Fig. 3From: Phasin PhaP1 is involved in polyhydroxybutyrate granules morphology and in controlling early biopolymer accumulation in Azospirillum brasilense Sp7Growth kinetic behavior of A. brasilense strains. A. brasilense strains were inoculated in flasks containing minimal medium supplemented with malic acid and ammonium chloride, at C:N ratios of 30:1, 60:1 and 90:1, to an OD600 of 0.01. Samples were taken every 3 h for 24 h and measured spectrophotometrically at an OD600. Growth of A. brasilense Sp7 (WT) (circles), A. brasilense ΔphaP1 (ΔphaP1) (squares) and A. brasilense PhaP1+++ (PhaP1+++) (diamonds). Dark spots indicate a C:N ratio of 30:1, gray spots for a C:N ratio of 60:1 and light gray spots denotes a C:N ratio of 90:1Back to article page
