Figure 4From: Production and downstream processing of (1→3)-β-D-glucan from mutant strain of Agrobacterium sp. ATCC 31750Production of curdlan by mutant M5 strains in a stirred bioreactor with agitation speed 700 rpm and aeration rate 1 vvm, at constant pH after nitrogen limitation compared with wild strain under pH shift condition. Time course profiles are: a) sucrose, b) curdlan production, c) DCW, d) ammonium, e) phosphate and f) pH.Back to article page
