摘要：

An exopolymer producing bacterium Bacillus megaterium was isolated from the infected plant leaf of Aralia species. The isolated organism produced 10-11 g/1 of polymer in a synthetic medium consisting of glucose, ammonium nitrate and various salts. Optimum conditions for polymer production were determined. Amongst various carbon and nitrogen sources tested sucrose and ammonium nitrate gave maximum production. C/N ratio of the medium, temperature and pH for optimum polymer production were also investigated. Some of the physico-chemical properties, such as relative viscosity, specific viscosity and reduced viscosity of the polymer were studied at various concentrations and temperatures. Intrinsic viscosity of the polymer was also determined. (C) 1998 Published by Elsevier Science Ltd. All rights reserved.
