“…High oil concentrations inhibited Alcanivorax, due to the high concentration of oil, mainly alkanes and PAHs. Bacosa et al [123] also reported that the biodegradation rates of alkanes, as determined by first-order kinetics, decreased with increasing oil concentration. The percent residual remained constant at 50% regardless of the initial engagement.…”

“…Alkanes can be harmful at high doses and impede the growth of some microorganisms or beneficial to other bacteria. The structure of the microbial community can change as the dominant degraders of hydrocarbons or their metabolites outcompete others, which cannot break down at greater oil concentrations [123]. High oil concentrations inhibited Alcanivorax, due to the high concentration of oil, mainly alkanes and PAHs.…”

Over the past century, the demand for petroleum products has increased rapidly, leading to higher oil extraction, processing and transportation, which result in numerous oil spills in coastal-marine environments. As the spilled oil can negatively affect the coastal-marine ecosystems, its transport and fates captured a significant interest of the scientific community and regulatory agencies. Typically, the environment has natural mechanisms (e.g., photooxidation, biodegradation, evaporation) to weather/degrade and remove the spilled oil from the environment. Among various oil weathering mechanisms, biodegradation by naturally occurring bacterial populations removes a majority of spilled oil, thus the focus on bioremediation has increased significantly. Helping in the marginal recognition of this promising technique for oil-spill degradation, this paper reviews recently published articles that will help broaden the understanding of the factors affecting biodegradation of spilled oil in coastal-marine environments. The goal of this review is to examine the effects of various environmental variables that contribute to oil degradation in the coastal-marine environments, as well as the factors that influence these processes. Physico-chemical parameters such as temperature, oxygen level, pressure, shoreline energy, salinity, and pH are taken into account. In general, increase in temperature, exposure to sunlight (photooxidation), dissolved oxygen (DO), nutrients (nitrogen, phosphorous and potassium), shoreline energy (physical advection—waves) and diverse hydrocarbon-degrading microorganisms consortium were found to increase spilled oil degradation in marine environments. In contrast, higher initial oil concentration and seawater pressure can lower oil degradation rates. There is limited information on the influences of seawater pH and salinity on oil degradation, thus warranting additional research. This comprehensive review can be used as a guide for bioremediation modeling and mitigating future oil spill pollution in the marine environment by utilizing the bacteria adapted to certain conditions.

“…HTCC1062 metabolizes isoprene, acetone, acetaldehyde, DMS, and cyclohexanol, which are some of the most well-studied VOCs for their roles in sea-air exchange and atmospheric chemistry 18 . BTEX are produced by some algae 19 , and are growth substrates for a wide variety of bacteria isolated from oilfields 22,23 , soils 24 , groundwater 25 , and wastewater 26 . Less is known about BTEX consumption by marine bacteria, which is likely an important sink that limits BTEX emissions into the atmosphere 27 .…”

Labile dissolved organic carbon (LDOC) in the oceans accounts for ∼ ¼ of global photosynthesis and turns over with a half-life of about one day, fueling one of the largest engines of microbial heterotrophic production on the planet. Volatile organic compounds (VOCs) are poorly constrained components of LDOC. We detected 78 VOCs totaling 18.5 μM in cultures of the model diatomPhaeodactylum tricornutum, including hydrocarbons usually found in petroleum. In five individual cocultures with bacteria adapted to grow with this diatom, 1 to 66 VOCs were depleted. Two of the most active VOC consumers,MarinobacterandRoseibium,had more VOC oxidation genes, and attached to the diatom, suggesting VOC specialism. Diatom photosynthesis increased by up to 29% in the presence of VOC consumers, indicating that VOC consumption by heterotrophic bacteria in the phycosphere – a region of rapid organic carbon oxidation that surrounds phytoplankton cells – could impact global rates of primary production.

“…Bioremediation is an cost-effective and eco-friendly approach to remove pollutants from the environment. Many microorganisms are capable to degrade BTEX under aerobic conditions, including Acidocella (Eze 2021 ), Pseudomonas, Burkholderia, Cupriavidus ( Bacosa et al 2021 ), Streptomyces (Hocinat et al 2020 ), Acinetobacter (Zhou et al 2016 ), Comamonas ( Jiang et al 2015 ), Bacillus (Wongbunmak et al 2020 ), Microbacterium (Wongbunmak et al 2017 ), Massilia (Son et al 2021 ), Paraburkholderia (Lee et al 2019 ), Variovorax (Benedek et al 2021 ), Rhodococcus (Orro et al 2015 ). The stability of the aromatic hydrocarbon is the biggest common challenge for organisms to acquire and utilize.…”

Petroleum hydrocarbon contamination is of environmental and public health concerns due to its toxic components. Bioremediation utilizes microbial organisms to metabolism and remove these contaminants. The aim of this study was to enrich a microbial community and examine its potential to degrade petroleum hydrocarbon. Through successive enrichment, we obtained a bacterial consortium using crude oil as sole carbon source. The 16 S rRNA gene analysis illustrated the structural characteristics of this community. Metagenomic analysis revealed the specific microbial organisms involved in the degradation of cyclohexane and all the six BTEX components, with a demonstration of the versatile metabolic pathways involved in these reactions. Results showed that our consortium contained the full range of CDSs that could potentially degrade cyclohexane, benzene, toluene, and (o-, m-, p-) xylene completely. Interestingly, a single taxon that possessed all the genes involved in either the activation or the central intermediates degrading pathway was not detected, except for the Novosphingobium which contained all the genes involved in the upper degradation pathway of benzene, indicating the synergistic interactions between different bacterial genera during the hydrocarbon degradation.
