A. Pandey et al., GLUCOAMYLASE PRODUCTION BY ASPERGILLUS-NIGER ON RICE BRAN IS IMPROVEDBY ADDING NITROGEN-SOURCES, World journal of microbiology & biotechnology, 10(3), 1994, pp. 348-349
Corn steep liquor, peptone or NH4+ salts increased the yield of glucoa
mylase from Aspergillus niger growing in a solid-state fermentation on
rice bran up to 360 IU/g dry substrate over 96 h at 30-degrees-C.
