| Summary: | Three experiments were conducted to study the cellulase activity of stomach homogenates of green abalone, with and without antibiotics added. Forty-eight previously frozen stomachs from wild abalone adults were thawed and individually homogenized. Four cultured abalone adults maintained under a balanced diet containing cellulose were killed and the fresh stomach samples processed. Cellulase activity was estimated through the production of glucose, incubating the homogenate from each organism with cellulose. To determine the effect of bacteria, each stomach was incubated (at 25 degreesC for 20 h) in a completely randomized design, with and without an antibiotic mixture. For a time series measurement (exp. 2), four homogenates from wild abalone were used |
