Beschreibung
Zusammenfassung:	FIELD: biotechnology, microbiology, amino acids. ^ SUBSTANCE: invention represents a method for preparing L-threonine by using microorganisms belonging to genus Escherichia and this bacterium is modified for aim of increasing activity of aspartate beta-semialdehyde dehydrogenase. Microorganisms are culture in nutrient medium followed by isolation of prepared and accumulated L-threonine from cultural medium, Invention provides preparing L-threonine with high degree of effectiveness. ^ EFFECT: improved preparing method. ^ 11 cl, 1 tbl, 2 ex
