Abstract
The present invention relates to application of a novel signal peptide in L-glutamate and its derivatives production from konjac powder, which belongs to the field of gene engineering, enzyme engineering and metabolism engineering. The signal peptide which mediated secretion of β-mannanase was invented, and the recombinant strain with this signal peptide had advantages on utilizing konjac powder to produce related products, and its utilization efficiency of konjac powder, production efficiency, and yield were higher than other signal peptides. The recombinant strain possessing this new signal peptide had advantages on utilizing cheaper konjac powder as substrate to lower the process costs on L-glutamic acid and its high-value-added products.
