  L-Glutaminases have received significant attention recently owing to their potential applications. All endophytic fungi recovered from the marine soft sponge Aplysina fistularis were able to produce L-glutaminase. During screening program, Aspergillus sp. ALAA-2000 showed the highest L-glutaminase production levels. The production of L-glutaminase by Aspergillus sp. ALAA-2000 was evaluated under different fermentation modes and parameters. The L-glutaminase synthesis was increased their yield after the optimization of fermentation parameters. The hot water 40°C was the best leaching agent extracted of soy bean for L-glutaminase production (21.89 U/ml) under solid state fermentation (SSF). The highest L-glutaminase activity (91.92 U/ml) was achieved after two days incubation period under submerged fermentation (SmF). L-glutamine, dextrose, cysteine and Magnesium chloride supported ..
