Exploring the Potential and Evaluating Hydrocarbon Degradation by Novel Antarctic Dietzia and Pusillimonas Isolates From a Pristine Environment.

ABSTRACT: This study evaluated the bioremediation potential of two psychrotolerant strains, Pusillimonas sp. ANT_WB101 and Dietzia sp. ANT_WB102, isolated from an uncontaminated water pond. Comparative analysis indicated affinities with P. gingsengisoli/soli and D. kunjamensis/maris. Both strains demonstrated substantial crude oil degradation efficiency, achieving ≥ 79% under aerobic conditions and ≥ 34% under anaerobic conditions. Genomic analysis identified crucial genes involved in crude oil degradation, including alkane monooxygenase, cytochrome P450, and polyphenol monooxygenase. These strains displayed adaptability to a wide range of environmental factors, such as pH (4-11), salinity (up to 6%-9%), temperature (4°C-37°C), resistance to freeze-thaw cycles, and tolerance to high crude oil concen
