为改进微生物发酵法生产谷氨酰胺的流程，提出用电渗析方法来分离谷氨酰胺和谷氨酸。
In order to improve the microorganism fermentation process of producing glutamine, an electrodialysis method was developed to separate glutamic acid and glutamine.
该谷氨酰胺合成酶是自氨基端第405位氨基酸残基突变为苯丙氨酸的谷氨酸棒杆菌的谷氨酰胺合成酶。
The said glutamine synthetase is prepared by abrupt change of the 405th amino acid residue of amino end to phenylalanine corynebacterium glutamicum .
例如，酸处理破坏谷氨酸盐和天冬酰胺酸，而碱处理破坏胱氨酸、丝氨酸和苏氨酸，并产生赖氨酞胺丙氨酸和D -氨基酸。
For example, acidic treatments destroy glutamine and asparagine, whereas alkaline treatments destroy cystine, serine and threonine, and produce lysinoalanine and D-amino acids.
谷氨酰胺-谷氨酸、亮氨酸、组氨酸及牛磺酸浓度的降低反映了小儿恶性实体瘤的氨基酸代谢特点。
The decreased levels of glutamine, leucine, histidine and taurine reflect the nature of the tumor′s metabolism.
为进一步提高从废糖中提取谷氨酸的得率与生产能力，采用AFC99聚酰胺半透膜进行了反渗提取试验研究。
Extracting glutamic acid from waste sugar by AFC99 polyamide membrane with reverse osmosis was tested with increase in extraction percentage and producing efficiency.
用羧甲基化的以N，N’-甲叉双丙烯酰胺交联的烯丙基葡聚糖（简称CM-CADB）凝胶酶载体用树脂为新型载体，将谷氨酸脱羧酶固定在CM-CADB树脂上。
