• The cell-free extract prepared from staphylococci under low temperature in vacuo hydrolyzes thiamine and the action coincides with that of thiaminase II. This enzyme is thermolabile and nondialyzable. The optimum pH is about 7.0 and the optimum temperature is 40°. It is strongly inhibited by copper, mercury and silver ions. It does not break down the disulfide forms of thiamine but degrades many thiamine derivatives. These results suggest that thiaminase II is present in bacteria other than B. aneurinolyticus, though minor in activity.
