  Author(s): Mervat Morsy Abbas Ahmed El-Gendy* and Nourah Hassan Alzahrani
  
  Glucoamylase production has been evaluated under solid-state fermentation of agro-industrial residues including groundnut shell, corncob, corn stover, sugarcane bagasse, wheat straw, barely straw and rice straw as renewable cheap substrates by different 14 endophytic fungal species. Among them the endophytic fungi Penicillium javanicum obtained from the root of Solanum tuberosum L. showed the maximum yield of glucoamylase using groundnut shell as solid substrate (289.23 ± 0.80 U/gds). Under the optimized production parameters in solid state fermentation process (250 mL Erlenmeyer flask containing 20 grams groundnut shell supplemented with 30% soya waste as an inexpensive, eco-friendly way of enzyme production sieved to 1mm, moistened to 55% initial moisture content with potato process wastewater, pH 5.0, inoculum intense 2 × 108 spore and incubated at 30°C for 5 days ..
