EFFECT OF L-CYSTEINE ON α-AMYLASE PRODUCTION AND NUCLEIC ACID METABOLISM IN BACILLUS SUBTILIS

[摘要] Using B. subtilis as material the effects of L-cysteine on the production of α-amylase, RNA and DNA synthesis, cell growth, amino acids incorporation into protein and some other metabolisms were investigated. The strongest inhibition was observed in the synthesis of RNA and, to a lesser extent, in DNA synthesis and α-amylase production. The effect was reversed by some factors contained in yeast extract.
