Acetic acid, lactic acid, valine, aspartic acid, alanine for L - threonine main by-product of fermentation. Including acetic acid, generally two kinds of conditions, equipment engineering bacteria to breathe oxygen deficiency is restricted or glucose consumption rate is greater than the engineering bacteria TCA cycle flow ability. When acetic acid can inhibit the production of L - threonine, no more than 2 g/L. As with lactic acid, valine is mainly due to the lack of dissolved oxygen, when the dissolved oxygen, valine concentration will not increase, the new use of lactic acid bacteria can be weight. And relative to the acetic acid, under the aerobic condition, bacteria lactic acid production of L - threonine impact is not big, but when its concentration is higher than 10 g/L, can inhibit the synthesis of threonine.
