Endoglucanase ACC4 which originates in a fungus Acremonium cellulolyticus, has an activity at a moderate level of saccharifying avicel and a moderate endo-type ratio of the carboxymethylcellulose-liquefying activity to the carboxymethylcellulose-saccharifying activity, shows an optimum pH value of 5.6 and an optimum action temperature of 65 DEG C concerning the saccharifying activity with the use of carboxymethyl-cellulose as the substrate, and has a molecular weight of 56,000 when determined by SDS-polyacrylamide gel electrophoresis. This enzyme is useful in feeds, silage, etc. |
