Microbiological performance of Garanver solid fermentation with Trichoderma viride and Aspergillus niger W2

The microbiological performance of Trichoderma ma viride and Aspergillus ni ger W2 was analysed during the solid state fermentation of Garanver. A comp letely randomized design with a 2 x 2 factorial arrangement was used in whi ch the variation sources were two conidial fungi strains and two substrate variants (sterile and non-sterile). The predominance of yeasts and bacteria was confirmed with more than 70% CFU in the first 24 hr of fermentation Af ter 72 hr, conidial fungi pervailed with 89% CFU. The initial microbiote of Garanver hindered Trichoderma viride and Aspergillus niger W2 growth.
