Enhancement of Cyclodextrin Glucanotransferase Production by Bacillus G1 using Different Fermentation Modes

H.M. Ibrahim, W.M.W. Yusoff, A.A. Hamid and O. Omar    

Abstract: The objective of this study was to enhance the production of Cyclodextrin glucanotransferase (CGTase) produced by a local isolate Bacillus G1. CGTase produced in an optimized medium using different fermentation modes was investigated. The performance of batch mode, continuous mode and fed-batch mode was achieved in 5 L-stirred tank fermenter. Maximum CGTase production (77.49 U mL-1) was achieved in fed-batch fermentation with 23.7% improvement compared to batch fermentation (62.63) and 16.6% improvement compared to continuous fermentation (66.47). CGTase productivity in fed-batch fermentation (1.6 U/mL/h) improved by 14.3% compared to that obtained by continuous fermentation (1.4 U/mL/h) and 23.1% improvement compared to batch fermentation (1.3 U/mL/h).
