This experiment was carried out to study the chemical changes brought about in artificial media and sterile herbages inoculated with culture of anaerobe (I) isolated from poor Italian ryegrass (Lolium multiflorum LAM) silage and anaerobe (II) from poor Green Bristle Grass (Setaria viridis L. ) silage respectively. The results obtained were as follows: 1. Both anaerobes did not grow in surface culture, produced gas and undesirable odor, formed endospores, and also were gram-positive catalase-negative rods. Therefore, it would be considered that these rods belonged to the genus clostridium. 2. The pH values in microbial broth cultures of both anaerobes were slightly lower than those in media, but pH values in inoculated herbage cultures of both anaerobes were higher than in sterile herbage. 3. While anaerobe (I) produced a large amount of butyric acid in RCM cultures, they produced a fairly amount of acetic and butyric acids in sterile herbage cultures. 4. The microbial MEM cultures of anaerobe (II) contained small amounts of butyric acids, but large amount of butanol appeared in same cultures.
