The mutant strain of Bacillus subtilis IFBG MK-1 produced tryptophan in an amount 13,8-14,0 g/l. Threonine mutant strain Brevibacterium flavum IFBG MB-8 was produced the target amino acid in an amount of 7,8-7,9 g/l. A passport for mutant strains and culture were deposited in the Depositary "Institute of Microbiology and Virology, National Academy of Sciences of Ukraine". Refined modes of cultivating new strains and the process of extracting the essential amino acids threonine and tryptophan from the culture fluid. Experimental rule biotechnology of amino acids - threonine and tryptophan was done. Product Description popup.authors Іващенко Т. Андріяш Г. Бейко Н. Заболотна Г.М. Прийомов С.І. Тігунова О.
