Abstract:
The growth of oyster mushrooms (Pleurotus ostreatus) requires a lignocellulose-containing substrate such as sawdust and baggase. The purpose of this study was to analyze the optimal formulation of a combination of sawdust and bagasse with which inoculated on the growth of oyster mushrooms mycellium the addition of local isolates Aspergillus fumigatus TT and Aspergillus sp II. The experiments were arranged in factorial complete randomized design with factor of substrate and isolate. The results showed mycelium growth was effected by the substrate. The highest growth rate of P. ostreatus mycelium was found in 30% sawdust + 70% bagasse with Aspergillus fumigatus TT (1.24 cm/day), 30% sawdust + 70% bagasse with A. fumigatus TT + Aspergillus sp II (1.38 cm/day) and 100% bagasse with A. fumigatus TT (1.39 cm/day). Combination of bagasse without of isolate in substrat result in a longer of primordium initition
