Complete genome of brown algal polysaccharides-degrading Pseudoalteromonas issachenkonii KCTC 12958T (= KMM 3549T)

Abstract

Pseudoalteromonas issachenkonii is a Gram-negative, rod-shaped, flagellated, aerobic, chemoorganotrophic marine bacterium that was isolated from the thallus of Fucus evanescens (marine brown macroalgae) sampled from the Kraternaya Bight of the Kurile Islands in the Pacific Ocean. Here, we report the complete genome of P. issachenkonii KCTC 12958T (= KMM 3549T=LMG 19697T=CIP 106858T), which consists of 4,131,541bp (G+C content of 40.3%) with two chromosomes, 3,538 protein-coding genes, 102 tRNAs and 8 rRNA operons. Several genes related to glycoside hydrolases, proteases, and bacteriolytic- and hemolytic activities were detected in the genome that help explain how the strain mediates degradation of algal cell wall and decomposes algal polysaccharides into industrially applicable products.
