Cell proliferation is achieved through numerous enzyme reactions. Temperature governs the activity of each enzyme, ultimately determining the optimal growth temperature. The synthesis of useful chemicals and fuels utilizes a fraction of available metabolic pathways, primarily central metabolic pathways including glycolysis and the tricarboxylic acid cycle. However, it remains unclear whether the optimal temperature for these pathways is correlated with that for cell proliferation. Here, we found that wild-typeCorynebacterium glutamicumdisplayed increased glycolytic activity under non-growing anaerobic conditions at 42.5 degrees C, at which cells do not proliferate under aerobic conditions. At this temperature, glucose consumption was not inhibited and increased by 28% compared with that at the optimal growth temperature of 30 degrees C. Transcriptional analysis revealed that a gene encoding glucose transporter (iolT2) was upregulated by 12.3-fold compared with that at 30 degrees C, with concomitant upregulation of NCgl2954 encoding the iolT2-regulating transcription factor. Deletion of iolT2 decreased glucose consumption rate at 42.5 degrees C by 28%. Complementation of iolT2 restored glucose consumption rate, highlighting the involvement of iolT2 in the accelerating glucose consumption at an elevated temperature. This study shows that the optimal temperature for glucose metabolism inC. glutamicumunder anaerobic conditions differs greatly from that for cell growth under aerobic conditions, being beyond the upper limit of the growth temperature. This is beneficial for fuel and chemical production not only in terms of increasing productivity but also for saving cooling costs.
