KANAZAWA, Japan, April 27, 2021 /PRNewswire/ In a study published in
Applied Microbiology and Biotechnology biologists at Kanazawa University report an increase in the synthesis of fermentation products in bacteria at high reaction temperatures.
Mankind has long relied on fermentation the metabolic processes within microorganisms to procure useful compounds such as lactic acid (found in yogurt and kimchi) and ethanol (present in that daily glass of wine).
Corynebacterium glutamicum is a bacterium used for industrial scale production of lactic acid and succinic acid, which can be used as bio-based plastic monomers. To-date, fermentation in
C. glutamicum is conducted at temperatures of ~30°C, wherein the bacterium can grow comfortably. Now, Hikaru Mizuno and Yota Tsuge from Kanazawa University show that the production efficiency of some fermentation products can instead be magnified by simply increasing the reaction temperature above growth thresholds.
