The desert cyanobacterium Anabaena variabilis produces an exopolymer during the stationary growth phase in batch culture. Optimal polymer production was observed at pH 10 under phosphorus limitation. Chemical analysis showed it to be composed of 49% carbohydrate and 19% protein. Monosaccharide analysis revealed a heteropolysaccharidic nature with glucose, mannose, and galactose as the main neutral sugars. Infrared (IR) spectrum of the exopolymer showed absorption bands at 1,645 and 1,421 cm−1… CONTINUE READING
