Related are a recombinant microorganism for producing L-valine, a construction method and an application thereof. Through transferring an amino acid dehydrogenase gene and/or activating activity of a transhydrogenase and/or a NAD kinase, reducing power of NADPH in cell is increased, the titer and yield of L-valine generated by Escherichia coli are improved, and the production of L-valine by one-step anaerobic fermentation is achieved.

Yeast cells having a reductive TCA pathway from pyruvate or phosphoenolpyruvate to succinate, and which include at least one exogenous gene overexpressing an enzyme in that pathway, further contain an exogenous transhydrogenase gene.

The disclosure provides an engineering bacterium for ferulic acid production, a preparation method of the bacterium and use thereof. The invention provides an engineering bacterium that can efficiently produce ferulic compounds by expressing a series of heterologous enzymes in a host cell through gene recombination technology. The expression system constructed by the invention has low metabolic background, strong heterologous expression ability and low cost. The system can synthesize the end product through relatively simple steps, and provide a new way for the industrial production of ferulic acid, intermediates or derivatives thereof.
