摘要:建立了静息细胞培养系统,并以此研究了L-谷氨酸氧化酶生物合成的影响因素。结果表明,发酵16h的菌体在有诱导物情况下有酶的合成,无诱导物则无酶的合成,发酵40h的菌体在有、无诱导物的条件下均有酶的合成。对发酵16h的菌体研究表明:β-丙氨酸(Ⅰ)、α-酮戊二酸(Ⅱ)、丙酮酸钠(Ⅲ)是酶合成的诱导物,谷氨酸(Ⅳ)则不是。而对发酵40h菌体而言:MgCl_2,CaCl_2能促进酶的合成;Ⅰ不能作氮源利用;Ⅰ~Ⅳ均具有高浓度抑制产酶、低浓度促进产酶的双重作用。
Resting cell culture system was set up. The effects of several amino acids,metallic ions and organic acids on biosynthesis of GO were studied in this system. The resultsshow:β-alanine(Ⅰ),α-keto-glularic acid(Ⅱ)and sodium pyruvate(Ⅲ)can induce the youngcell which can not produce GO without inducers to produce GO in resting cell culture system,while glutamate(Ⅳ)can not.Ⅰ~Ⅳ with low concentration have favorable effects,whilethey all with high concentration have advcrse effects on biosynthesis of GO by the grown cellwhich can produce GO in resting cell culture system without inducers.
