摘要：
Agar, agarose and alginate immobilized cells of thermophilic Bacillus sp. WN11 produced 7.0, 6.2, and 10.5 U/ml of thermostable amylase in shake flasks, respectively. Alginate entrapped cells released high level of amylase (10.5 U/ml) than freely suspended cells (8.0 U/ml). Amylase production was stable in five successive batches with productivity of 9-12 U/ml for alginate, 5.5-8.8 U/ml for agar, and 4.8-8.0 for agarose immobilized cells.
