Abstract
|
|
|
|
A marine bacterial strain that degraded fucoidan from Ecklonia cava was isolated from seawater. The crude fucoidanase of this strain efficiently degraded fucoidan at pH 8 and 50℃. The crude enzyme hydrolyzed 7.1% (w/w) fucoidan within 24 hrs from an 1% (w/v) fucoidan solution and produced oligosaccharides by endo-type hydrolysis as the reaction products. The results of 16S rRNA gene sequence analysis and biochemical tests permitted a tentative identification of strain SB 1493 as a Pseudoalteromonas species.
