摘要：
Various kinds of ethanol-producing marine yeasts from coastal water were isolated and characterized. Number of colony forming units of the marine yeasts on a medium were from several dozen to hundreds per 1 l of various coastal water. Ethanol productivity from glucose by 15 isolates of the marine yeasts widely ranged 9 similar to 77%. Above all, in five strains: TA8, 15, and 46 and TK5 and 12, the productivity was 58 similar to 77% which had the similar levels of those in industrial yeasts. Salt tolerance of the marine yeasts was measured and they grew and fermented in the presence of 2.0 similar to 3.0 M NaCl. Otherwise, the industrial yeasts were only in 1.0 similar to 2.0 M NaCl. In taxonomy of the marine yeasts, most of them were found to be genera Candida and Debaryomyces.
