摘要

Abstract High specific activity L-35 S-cysteine and L-35 S-methionine were synthesised by using a wild type diploid strain of baker's yeast—Saccharomyces cerevisiae. Yeast cells were grown in a sulphur depleted synthetic medium in which Na 2 35 SO 4 (50 mCi/ml) was supplemented as the sole sulphur source. The level of incorporation was 60% on an average. The protein hydrolysate of the cultured cells was subjected to paper and column ...
