STRAIN OF BREVIBACTERIUM FLAVUM CCM 4263 MICRO-ORGANISM PRODUCING L-LYSINE

摘要

l - lysine, essential amino acid used for fattening livestock (pigs), synthesizes and accumulates in the medium of brevibacterium flavum ccm 4263 mutant bacterial species.resistant to s - (2 - aminoehyl) - of l-cysteine, dependent on the homoserin, leucine, valine, and sensitive to the fluopyruvatu sodnu00e9mu which grown in flasks under aerobic conditions for 4 days at 28.sup.o.n.c in the medium with sucrose, hydrolyzu00e1tem peanut flour and corn with the produced 55 g / l l - lysine at a minimum accumulation of l - valine in the environment (1 g / l).this tribe, verified in laboratory scale fermentation tanks, production reached 92 g / l l - lysine in 68 h at 43%.u0155 conversion
