| 摘 要： | 萘降解菌LHJ38在金属盐培养基中加入水杨酸钠诱导培养后能提高其生物合成靛蓝的能力,在LB培养基中加入水杨酸钠反而抑制了其生物合成靛蓝的能力.与LHJ38最适生长pH值不同,LHJ38生物合成靛蓝的最佳pH值范围是8.45—9.45,在pH为8.95的情况下生物合成靛蓝能力是其在pH值为6.95的情况下的两倍.

| Abstract: | The biosynthesis of indigo by naphthalene-degrading bacteria LHJ38 from indole has been studied.Indigo formation capacity by LHJ38 growing in mineral salts medium in the presence of salicylate greatly increased,contrarily,indigo formation capacity by LHJ38 growing in LB medium in the presence of salicylate decreased by 2 times.The optimum pH ranges for biosynthesis of indigo is 8.45~9.45 which is different from the incubation pH of LHJ38,and indigo formation by LHJ38 growing in LB medium at pH 8.95 increased 2 times compared with that at pH 6.95. |
