Statistical optimization for tannase production by Aspergillus tubingensis in solid-state fermentation using tea stalks
Background A sequential statistical strategy was used to optimize tannase production from Aspergillus tubingensis using tea stalks by solid-state fermentation. Results First, using a Plackett-Burman design, inoculum size and incubation time (among seven tested variables) were identified as the most...
