glutamine

The feeding of glutamic acid , glutamine and a - keto - glutaric acid respectively showed that glutamic acid and glutamine had no obvious effects on cell growth , but stimulated apramycin production greatly . with the same concentration of amino acids supplemented , glutamine showed a stronger stimulation effect than glutamic acid , while a - keto - glutaric acid showed a repression effect on apramycin production . it could be deduced from above results that glutamine possibly is the donor of nitrogen element for the biosynthesis of apramycin Glu 、 gln及?酮戊二酸添加實驗結果表明glu 、 gln對菌體的生長無明顯的影響,但能強烈促進安普霉素的生物合成,且相同濃度條件下gln的促進作用明顯高于glu ,而?酮戊二酸則對安普霉素的生物合成有抑制作用。

Arginine feeding experiment showed that nitrogen metabolism in the s . tenebraius was obviously affected by arginine through two possible ways : ( l ) pronase activity in vitro could be influnced by arginine , as a result , the catabolism of nitrogen - containing macro - molecule was promoted and the nitrogen element in the broth was increased . ( 2 ) arginine could be transformed into glutamic acid , so that the biosynthesis of apramycin was promoted 因而我們認為gln可能是安普霉素生物合成氮元素的供體。 arg添加實驗結果表明, arg可能通過兩種途徑影響黑暗鏈霉菌體內的氮代謝: ( 1 ) arg可能影響胞外蛋白酶的活性,進而促進含氮大分子物質的分解代謝,補充發酵過程中的氮素來源。
