Description
Summary:Schizosaccharomyces pombe Y-658 is deficient for biotin, pantothenic acid, and inositol. The following amounts per ml are sufficient for maximal growth: biotin, 0.001 μg; pantothenic acid, 0.1 μg inositol, 8.0 μg. The inclusion of either thiamine or pyridoxine in the medium resulted in a significant increase in growth over that which occurred in the absence of both. For a maximal growth rate, both were essential. Adenine and uracil had a stimulatory effect on the early growth of the yeast. Although S. pombe Y-658 utilized either (NH 4 ) 2 SO 4 or asparagine as its sole source of nitrogen, its growth was stimulated by glutamic acid, by aspartic acid, and even more, by vitamin-free casein hydrolyzate. A method of overcoming flocculence is described.
