The effect on the thiaminase production by Clostridium thiaminolyticum (D-9) was tested with the media S-containing substaces. Addition of 10^<-2>M L-cysteine or DL-homocysteine was found to promote the thiaminase production, whereas the disulfide forms of the compounds were found to be inhibitory. Sodium thioglycolate and L-methionine were without effect, but BAL and glutathione were extremely inhibitory. The effects of these SH-compounds on thiaminase activity were found to be somewhat promoting. The effects of thiamine and its derivatives on the thiaminase production were promoting in the media containing cysteine (10^<-2>M) but were inhibitory in the media free from cysteine. Anti-thiamine substances inhibited thiaminase production.
