Chitinolytic bacteria
WebChitinolytic bacteria were isolated from sediments and chitin flakes immersed in the water of a sand dune lake, Sakata, in Niigata, Japan. Thirty-one isolates from more than 5100 isolated strains were examined chitinase activity and biofilm formation. Phylogenetic analysis of these isolates based on the 16S rRNA gene sequences revealed that ... WebThe previously isolated chitinolytic bacteria showed high antifungal potential against Fusarium oxysporum, and Alternaria spp. The halotolerant bacterial strains were previously isolated showing a salt tolerance of up to 20% in culture media. Specially designed microcosms were used here to investigate the reclamation of saline soil by bacteria.
