Petroleum hydrocarbons are released into the marine environment from anthropogenic activities like the drilling, manufacturing, storing, and transporting of crude oil and oil products. Due to climate change which opens up new shipping routes in the Arctic, there is an increased risk of oil spills due to oil and gas exploration and increased marine traffic in this area. Oil biodegradation in the marine environment is mediated by microbial consortia operating in cooperative metabolic networks, in which a particular microbial species is capable of degrading a certain crude oil components and the product of one oxidation process fuels another. The response of the microbial community to an oil spill at sea is dependent on oil composition and environmental conditions. There is evidence of oil biodegradation occurring at low and sub-zero temperatures but information about to what extent and which microorganisms are involved/contribute to the biodegradation process in the cold marine environment is still scarce. Due to the abovementioned reasons, there is an increased need for more information on the microbial community capacity to degrade oil compounds at taxonomic, functional and genomic levels in the cold marine environment. Recent advances in molecular and data analysis methods allow using multiple sources of information derived from different omic technologies for providing a better understanding of marine microbial community taxonomic and functional structure and its association with oil exposure and oil biodegradation activity. The obtained information enables better predictions for intrinsic biodegradation capacity of oil fractions in seawater, sediments and coastal material and allows assessing and developing specific mitigation approaches for the prevention of negative impact of oil pollution on important ecosystem functions such as nutrient cycling and hypolimnion hypoxia in the cold marine environment.
This Special Issue will publish papers that address: (1) microbial community and metabolic pathways responsible for the degradation of different oil fractions in different marine compartments of the cold marine environment (2) microbial capacity at the taxonomic, functional and genomic levels to respond to and degrade hydrocarbons resulting from the oil spill in the cold marine environment (3) development and application of bioremediation approaches for marine oil spill response in the cold climate and ice-infested areas

Manuscripts should be submitted online at www.mdpi.com by registering and logging in to this website. Once you are registered, click here to go to the submission form. Manuscripts can be submitted until the deadline. All submissions that pass pre-check are peer-reviewed. Accepted papers will be published continuously in the journal (as soon as accepted) and will be listed together on the special issue website. Research articles, review articles as well as short communications are invited. For planned papers, a title and short abstract (about 100 words) can be sent to the Editorial Office for announcement on this website.
Submitted manuscripts should not have been published previously, nor be under consideration for publication elsewhere (except conference proceedings papers). All manuscripts are thoroughly refereed through a single-blind peer-review process. A guide for authors and other relevant information for submission of manuscripts is available on the Instructions for Authors page. Microorganisms is an international peer-reviewed open access monthly journal published by MDPI.
Please visit the Instructions for Authors page before submitting a manuscript. The Article Processing Charge (APC) for publication in this open access journal is 2700 CHF (Swiss Francs). Submitted papers should be well formatted and use good English. Authors may use MDPI's English editing service prior to publication or during author revisions.
