AI Technical Summary
In existing methods for cultivating methanol-utilizing bacteria, the efficiency of methanol protein synthesis is low, and the methanol metabolic flux is difficult to convert into bacterial protein efficiently and directionally, resulting in significant carbon loss.
A multi-stage culture method was adopted, using glucose and methanol as carbon sources, combined with ammonium salts and nitrates as inorganic nitrogen sources. By adjusting the ratio of carbon and nitrogen sources, and by adding phosphates and trace elements, the metabolic pathway of the bacteria was controlled to achieve efficient methanol synthesis.
It improved the synthesis efficiency of methanol protein, reduced the loss of carbon source, realized the efficient conversion of methanol into bacterial protein, and enhanced the metabolic efficiency of bacteria.
