Growth and production by C. carboxidivorans P7 using various temperature strategies. Mean values and standard errors of three replicates are shown in all graphs. a Optical densities at 600 nm (OD600s) in the culture of 25 °C, 29 °C, 33 °C and 37 °C, respectively, during 0–120 h; the approximate time when bacterial agglomerates appeared (BA time) in the culture of 33 °C and 37 °C. c OD600s in the culture of 37–25 °C, 37–29 °C, 37–33 °C and 37 °C, respectively, during 0–120 h; the BA time in the culture of 37 °C and 37–33 °C. b, d Titers of ethanol, butanol, hexanol, acetate, butyrate and caproate at 120 h, using various temperature strategies
