gene annotation also showed many targets which coded for heavy metal resistant and metal transporter proteins. The gene annotation-based inference was confirmed by the experimental results: GC-MS analysis revealed that short chain PHCs (C10-C14) were completely degraded, and the degradation of PHCs ranging from C15-C22 were above 90% after 14 d in diesel-exposed culture; Heavy metal (Mn2+, Pb2+ and Zn2+) exposure was found to affect the growth of WS02 to some extent, but not its ability to degrade diesel, and the degradation efficiency was still maintained at 39-59%. WS02 also showed a environmental robustness along with PHC-degradation performance in the co-culture system with other bacterial strains as well as in the co-cultured system with the indigenous microbiota in soil fluid extracted from a PHC-contaminated site. It can be concluded that the broad-spectrum diesel degradation efficacy and great environmental robustness give P. aeruginosa WS02 great potential for application in the remediation of PHC-contaminated soil.

The proliferation and colonization of functional bacteria on amorphous polyethylene terephthalate: Key role of ultraviolet irradiation and nonionic surfactant polysorbate 80 addition. CHEMOSPHERE 2022; 291:132940.

Abstract
Environmental pollution with plastics including polyethylene terephthalate (PET) has become a severe global problem, especially microplastic pollution, which is acknowledged as an emerging global pollutant. Biodegradation as a feasible and promising method has been studied, while colonization as the initiating step of the degradation process has seldom been studied. Here in this paper, we explored for the first time the key role of ultraviolet (UV) irradiation and nonionic surfactant polysorbate 80 (Tween-80, 0.2% V/V) in the proliferation and colonization of three functional bacteria (Pseudomonas putida, Pseudomonas sp. and Paracoccus sp.) on amorphous PET (APET). We found that 25 days of UV irradiation can trigger photolytic degradation process (appear the stretching vibration of associating carboxyl end group and the in-plane bending vibration of -OH) and introduce oxygen-containing functional groups on the surface of APET, even though the hydrophobicity of APET was scarcely changed. With regard to Tween-80, it can be utilized by these bacteria strains as carbon source to promote the proliferation, and it can also improve the cell surface hydrophobicity to stimulate the bacterial colonization during the first ten days of the experiment. When UV-irradiation and Tween-80 were provided together, the former factor can provide the target sites for functional bacteria to colonize, and the later factor can provide more candidates waiting to colonize by stimulating proliferation. As a result, an even better proliferation and colonization result can be achieved through the synergistic effect between the two factors. To some extent, the exposure between potential degrading bacteria and substrates to be degraded can be increased, which will create conditions for degrading. Generally, this research can provide certain theoretical basis and technical guidance for the remediation of plastic-polluted soil and the ocean.

Use of carbon steel ball bearings to determine the effect of biocides and corrosion inhibitors on microbiologically influenced corrosion under flow conditions.

Abstract
A consortium of sulfate-reducing bacteria consisting mostly of Desulfovibrio, Desulfomicrobium, and Desulfocurvus from oil field produced water was cultivated in a chemostat, receiving medium with 20 mM formate and 10 mM sulfate as the energy and 1 mM acetate as the carbon source. The chemostat effluent, containing 5 mM sulfide and 0.5 mM of residual acetate, was passed through 1-ml syringe columns with 60 carbon steel ball bearings (BBs) of 53.6 ± 0.1 mg each at a flow rate of 0.8 ml/h per column. These were treated every 5 days with 1.6 ml of 300 ppm of glutaraldehyde (Glut), tetrakis(hydroxymethyl)phosphonium sulfate (THPS), benzalkonium chloride (BAC), or Glut/BAC, a mixture of Glut and BAC. Alternatively, BBs were treated with 33% (v/v) of a water-soluble (CR_W) or an oil-soluble (CR_O1 or CR_O3) corrosion inhibitor for 20 s after which the corrosion inhibitor was drained off and BBs were packed into columns. The effluent of untreated control columns had no acetate. Treatment with the chemically reactive biocides Glut and THPS, as well as with Glut/BAC, gave a transient increase of acetate indicating decreased microbial activity. This was not seen with BAC alone indicating it to be the least effective biocide. Relative to untreated BBs (100%), those treated periodically with Glut, THPS, BAC, or Glut/BAC had a general weight loss corrosion rate of 91, 81, 45, and 36% of the untreated rate of 0.104 ± 0.004 mm/year, respectively. Single treatment with corrosion inhibitors decreased corrosion to 48, 2, and 1% of the untreated rate for CR_W, CR_O1 and CR_O3, respectively. Analysis of the distribution of corrosion rates from the weight loss of individual BBs (N = 120) indicated the presence of a more slowly and a more rapidly corroding group. BAC treatment prevented emergence of the latter, and this quaternary ammonium detergent appeared most effective in decreasing corrosion not because of its biocidal properties, but because of its corrosion inhibitory properties.

Abstract
Proper preservation of microbial activity over long periods poses a considerable challenge for pollutant biopurification. A composite microbial agent, mainly composed of bacteria and fungi isolated by the current research team, was constructed in this study and its performance in the removal of mixed waste gases (containing α-pinene, n-butyl acetate and o-xylene) was investigated. According to the removal efficiency in the first 24h and the response to starvation, the optimal ratio of selected carriers (activated carbon, wheat bran and sawdust) was found to be 1:2:1. In some cases of storages, the removal capability of the microbial agent was more than twice that of the suspension. Microbial analysis showed that the inoculated bacterial and fungal strains dominated the agent preparation and utilization. These results indicated that the agent has potential for use in biopurification of mixed waste gas, favoring the reduction of environmental passives and longer retention of microbial activity.

Abstract
Environmentally ubiquitous bacteria such as Pseudomonas aeruginosa evolved mechanisms to adapt and prevail under diverse conditions. In the current investigation, strains of P. aeruginosa demonstrating high rates of crude oil utilization and tolerance to high concentrations of heavy metals were found in both crude oil-contaminated and uncontaminated sites in Kuwait, and were dominant in the contaminated sites. The incidence of P. aeruginosa in tested soils implies the definitive pattern of crude oil contamination in the selection of the bacterial population in petroleum-contaminated sites in Kuwait. Surprisingly, the unculturable P. aeruginosa in different soil samples showed significant high similarity coefficients based on 16S-RFLP analyses, implying that the unculturable fraction of existing bacterial population in environmental samples is more stable and, hence, reliable for phylogenetic studies compared to the culturable bacteria.

Abstract
Pseudomonas aeruginosa is well known for its ability to form biofilm on indwelling medical devices. These biofilms are difficult to remove because of their high tolerance to conventional antibiotics. Therefore, there is a need to look for alternative agents such as medicinal plants, which can eradicate or inhibit biofilm effectively. This study evaluated the role of neem in inhibiting biofilm formation by P aeruginosa Factors contributing to adherence and biofilm formation were also studied. Results demonstrated that neem leaves extract was quite effective in disrupting formation and structure of biofilms. Moreover, the level of exopolysaccharide, alginate, hydrophobic interactions and uroepithelial cell attachment, which contributes to biofilm formation, was also affected significantly. Results confirm the effectiveness of neem extract in inhibiting biofilm formation. Such studies can lead to the discovery of safe antimicrobial drugs from natural sources without the risk of resistance.

Abstract
Twelve different bacteria-yeast combinations were tested for determination of their ability to biodegrade diesel oil. The cell surface properties of the bacterial and yeast strains were correlated with the type of carbon source used in the experiments. The highest biodegradation of diesel oil after 7 days was obtained for the following combinations: Aeromonas hydrophila MR4-Yarrowia lipolytica EH 56 (87 %) and Xantomonas maltophila MRP7-Candida maltosa EH15 (90 %). Degradation performances of 10 of 12 combinations were enhanced by the presence of rhamnolipids. The highest increases were observed for A. hydrophila MR4-C. maltosa EH15 (from 34 to 67 %), A. hydrophila MR4-C. maltosa EH60 (from 47 to 76 %) and for Pseudomonas stutzeri MR7-C. maltosa EH60 (from 29 to 79 %). The addition of rhamnolipids to the system reduces the removal time of diesel oil from the contaminated water and changes the microbial adhesion to hydrocarbons. Modification of the cell surface of the tested strain during biodegradation is a very important factor determining the removal of hydrophobic compounds.

Abstract
We review the environmental role of rhamnolipids in terms of microbial life and activity. A large number of previous research supports the idea that these glycolipids mediate the uptake of hydrophobic substrates by bacterial cells. This feature might be of highest priority for bioremediation of spilled hydrocarbons. However, current evidence confirms that rhamnolipids primarily play a role in surface-associated modes of bacterial motility and are involved in biofilm development. This might be an explanation why no direct pattern of hydrocarbon degradation was often observed after rhamnolipids supplementation. This review gives insight into the current state of knowledge on how rhamnolipids operate in the microbial world.
