Abstract: The present disclosure relates to a method for preparing a bonito extract by extracting katsuobushi under low temperature and reduced pressure; a bonito extract which is prepared by extraction under low temperature and reduced pressure, and has reduced off-flavor and bitter taste and increased flavor and umami taste; a method for preparing a tuna fish sauce, comprising a processing step of mixing and sterilizing the bonito extract and seasoning ingredients; and a tuna fish sauce.
Abstract: The application relates to a microorganism having weakened activity of a LacI family DNA-binding transcriptional regulator protein, and an L-glutamic acid production method using same. A Corynebacterium sp. microorganism having weakened activity of a LacI family DNA-binding transcriptional regulator protein has remarkably increased L-glutamic acid productivity, and thus the microorganism can produce L-glutamic acid in a yield higher than that of a conventional microorganism by using same.
