Petroleum Hydrocarbon-Degrading Bacteria for the Remediation of Oil Pollution Under Aerobic Conditions: A Perspective Analysis

Abstract

With the sharp increase in population and modernization of society, environmental pollution resulting from petroleum hydrocarbons has increased, resulting in an urgent need for remediation. Petroleum hydrocarbon-degrading bacteria are ubiquitous in nature and can utilize these compounds as sources of carbon and energy. Bacteria displaying such capabilities are often exploited for the bioremediation of petroleum oil-contaminated environments. Recently, microbial remediation technology has developed rapidly and achieved major gains. However, this technology is not omnipotent. It is affected by many environmental factors that hinder its practical application, limiting the large-scale application of the technology. This paper provides an overview of the recent literature referring to the usage of bacteria as biodegraders, discusses barriers regarding the implementation of this microbial technology, and provides suggestions for further developments.

Isolation and Characterization of Biosurfactant-Producing Bacteria From Oil Well Batteries With Antimicrobial Activities Against Food-Borne and Plant Pathogens

“…Furthermore, our results are in agreement with previous reports on microbial diversity in other oil well reserves (Lenchi et al, 2013;Xiao et al, 2016). The biosurfactant-producing bacteria identified in this study (Bacillus, Streptomyces, Microbacterium Pseudomonas, Arthrobacter, Rhodococcus and Micrococcus) belong to genera that have also been identified in a wide range of studies as crude oil degraders and biosurfactant producers (Wu et al, 2008;Brooijmans et al, 2009;Korenblum et al, 2012;Obi et al, 2016;Parthipan et al, 2017;Xu et al, 2018). In follow-up studies, the oil-spreading and drop collapse assays allowed for confirmation and initial ranking of our isolated biosurfactant producers (Santos et al, 2016).…”

Deep Hypersaline Anoxic Basins as Untapped Reservoir of Polyextremophilic Prokaryotes of Biotechnological Interest

“…Indeed, many studies have focused their attention on hydrocarbon-degrading bacteria in oil-rich environments, including oil spill areas and oil reservoirs [257], and have demonstrated that their abundance is closely related to the respective types of petroleum hydrocarbons and surrounding environmental factors [258][259][260][261]. Despite this, many other normal and extreme microorganisms have been isolated and employed as biodegraders for dealing with petroleum hydrocarbons, representing a promising biotechnological alternative for achieving oil-hydrocarbon degradation [9,262]. Because of the particular physiological characteristics of microorganisms isolated from extreme environments, including DHABs, prokaryotes can be employed for enhanced bioremediation of oil hydrocarbons, especially in hypersaline environments [263,264].…”

The role of marine microorganisms in offshore pollution remediation

“…Bioremediation is a comprehensive good way and necessary means to prevent and control Marine environmental pollution and Marine ecosystem dysfunction . It was low cost, less side-effects, No secondary pollution， However, due to the complexity of the causes of offshore pollution, different bioremediation schemes should be adopted for different pollutants (Xu, Liu et al 2018). Successful bioremediation technology would be built on a set of data analyses, there are three main factors: 1) the type of pollutant; 2) degradable microorganisms; 3) relevant environmental factors (Teng and Chen 2019).…”
