When the temperature of culture plates was increased from -1+ to .*+, the spore number (/ml) after sporulation treatment was observed to increase, and the number of spores was maximized by using cells from the second culture day. In a previous study, the addition of *.*+ mmol/ l Mn,, to the culture medium increased the spore ratio (ratio of spore number to whole cell number) from 1,ῌ (data obtained in a previous study) to more than 3*ῌ. In the present study, as inorganic Mn,, was not permitted as a food additive, we prepared extracts from four foods with high Mn,, content : dry sea lettuce, raw and dry green laver, and poppy seeds. By adding these extracts to the medium we could achieve a spore ratio of more than 3*ῌ. There were no large di#erences in organoleptic test results for natto produced with starters prepared from four kinds of food extracts.
