Appearance of EPSs produced by S. rolfsii ATCC 201126 at fermenter scale in MOPT culture medium and subsequently downstream processed. EPSi corresponds to scleroglucan precipitated with isopropanol after 1 (A), 2 (B), or 3 (C) re-dissolution/re-precipitation steps. EPSp illustrates the EPS precipitated with PEG.
