Abstract
On the gastrointestinal bacteria related to nutrition, there have been many importantpublications. Recently, the present author has attempted further researches on Aerobactermannanolyticus suzu-II, a strain in the type cultures collected by N. Inoue in this laboratoryfrom human gastrointestinal tract, and the enzyme specificity was studied. The isolation ofthe “Konjac” mannan decomposing enzyme preparation was completely successful, and effectsof carbon and nitrogen sources in Koser's citrate medium on the enzyme formation were also confirmed. In the present paper, the results are described.
