The production of L-lysine with the strains Brevibacterium flavum and Corynebacterium glutamicum using sacchapose technology and non-standard nitrogen sources such as hydrolysates of extracted rape, flax and cotton-plan crush and hydrolysates of fodder yeast was studied. Using these N-sources the production in a range from 36 to45 gL-lysine per litre of a cultivation broth in 96-120 h of the culture was achieved. The results show a possibility to substitute peanut meal by inland raw materials. In addition, using these substitutes the quantity of N-source in the culture medium can be optimalized.
