Solid-state fermentation for production of griseofulvin on rice bran using Penicillium griseofulvum.
Griseofulvin is a secondary metabolite produced from fungal species that have morphology suitable for solid-state fermentation (SSF). Reports on production of griseofulvin by SSF are scarce. The present work investigates SSF for griseofulvin production, optimization of its process parameters vis-à-vis the conventional submerged fermentation and its downstream processing from the same. Rice bran adjusted to an initial moisture content (IMC) of 50% (v/w) inoculated with 1 mL of a suspension of 10(6) spores/mL under agitation at 250 rpm containing the modified Czapek-Dox medium and additional 0.1% choline chloride as a precursor gave a yield of griseofulvin in 9 days that was comparable to submerged fermentation after 28 days. The yield of griseofulvin (microg/g dry biomass) was comparable in SSF and submerged fermentation. The biomass was estimated by estimation of chitin. Discussions on the effect of each parameter in SSF have also been included.
