Studies on Fermentation of Soysauce Mash

Part III. Effect of ether extract of soysauce on Sacch. rouxii

Abstract

Ether extract of soysauce had two remarkable effects on the growth and fermentation of Sacch. rouxii. One was an inhibitory effect on the growth and the other was an enhancing effect on the fermentation ability of the yeast. Three partitioes (acid partition, weak acid partition and neutral partition) from the ether extract were investigated on their effect on the yeast resulting in the finding only the weak acid partition had the two effects and it was recgnized that weak acid partition were effective.
