Abstract

SUMMARY: Certain single-cell strains of brewer’s top fermentation yeasts require -aminobenzoic acid as an essential nutrient. Relatively large quantities of adenine, together with certain amino-acids, of which methionine and histidine were of prime importance, could substitute for the -aminobenzoic acid.

In the presence of adenine, histidine, and suboptimal amounts of methionine, the addition of any one of seven other amino-acids caused a marked stimulation of growth. These amino-acids were leucine, leucine, leucine, valine, valine, tyrosine and phenylalanine.
