Abstract
|
|
|
|
The marine bacterium isolated from Porphyra dentata showing green spot rot disease was identified as Pseudomonas sp. the strain have CNCase activity, xylanase activity and protease activity as well as agarase activity. But the strain has no pectate lyase activity. Porphyra dentata tissue inoculated this isolate was macerated after 1 week incubation. The characteristics of extracellular crude agarase of this isolate were examined, the optimal pH and temperature were pH7 and 3$0^{\circ}C$, respectively.
