“…The ascending shape of the total carbohydrate production curves indicate potential for even greater production capacity. The observed yields were high compared to those observed in other cyanobacterial species (Bishop et al, 1954;Fogg, 1962;Tischer, 1964, 1965;Davis, 1970;Tischer and Davis, 1971;Sanger and Dugan, 1972;Wang and Tischer, 1973;Rottinghaus, 1979). …”

A polymer-producing strain of unicellular cyanobacteria, Synechococcus sp., was isolated from a coastal lagoon in Florida. This strain, designated BG0011, excreted a highly viscous polysaccharide. Maximum observed growth rates for BG0011 were 2.5 div. day -2 . BG0011 also exhibited nitrogen fixation (nitrogenase) activity under aerobic conditions and grew at near maximum rates in medium lacking reduced nitrogen. Growth and carbohydrate production were enhanced by carbon dioxide enrichment. Rheological study of the extracellular polysaccharide revealed a viscosity versus shear rate curve similar in shape to that of xanthan gum. Maximum observed rate of carbohydrate production was 1 g dry weight liter-' month-'.

“…The ability of extracellular organic material to reduce the toxicity of heavy metals was demonstrated by Fogg & Westlake (1955), showing that cultures of Anabaena cylindrica produced polypeptides which complexed cupric, zinc and ferric ions. Wang & Tischer (1973) demonstrated the presence of polypeptides in Anabaena flos-aquae. Murphy et al (1976) showed the occurrence of hydroxamates when blooms of Anabaena flos-aquae were present in the water column.…”

Diazotrophic batch cultures of Cyanospira capsulata producing large amounts of a soluble exopolysaccharide (EPS) were studied over a period of about 30 days under continuous illumination. The thickness of the capsule surrounding the trichomes remained almost the same throughout the growth phases and the EPS was continuously released into the medium at a rate which was roughly constant throughout the culture period. A mean EPS productivity of about 6 g m -2 day-1 was attained. Purified EPS samples exhibited a saccharidic composition consisting of four neutral sugars (glucose, mannose, fucose and arabinose) and galacturonic acid in a molar ratio of 1 : 1 : 1 : 1 : 2, respectively. The EPS was also characterized by the presence of pyruvic residues and by a protein content of about 2%. O-Acetyl groups and sulphate residues were not detected. The massive release of this polysaccharidic material into the liquid medium made the cultures progressively more viscous.
