Summary: This study isolated multifunctional rhizobacteria from different sources, such as rhizosphere soils and crude oil sludge, and found that these bacteria can efficiently degrade hydrocarbons while producing biosurfactants. The presence of biosurfactants was confirmed by SEM images, showing the formation of exopolymers that enhance the degradation process.

Summary: This study investigated the crude oil degrading capabilities of biosurfactant-producing strains of Pseudomonas aeruginosa and Meyerozyma sp. The biosurfactants produced by these strains showed high emulsification activities in crude oil and stability under various conditions. Gravimetric and GC-MS analyses demonstrated efficient petroleum hydrocarbons degradation by both strains, indicating their potential for bioremediation of hydrocarbons-contaminated sites.

Summary: Waxy crude oil is a concern in the oil and gas industry due to wax deposition in pipelines. Traditional chemical solutions are not environmentally friendly, so the biodegradation approach is explored as an alternative. A study on 11 thermophilic bacteria showed high hydrocarbon degradation ability, but it is believed that multiple species are needed for the degradation of paraffin wax. Five consortia were developed based on the efficiency of these bacteria, with Consortium 3 showing the highest degradation and dominance of Geobacillus, Parageobacillus, and Anoxybacillus genera.

Summary: A greenhouse experiment was conducted to evaluate the effect of phytoremediation and biochar application on hydrocarbon degradation in crude oil-contaminated soils. The experiment involved four levels of biochar application (0, 5, 10, and 15 t/ha) and the presence or absence of Vigna unguiculata (cowpea; +C, -C), replicated three times in a 4 x 2 x 3 factorial design. The results showed that the highest degradation efficiency of 69.2% (7033 mg/kg) was achieved in contaminated soils amended with 15 t/ha biochar after 60 days of incubation. Significant interactions were observed between biochar x plant and biochar x days. Biochar also enhanced plant growth in contaminated soils.

Summary: This study investigated the distribution of PAH degraders at two different petroleum hydrocarbon-polluted sites in the Niger Delta and demonstrated the ability of indigenous microbes to utilize these PAHs. The findings suggest that these indigenous microbes can be used to effectively remove PAHs from oil-polluted soils through bioremediation.

Summary: The cold-adapted mixed culture JY isolated from alpines meadow soil showed the capability to degrade 53.68% of total petroleum hydrocarbons under low temperature, with a preference for degrading alkanes over polycyclic aromatic hydrocarbons and other polar components. The study also found a shift in bacterial composition during the degradation process, from alkane degraders to PAH degraders within the mixed flora.

Summary: Petroleum contamination in marine environments causes serious harm to ecosystems, but bioremediation with immobilized microorganisms shows promise for oil-polluted environments. In this study, Bacillus licheniformis was immobilized in Ca alginate beads for oil biodegradation, with optimized variables leading to higher degradation rates compared to freely suspended cells. The effectiveness of the process variables differed between free and immobilized cell systems, with immobilized cells showing greater potential for crude oil degradation.

Summary: Microbial degradation of recalcitrant hydrocarbons is crucial for remediation of oil and gas-contaminated environments. Study showed that Tenax-TA can effectively trap both microorganisms and hydrocarbons for assessing hydrocarbon-degrading microorganisms of interest. Various adsorbent materials were evaluated, and Tenax-TA recovered the highest diversity of microbial taxa in contaminated groundwater.
