In the recent era, increasing persistence of hazardous contaminants is badly affecting globe in many ways. Due to high environmental contamination, almost every second species on earth facing worst issue their survival. Advances newer remediation approaches may help enhance bioremediation's quality, while conventional procedures have failed remove compounds from environment. Chemical and physical waste cleanup been used current circumstances; however, these methods are costly harmful Thus, there has a rise use bioremediation due an increase which led development genetically engineered microbes (GEMs). It safer more cost-effective microorganisms rather than alternative methods. GEMs created by introducing stronger protein into bacteria through biotechnology or genetic engineering desired trait. Biodegradation oil spills, halobenzoates naphthalenes, toluenes, trichloroethylene, octanes, xylenes etc. accomplished using such bacteria, fungus, algae. Biotechnologically induced powerful naturally occurring ones degrade faster because they can quickly adapt new pollutants encounter co-metabolize. Genetic worthy process that will benefit environment ultimately health our people.

Oil spills are a global challenge, contaminating the environment with organics and metals known to elicit toxic effects. Ecosystems within Nigeria's Niger Delta have suffered from prolonged severe for many decades but level of impact on soil microbial community structure potential contaminant bioremediation remains unclear. Here, we assessed extent/impact an oil spill in this area 6 months after accident both community/diversity distribution polycyclic aromatic hydrocarbon ring-hydroxylating dioxygenase (PAH-RHDGNα) genes, responsible encoding enzymes involved degradation PAHs, across impacted area. Analyses confirmed presence contamination, including such as Cr Ni, whole at depth. The contamination composition, resulting lower diversity all contaminated soils. Gamma-, Delta-, Alpha- proteobacteria Acidobacteriia dominated 16S rRNA gene sequences area, while Ktedonobacteria non-contaminated PAH-RHDαGN genes were only detected highlighting clear relationship contamination/hydrocarbon metabolism. Correlation analysis indicated significant positive relationships between contaminants (organics, Ni), gene, bacteria/archaea Anaerolinea, Spirochaetia Bacteroidia Thermoplasmata, Methanomicrobia, Methanobacteria indicating that not present, microbes depth potentially playing important role degrading present. These findings provide new insights remaining spill, its impacts indigenous communities their situ Delta's ecosystem. It highlights strength using cross-disciplinary approach assess extent pollution single study.

The complexity of crude oil composition, combined with the fluctuating oxygen level in contaminated environments, poses challenges for bioremediation pollutants, because compound-specific microbial degradation petroleum hydrocarbons under certain conditions. As a result, facultative bacteria capable breaking down both aerobic and anaerobic conditions are presumably effective, however, this hypothesis has not been directly tested. In current investigation,

Deep-sea environments are featured by low temperature and high hydrostatic pressure, which inhibits petroleum hydrocarbon metabolism microorganisms. Herein, we developed novel bioremediating agents composed of different combinations Pseudomonas zhaodongensis dimethylsulfoniopropionate (DMSP) to promote oil degradation at deep-sea microcosm environment. First, through transcriptome sequencing, revealed DMSP might provide pressure protection via secretion potential piezolytes within the cell, let bacteria healthy growth thereby promoted biodegradation. Then, measurement high-throughput assessed effectiveness on using studied indigenous microorganism (i.e., natural remediation) restore oil-contaminated muddy sandy sediments microcosm, demonstrated: 1) Oil efficiency among treatments was 23.47 % – 41.02 higher than that in remediation; 2) Each remediation plan defined specialized bacterial community. Marinobacter, Idiomarina, Sulfitobacter, Ferrimonas, Halodesulfovibrio, Paramaledivibacter were keystone oil-degrading taxa; 3) Overall, microbial community sediment samples treated bioremediation obtained better diversification trophic interactions, structure stability interference resistance; 4) Compared remediation, pathways involving component biogeochemical cycling exhibited varying degrees up-regulation agent-treated groups. Altogether, these results emphasize crucial role P. enhancing oil-polluted typical condition, a idea for in-situ restoration pollution deep sea future.
