FIELD: biotechnology, amino acids.
SUBSTANCE: invention relates to a method for preparing L-amino acids by culturing bacterium of genus Bacillus that shows ability for producing L-amino acids in medium containing methanol as a carbon source followed by collection of L-amino acid from medium or cells of bacterium said. As a bacterium method involves using bacterium comprising the inserted gene encoding enzyme methanol dehydrogenase and enhancing activity of enzymes hexulosophosphate synthase and phosphohexulosoisomerase. Invention provides L-amino acids with the high effectiveness degree.
EFFECT: improved preparing method.
