Growth profile and the production of EPSs of Nostoc sp. FB71 cultivated in media culture without additional sugars as a control a and media culture containing (10 g/l) maltose b, lactose c, sucrose d and glucose e. Symbols indicate (●) for cell dry weight (g/l), (□) for total EPS concentration (μg/ml) and (∆) for sugar concentration (g/l) in the media. Results are the mean of duplicated measurement
