“…In this process, bacteria use the hydrocarbons as carbon and energy source. 1,7 Several examples of bacteria are reported for their ability to degrade diesel, 8 such as Rhodococcus sp., 9 Pseudomonas sp., 9 Acinetobacter sp., 10 Bacillus and Alcanivorax ; 11 in the latter case, bacteria produce biosurfactants that increase the solubility of diesel in water facilitating the bioremediation process. 11 …”

“…These include species in the genera Achromobacter, Bacillus, Enterobacter, Escherichia, Gordona, Mycobacterium, Pseudomonas, Rhodococcus, Serratia and Staphylococcus [3, 13, 14 15, 16]. Bioremediation procedures involving the exploitation of degradative ability of microorganism, via bioaugmentation, nutrient application and alteration of environmental factors, has become a veritable approach to clean up of aquatic environments and marine ecosystems [17,18,19,20,21].…”

Introduction: hydrocarbon contamination of surface waters as a result of anthropogenic activity poses threat to ecosystems and counter their beneficial uses. Some indigenous microbial communities have the potential to purify such waters unaided. Aims: To show the biodegradative potential of microbial communities in Lagos and Ologe Lagoons during minimal pollution with crude oil. Materials and Methods: The total heterotrophic bacteria and hydrocarbon utilising bacterial and fungal populations were estimated from Lagos and Ologe lagoon water samples contaminated with 1% crude oil over 42-day incubation period by plate count and vapour-phase transfer techniques. Residual hydrocarbons were determined by Gas chromatography. Results: The predominant bacterial genera identified from the lagoons include Enterobacter, Klebsiella and Proteus, while Escherichia, and Morganella. Aspergillus and Mucor were the predominant fungal genera in both waters. The hydrocarbon degradation rate in the Lagos Island microcosm was 65.391±0.370 mg/l/d, degradation rate constant 0.05±0.01 /d, half-life 9.559±0.093 /d and percentage degradation of 95.315 ± 0.134. Corresponding values in the Ologe water were 61.190± 8.542 mg/l/d, 8.725 ±0.389 /d, 0.055±0.003/d and 96.345±0.488 respectively. There was almost complete disappearance of the various fractions of the oil in the two samples. The microbial communities from both lagoons effectively utilised majority of the hydrocarbon fractions after 42 days where 66.890±1.075 and 100±000 were recorded for benzene, toluene had 100±000 percent degradation, anthracene 96.755±0.119 and 99.726±0.026, and pristane had 91.674±0.222 and 99.943±0.015 while phytane had 96.44±0.058 and 99.670±0.104 respectively. Conclusion: Efficient biodegradation of moderate contamination crude oil could be achieved by indigenous microbial flora present in Lagos and Ologe lagoon waters.

Green surfactants–based bioremediation of polycyclic aromatic hydrocarbons (PAHs) from the environment is a promising technique. Rhamnolipids are a class of glycolipid surfactants that belong to the category of green surfactants and have distinctive characteristics. PAHs, which are hazardous toxins, are commonly found in polluted soil, water, and air. PAHs are difficult to break down because they are resistant to degradation and typical methods of cleaning up pollution are not very effective. In recent years, there has been a growing interest in the capacity of specific microorganism species to produce rhamnolipids, which can enhance the process of PAH biodegradation. Rhamnolipids can dissolve and enhance the accessibility of PAHs, thereby boosting the effectiveness of microorganisms that break down PAHs. The presence of rhamnolipids can be attributed to the equilibrium between hydrophobic and hydrophilic properties, as well as their positive charge. Rhamnolipids have biosurfactant properties, making them beneficial for the bioremediation of polluted soil and water. In general, rhamnolipids have proven to be a highly efficient means of removing PAHs from the environment, providing a viable alternative to conventional chemical approaches. Nevertheless, additional investigation is necessary to gain a deeper comprehension of the fundamental principles behind rhamnolipid‐assisted bioremediation and to enhance its implementation in larger real‐world scenarios. This study provides a concise overview of recent research on the utilization of rhamnolipids for bioremediating PAHs in the environment. The article covers the underlying mechanisms, the specific microorganisms employed, and the overall efficacy of the bioremediation process. The utilization of rhamnolipids as a bioremediation tool is examined, along with the difficulties and restrictions of its implementation. The review's conclusion is followed by a discussion on the future directions for studying this topic.
