Abstract Bacterial strains of the genera Arthrobacter , Bacillus Dietzia Kocuria and Micrococcus were isolated from oil-contaminated soils Balgimbaev, Dossor, Zaburunye oil fields in Kazakhstan. They selected 1376 based on their unique ability to use crude polyaromatic hydrocarbons (PAHs) as sole source carbon energy growth experiments. The degraded a wide range aliphatic aromatic components generate total 170 acid metabolites. Eight metabolites detected during degradation anthracene phenanthrene, two which led description new pathway. bacterial bussei/agilis SBUG 2290, atrophaeus 2291, subtilis 2285, kunjamensis 2289, rosea 2287, polaris 2288, luteus 2286 promoted barley shoots roots soil, demonstrating enormous potential isolatable cultivable soil bacteria remediation.

Characterization and identification of long-chain hydrocarbon-degrading bacterial communities in long-term chronically polluted soil in Ogoniland: an integrated approach using culture-dependent and independent methods

Environmental Science and Pollution Research, Journal Year: 2024, Volume and Issue: 31(21), P. 30867 - 30885

Published: April 15, 2024

Escalating oil consumption has resulted in an increase accidental spills of petroleum hydrocarbons, causing severe environmental degradation, notably vulnerable regions like the Niger Delta. Complex mixture these hydrocarbons particularly long-chain alkanes presents unique challenges restoration polluted environment due to their chemical properties. This study aimed investigate hydrocarbon-degrading bacterial communities within long-term chronically soil Ogoniland, by utilizing both traditional cultivation methods and modern culture-independent techniques. Results revealed that surface-polluted (SPS) subsurface (SPSS) exhibit significantly higher total organic carbon (TOC) ranging from 5.64 5.06% (TPH) levels 36,775 ppm 14,087 ppm, compared unpolluted (UPS) with 1.97% TOC 479 TPH, respectively. Analysis chain lengths reveals prevalence longer-chain (C20-28) surface soil. Culture-dependent methods, crude enrichment (COE) paraffin wax (PWE), yield 47 isolates subjected a alkane degradation assay. Twelve strains demonstrate significant abilities across all enriched media. Three members, namely Pseudomonas sp. (almA), Marinomonas Alteromonas (ladA), genes responsible for demonstrating efficiency between 50 80%. Culture-independent analysis SPS samples greater species richness diversity SPSS samples. Proteobacteria dominates as phylum sample types, 22.23 82.61%, Firmicutes (0.2-2.22%), Actinobacteria (0.4-3.02%), Acidobacteria (0.1-3.53%) also prevalent. Bacterial profiles at genus level distinct variations among populations comprising number hydrocarbon degraders functional predictions highlight presence potential catabolic (nahAa, adh2, cpnA) However, culture-dependent only captured few dominant members found analysis, implying more specialized media or environments are needed isolate members. The findings this contribute valuable information ecological biotechnological aspects, aiding development effective bioremediation applications restoring oil-contaminated environments.

Overview of petroleum hydrocarbon pollution and bioremediation technologies

Bioremediation Journal, Journal Year: 2024, Volume and Issue: unknown, P. 1 - 23

Published: June 9, 2024

An exceptional rise in population, urbanization and human activities associated with modernization has increased pollutants to critical levels. These are different shades across sectors however, petroleum hydrocarbon is one of the most significant. This because it comprises thousands various chemicals structural behavioral differences causing widespread distribution into environment, bioaccumulation biological systems, harmful effects on living organisms resistance biodegradation. Hydrocarbon pollution mainly attributed anthropogenic from crude oil refineries, sabotage pipelines, industries other sources consequently negatively impacts all environmental compartments: air, water, land, sediments sometimes groundwater deleterious effects. By extension, also contributes public health risks which supports need for an effective remediation option. Bioremediation been considered a highly functional option selective advantages such as: sustainability, cost-effectiveness, less complex technology eco-friendly attributes compared invasive methods. There approaches bioremediation more recently use biosurfactants immobilized cells have introduced as alternatives. Regardless, important understand mechanisms factors that biodegradation choice technique depends them. review therefore describes composition behavior hydrocarbons environment highlights their activity.

Published: Feb. 5, 2025

Since the beginning of their production and use, fossil fuels have affected ecosystems, causing significant damage to biodiversity. Bacterial bioremediation can provide solutions this environmental problem. In study, new species Isoptericola peretonis sp. nov. 4D.3 T has been characterized compared other closely related in terms hydrocarbon degradation biosurfactant by vitro silico analyses. Biosurfactants play an important role microbial emulsifying hydrocarbons making them accessible machinery. The tests performed showed positive results a greater or lesser degree for all strains. synthesis biosurfactants, strains tested activity three complementary assays (CTAB, hemolysis E 24 %) rhamnolipid genes predicted majority Regarding degradation, analyzed presented putative responsible aerobic anaerobic aromatic alkane hydrocarbons. Overall, our highlight metabolic diversity biochemical robustness genus which is proposed be interest field bioremediation.
