“…It has enabled scientists to study microbial diversity and perhaps the diversity of the community (Guerra et al, 2018). Most of the current studies regarding the search for oil-degrading bacteria have included 16s rRNA gene sequencing in the protocol which uses the differences in the sequences in the regions of the highly conserved 16s rRNA gene that encodes the smaller subunit of the bacterial ribosome to identify bacteria (Kim et al, 2018;Gao et al, 2021;Yu et al, 2022). Analyzing the sequences enables scientists to link the potential oil-degrading bacterium they have found to any well-studied bacteria and gain insights into its biology (David and Berry, 2017).…”

The petrochemicals produced from refining oil have become a large part of human life, making oil a valuable and expensive commodity. As a non-renewable resource, extraction and transport efforts have intensified to keep up with the demand, increasing the occurrences of oil spills. Such accidents have devastating impacts on the environment, the health of organisms, and a country's economy like the Philippines, and thus, need to be resolved immediately. One way to deal with oil spills is through bioremediation but the process is still facing several challenges. For one, the toolbox for bioremediation is limited. About 79 genera of bacteria were observed to degrade oil but there are only a small number of bacterial species and/or strains that have been recognized as useful for bioremediation. Second is that most oil-degrading bacteria found have low oil degradation efficiencies. Another challenge is keeping the bacteria alive to carry out the process. Fortunately, progress has been made in solving these challenges. Researchers are now testing different consortia, including bacteria–bacteria, bacteria–fungi, bacteria–microalgae, that can complement each other such as biosurfactant-producing bacteria with different oil-degrading microorganisms or microalgae or fungi that enhance the growth of oil-degrading bacteria. A consortium like this improves the survivability of each microorganism and enhances the oil-degrading efficiency. Moreover, the search for additional oil-degrading and biosurfactant-producing bacteria and other microorganisms to add to the bioremediation toolbox has been improved with the emergence of high-throughput sequencing. Aside from microorganisms, seaweeds have shown potential for bioremediation. The seaweed Caulerpa prolifera has been demonstrated to degrade diesel up to a certain concentration with the help of the bacteria growing on its surface. Bioremediation has a long way to go, but recent developments have shown promise and it remains to be the cheapest, most environment-friendly, and most effective way of dealing with oil spills.

“…Although a large number of microorganisms with PAH degradation ability have been isolated and identified, 99% of potential hydrocarbon degraders are yet to be discovered in nature, and the adaptability of artificial MMS would be further improved by expanding the scope of strain discovery. Currently, molecular sequencing technology and bioinformatics are regarded as useful tools to explore the relationship of inter-bacterial interaction, such as mutualism and competition, and its impact on the compatibility within the artificial MMS (Yu et al, 2022 ).…”

Polycyclic aromatic hydrocarbons (PAHs) are environmental pollutants with major risks to human health. Biological degradation is environmentally friendly and the most appealing remediation method for a wide range of persistent pollutants. Meanwhile, due to the large microbial strain collection and multiple metabolic pathways, PAH degradation via an artificial mixed microbial system (MMS) has emerged and is regarded as a promising bioremediation approach. The artificial MMS construction by simplifying the community structure, clarifying the labor division, and streamlining the metabolic flux has shown tremendous efficiency. This review describes the construction principles, influencing factors, and enhancement strategies of artificial MMS for PAH degradation. In addition, we identify the challenges and future opportunities for the development of MMS toward new or upgraded high-performance applications.

“…Bio-remediation is seen to be environmental friendly and sustainable when compared to the use of chemical compounds for crude oil spill clean-up. Studies have shown several researchers carrying out bio-remediation of crude oil spillage using individual microorganisms or organic amendments like compost, poultry droppings, cow dung for bioaugmentation which in turn drives the bioremediation process Marie et al, 2020;Yu et al, 2022). These studies have shown the individual capacities of various microorganisms in bioremediation of crude oil polluted soils, their mechanisms for crude oil degradation and kinetics behind their degradation capacities.…”

“…This led to the need to study the ecological succession of these microorganisms to help identify the predominant organisms, transient organisms and also the most persistent indigenous organisms that drive the bio-remediation process. Yu et al (2022) monitored the bacterial succession of crude oil enriched soil using next generation sequencing so as to identify even unculturable organisms that may have participated in the bioremediation. This present study carried out bio-remediation of hypertoxic crude oil concentration using the following amendments: wood chip, poultry droppings, saw dust, saw dust and N.P.K.…”

Dangerous impact of crude oil in the environment is a common knowledge and its spillage has been controlled using both chemical and biological methods. Bioremediation however, is most advocated because of its environmental friendliness and sustainability. The present study sought to identify and monitor successions, and diversity of microorganisms elicited by five amendments in the bioremediation of hypertoxic crude oil pollution. Five amendment patterns which incorporated 200 g each of saw dust, wood chip, compost, N.P.K. fertilizer and poultry droppings; were used to stimulate biodegradation in 50% crude oil contaminated soil, and their respective microbial counts and microbial successions were monitored over a period of eight months. Statistical analyses were conducted using SPSS version 21 software. Poultry droppings amendment had the highest significant (p<0.05) bacterial and fungal counts. Bacillus subtilis, Stenotrophomas maltophilia and Pseudomonas aeruginosa were the predominant bacteria observed during the microbial succession studies across the amendment microcosms, while Aspergillus flavus, Penicillium citrinnum and Fusarium solani were the predominant fungal isolates. It was observed that the hyper-toxic concentration of the crude oil impacted the diversity and succession of the microbes across all the amendments used when compared to the control sample.
