The feasibility of using pumpkin oil cake (PuOC). individual and in combination with wheat bran (WB). as substrate for the production of Exo-polygalacturonase (Exo-p) by starter culture Penicillium roqueforti in solid state fermentation (SSF) has been evaluated. The kinetics of enzyme production was investigated using PuOC alone in the range from 13 to 168 h. https://danddcollectiblers.shop/product-category/remote-control/
