RABELO FLOREZ, Roger Alberto  and  MARQUEZ GOMEZ, Marco Antonio. Gram-negative hydrocarbon-biodegrading bacteria. rev. cienc. [online]. 2020, vol.24, n.2, e9935.  Epub Apr 22, 2022. ISSN 0121-1935.  https://doi.org/10.25100/rc.v24i2.9935.

The objective of this article is to review the most relevant Gram-negative bacteria capable of biodegrading hydrocarbon, and to review the biodegradation techniques used. This review was developed in two stages. The first is a scientific mapping of the subject, through databases like Scopus, Redalyc, Scielo, Dialnet, Latindex, Nature Microbiology, among others, and in the Google Academic. The second stage is an analysis to identifying the most relevant documents. In this process, it was found that the most representative Gram-negative bacterial genera in hydrocarbon biodegradation are Alcanivorax spp., Bacteriovorax spp., Burkholderia spp., Chromobacterium spp., Citrobacter spp., among others. These bacteria can biodegrade hydrocarbons through biosurfactants synthesis by in situ and ex situ techniques. This review is important because it provides sufficient information on the bacteria that biodegrade oil and its derivatives, lists the main biosurfactants used and describes the biodegradation techniques.

Keywords : Bacteria; Biodegradation; Hydrocarbon; Biosurfactant.
