Fig. 5From: Use of agro-industrial residue from the canned pineapple industry for polyhydroxybutyrate production by Cupriavidus necator strain A-04Time course of cell dry weight (g/L), residual biomass (g/L), PHB substrate (g/L), produced PHB (g/L), and PHB content [% (w/w)] during bacterial growth on a pineapple peel hydrolysate with a C/N of 200 in production medium, b pineapple core hydrolysate with a C/N of 200 in production medium, c crude aqueous extract with a C/N of 200 in production medium, and d crude aqueous extract without supplementary nitrogen or production medium. The carbon source concentration was 20 g/L in all cases. The error bars represent the standard deviations (n = 3)Back to article page
