Abstract
In order to assess the stability of molecular and rheological properties of the exopolysaccharide (EPS) produced byCyanospira capsulata the strain was cultivated under both continuous light and light-dark cycles in two culture devices, an open pond and a completely stirred reactor (CSR), having quite different surface-to-volume ratios and stirring systems. All EPS samples obtained from the cultures showed the same monosaccharidic composition and relative proportions among sugar units. However, Gel Permeation Chromatography demonstrated that EPS samples produced by cultures run in open ponds were more homogeneous in size than those obtained from cultures grown in CSR. In spite of this difference, no significant change in the flow properties was observed among the aqueous solutions of the different EPS samples.
