Solid-state fermentation in an earthen vessel: Trichoderma viride spore-based biopesticide production using corn cobs.

The present study reports the production of Trichoderma viride spores in an earthen vessel using corn cobs. Using 4 kg of corn cobs, spore-based biopesticide was produced after 21 d with a maximum spore count of 2.50 × 10 spores/g of substrate and a moisture reduction from 70.
