Fig. 2From: Mutagenesis and characterization of a Bacillus amyloliquefaciens strain for Cinnamomum camphora seed kernel oil extraction by aqueous enzymatic methodThe relationship between fermentation time and exoenzyme activity in a and b. The proteinase, glucoamylase and pectase are shown in a. Cellulase and amylase are shown in b. The activities of enzymes were sampled every 2 h when the cultivation time was between 38 and 48 h. Data are mean ± SD (n = 3). The types and optimum fermentation times of the extracellular enzymes were determinedBack to article page
