Summary

Anacystis nidulans and Anabaena variabilis contain sufficient sulphur reserves to enable them to perform only one round of growth cycle in the non-sulphur growth medium. Sulphate, sulphite, l-methionine and d-methionine, each can act as a suitable sulphur source, but they differ in respect of their growth promoting action; sulphate uptake seems to be a light driven phenomenon and the sulphate metabolizing enzymes are inducible in nature. Methionine appears to act as a repressor of sulphate-metabolizing enzymes.
