We have investigated the recovery of exopolysaccharides produced by Sinorhizobium meliloti M5N1 CS bacteria from fermentation broths using different membrane filtration processes: cross-flow filtration with a 7 mm i.d. tubular ceramic membrane of 0.5-microm pores under fixed transmembrane pressure or fixed permeate flux and dynamic filtration with a 0.2 microm nylon membrane using a 16-cm rotating disc filter. With the tubular membrane, the polysaccharide mass flux was mainly limited by polymer… CONTINUE READING
