Twenty six Chinese starters, “Murcha”, were collected from 25 different parts of Kingdoma ofNepal from December, 1993 to January, 1994.Their yeasts and molds were isolated and identified. Yeasts were pmesent in 24 kinds of “Murcha” in the range of 1.0×10⁷-1.6×10⁹ colony forming units per (CFU) per gram whereas molds were in 26 kiuds of “Murcha” in the range of 3.0×10³-4.2×10⁶ CFU per gram.Isolates belonging to genus Saccharomycopsis were found in 22 out of 24 kinds of “Murcha” and consituted more than 50% of the yeast distribution ratio in 18 kinds of “Murcha”.The one group of the isolates was identified as Saccharomycopsis fibuligera that distributed 11% to 100% of the yeast distribution ratio in 21 kinds of “Murcha”, especially 100% in 10 kinds.Saccharomycopsis fibuligera was confirmed to be the most dominant yeast in “Murcha” from Nepal.Theresult was the same as finding for Chinese starters from other Asian countries. The other group of the genus isolated from 4 kinds of “Murcha” hydrolyzed starch as vigorously as S. fibuligera but differed in assimilation of galactose and growth on vitamin-free medium.Saccharomyces cerevisiae was isolated in only 5 kinds of “Murcha”. “Murcha” from which S. cerevisiae was not isolated, had been left on shelves before our purchase and was not fresh.On the other hand, mold isolates belonging to genera Rhizopus, Absidia, and Mucor were found to be dominant, but none of them showed high saccharifying ability.Therefore, Saccharomycopsis fibuligera is likely to play a major role in saccharification of Chinese starter “Murcha” from Nepal like the ones from other countries.

バウムクーヘン,カステラおよびカルカンに生育する糸状菌の種類と数について検討し,分離菌について生育最適温度および胞子の発芽時間の測定を行なった。
カルカンは水分含量が比較的高く,Wallemia,Cladosporium, Penicilliumなどが主要な生育菌であった。カステラでは,Penicillium, Cladosporiumが減少し,Wallemia, Aspergillusが主要菌となり,水分含量の更に低いバウムクーヘンでは,好浸透圧性のAspergillusが主要菌となった。
炭酸ガスは,空気と同程度の酸素の存在下でも,糸状菌に対してかなりの静菌効果を示し,特にその効果はWallemia Cladosporiumに対して著しかった。
