title: Polysaccharide produced by Anacystis nidulans: its ecological implication.
abstract: An extracellular polysaccharide from Anacystis nidulans was extracted from cell-free medium. Analysis showed that the polysaccharide consisted of glucose, galactose, and mannose in the ratio of 60:14:20. The production of polysaccharide depends on the age of culture, the growth temperature, and the form of nitrogen available.
