Fig. 2From: The nutritional composition and cell size of microbial biomass for food applications are defined by the growth conditions(a) Correlogram for the relationship between growth rate (h− 1), cell size (diameter, in µm) and macromolecular cell composition (nucleic acid (A.U.), protein (g protein/g CDW), carbohydrate (g carbohydrate/g CDW), PHA and lipid (A.U.) content) in function of substrate (carbon (g COD/L) and nitrogen (g NH4+/L)) concentration for C. necator and K. phaffii. Macromolecular composition and cell size in function of (b) growth rate and (c) cell size throughout the growth of C. necator and K. phaffii. The shaded area indicates the 95% confidence interval of a linear model fit. *The cell size and carbohydrate content of K. phaffii were divided by 5 to allow for better representation of the trends from both organisms in the same graphBack to article page
