Potato starch and its hydrolizates were used to substitute glucose cabon souces to synthesize glucose oxidase (GOD) by free and immobiized on pumice stones A.niger mycellium.The basic conditions for starch hydrolisis, securing the maximal enzyme yields, were optimized.The immobilized A.niger mycelium was able to produce the enzyme at a small loss of its acting (about 28%) during ten 24-h batches.Free mycelium produced about 1.5 times higher GOD activity than the immobilized mycelium on glucose and starch hydrolizates.However,the latter was more stable, reaching faster the maximum of enzyme productivity, and it could be used many times with almost the same efficiency.Thus,the total enzyme yields produced by immunobilized mycelium were much higher than those obtained using the free one.
