Summary: This study investigated the relationship between wild type and engineered strains of the same microorganism in terms of kinetic parameters, and proposed a set of correction factors to estimate kinetic constant values for species or strains for which they are not available. The results showed a correlation between wild type and engineered strains, with specific substrate limitation constants being higher in the engineered strains. These correction factors were found to be conserved and could serve as a guide for estimating kinetic constants in other species or strains.

Summary: This study investigates the role of ZMO0293 in Z. mobilis using gene deletion and heterologous expression methods. The results show that deletion of ZMO0293 gene leads to slowed growth, reduced ethanol production, and decreased activities of key enzymes involved in glucose metabolism in the presence of high concentrations of glucose. Furthermore, ZMO0293 deletion causes transcriptional changes in some genes of the Entner Doudoroff pathway in the ZM4-Delta ZM0293 strain. This study reveals the function of ZMO0293 gene and provides a new biological part for synthetic biology.

Summary: An evolved Zymomonas mobilis strain, F74, with improved molasses utilization was generated through adaptation in fructose, which is mainly attributed to a G99S mutation in Glf for enhanced fructose import. SacB deletion and sacC overexpression in F74 further enhanced the ethanol productivity by diverting sucrose metabolism from levan production to ethanol production. This strategy of adapting and engineering microbial strains for efficient molasses utilization provides a reference for developing microbial cell factories.

Summary: This study investigated the effects of using Zymomonas mobilis and Saccharomyces cerevisiae for simultaneous saccharification and fermentation of sorghum grain, and replacing half the water with a stillage liquid fraction on ethanol yield and volatile compound synthesis. The results showed that Z. mobilis is more efficient in ethanol production with a shorter fermentation time and lower fermentation temperature. Reusing the liquid fraction of the stillage did not increase the amount of volatile compounds, and there were significant differences in the volatile compounds profile of bacterial and yeast raw distillates.
