Abstract:
Objective To study the ability of disintegrating amylum of B.subtilis HY,02 producing ?,amylase. Methods To inoculate B.subtilis to amylaceous solutions with different concentration of 0.5%, 1.0%, 1.75% respectively for consecutive 24 h cultivation, observe the ?,amylase activity, amount of germs and the consumption of amylum at different time. Results The ?,amylase, the amount of germs and the consumption of amylum of B.subtilis(HY,02) obviously increased when the amylaceous concentration was 1.75% compared with those in 0.5% and 1% amylaceous solution groups. Conclusion The present experimental results show that the disintegrating amylum ability of B.subtilis(HY,02) is very strong compared with the old B.subtilis.
