| Research Abstract |
For the effective use of marine biomass resource seaweed, we searched for extremophiles such as halophiles and alkaliphiles from various sea organisms. We found new carbohydrate-degrading enzymes from the extremophiles. In addition, alkaliphilic lactic acid bacteria degraded hemicellulose, xylan to produce lactic acid, acetic acid, and ethanol effectively. The extremophiles showed slightly lactic acid fermentation from seaweed, too. These results suggest that extremphiles are new microbial resource and are also resource of new carbohydrate degrading enzymes.
