In our previous work, bakery wastes, particularly waste cake,
were found to be a good substrate for glucoamylase (GA) production
[17]. In this study, A. awamori obtained from ABM Chemicals
Ltd (Cheshire, England) was used to produce GA with waste cake
collected from local catering as substrate through SSF. The waste
cake was first ground, sieved and then stored in zipped plastic bags
at 20 C for further experiments. Mixed FW used in this study
was collected from a cafeteria at Nanyang Technological
University. The mixed FW homogenized in a blender immediately
after the collection and then stored in zipped plastic bags at 20 C
for further use. The compositions of waste cake and mixed FW are
presented in Table 1.
