Title: STUDIES ON ECOLOGICAL DISTRIBUTION OF MICROORGANISM ON THE SURFACE OF JUNSAI LEAVES AND ON FACTORS AFFECTING POLYSACCHARIDES FERMENTATION BY MUCILAGE-PRODUCING BACTERIA STRAIN 5242
Abstract:Research work was focused on: Investigating of the environmental conditions for Junsai(Brasenia schrebet) growing; Analyzing the ecological distribution of microflora on the surface of Junsai leaves; ...Research work was focused on: Investigating of the environmental conditions for Junsai(Brasenia schrebet) growing; Analyzing the ecological distribution of microflora on the surface of Junsai leaves; Analyzing the constitutes of Junsai polysaccharides; Investigating the relationship existing between Junsai polysaccharides and polysaccharides-producing bacteria; Identifying the high-yield polysaccharides-producting strain; Studying on the factors affecting polysaccharides fermentation; Testing and measuring some physicochemical properties of polysaccharides produced by bacteria. The results are briefly described as follows: 1. Junsai polysaccharides contain a great deal of polysaccharides-producing bacteria, the distribution of polysaccharides-producing bacteria is related to some degree with Junsai polysaccharides. 2. The composition of Junsai polysaccharides is similar with that of polysaccharides produced by polysaccharides producing bacteria strain 5242. 3. The result of identification denotes that the polysaccharides producing strain 5242 belong to a new species of Acinetobacter, which the authors give the name A. brasenica n. sp. 4. As for polysaccharides fermentation, the polysaccharide product is largely accumulated during the late Logarithm phase and the Steady phase polysaccharides are being produced while the PH value is changing. 5. Strain 5242 has a high capability of producing polysaccharides and its extracellular polysaccharides has potential bioactivity.Read More
