Characterization of Five Psychrotolerant Alcanivorax spp. Strains Isolated from Antarctica
Five psychrotolerant Alcanivorax spp. strains were isolated from Antarctic coastal waters. Strains were screened for molecular and physiological properties and analyzed regarding their growth capacity. Partial 16S rDNA, alk-B1, and P450 gene sequencing was performed. Biolog EcoPlates and the API 20E...
