1 氨基酸市场由谷氨酸棒杆菌 Cglutamicum 生产的最大宗氨基酸仍是 L-谷氨酸。其次是 L-赖氨酸和 DL-甲硫氨酸。氨基酸的价格随产量的上升而下降,价格下跌导致需求量的增加,竞争也加剧,然后是更进一步的降低价格。最近十年,氨基酸市场产量翻了一番,有的氨基酸增加得更快。例如,过去20年里,L-赖氨酸增加了20倍以上,据估计其市场每年增加10%～15%,因而造成生产氨基酸公司的资本流动和扩大。对 L-赖氨酸需求的增加是由于这一基本氨基酸用于配制家禽和猪的繁育所需的饲料添加剂的增加造成的,而这一动物饲料使用量的增加恰恰反映了日益增长的肉
1 Amino Acid Market The largest amino acid produced by Cglutamicum is still L-glutamic acid. Followed by L-lysine and DL-methionine. The price of amino acids declines with the rise of output, the price drop leads to the increase of demand, the competition is aggravated, and then the price is further reduced. In the last ten years, the amino acid market has doubled its production and some amino acids have increased more rapidly. For example, L-lysine has increased more than 20-fold over the past two decades and its market is estimated to increase by 10-15% annually, resulting in a capital-inflow and expansion of the production of amino acid companies. The increase in L-lysine demand is due to the increase in feed additives needed to formulate poultry and pigs for this essential amino acid, and the increased use of this animal feed precisely reflects the growing volume of meat
