The fermentative production of L-lysine as an animal feed additive

A new and innovative process for the biotechnological production of L-lysin e is presented, exemplified here by the fermentative production of the feed additive Biolys (R) 60. The novel feature of this product is that the enti re manufacturing concept, i.e. the production strain, the raw materials, al l process stages and the product specifications have been systematically ta ilored for optimal environmental compatibility and for minimum resource dep letion and waste. The process completely dispenses with the need to dischar ge residual and waste material and reduces the handling of hazardous materi als to a minimum. Since only a few process stages are involved, the method is economical to use and investment outlay is reduced. The process, which a lso leads to a higher grade product, is thus highly attractive in both ecol ogical and economical! terms. By boosting the nutrient value of the plant-b ased feedstuffs, the product itself makes an cost-effective contribution to wards a more sustainable form of animal feeding and by reducing nitrogen em ission levels promotes a more environmentally compatible form of animal hus bandry.
