Abstract
Statistical experimental design was used to optimize the physical conditions such as temperature and speed of agitation in shake flask culture to enhance cyclodextrin glucanotransferase (CGTase) production from Bacillus sp. G1. Response surface methodology with appropriate statistical experimental design was employed for this purpose. The maximal level of extracellular CGTase was achieved (41.4 U/ml) when the speed of agitation and temperature were 147.7 rpm, 34.48°C respectively.
