title: [Polysaccharides of Ganoderma lucidum: factors affecting their production].
abstract: The conditions of polysaccharide production by the fungus Ganoderma lucidum were optimized. The maximal yield of endopolysaccharides and exopolysaccharides was observed at 25-30 degrees C, initial pH of culture medium 4.0-6.0, and at a C : N ratio of approximately 18 : 1 and 25 : 1, respectively. The greatest yield of mycelium was reached at a more intensive aeration, and the maximal yield of polysaccharides was observed at a less intensive aeration. The optimal ratio between fungus growth and polysaccharide production was observed at 100 rpm and an aeration of 1.0-1.5 1/1 medium min.
