摘要

采用了低能氮(N,+,)注入技术，对发酵生产番茄红素的三孢布拉霉,Blakeslea trispora, (−) 进行了诱变选育研究。实验结果表明N,+, 注入,B.trispora, (−) 后得到较高的突变率和较广的突变谱，并通过诱变筛选得到BH3-701 等4株高产菌株，经过连续五代遗传稳定性实验考察，高产菌株番茄红素的平均产量比出发菌株提高50%。其中BH3-701表现出很强的发酵积累番茄红素的能力，尤其在发酵后期更为突出，极大地提高了生产效率。

Abstract

In this paper the mutation of lycopene producing strain,B.trispora,(−) by use of low energy N,+, ion implantation,was studied. Experimental results show that higher mutation rate and wider mutation spectrum have been obtained after ,B.trispora, (−) being implanted and four lycopene high yielding strains ,B.trispora, (−) BH3-701 ,et al, have been screened out. It has been found that the average production of lycopene increases by 50% compared with that of original strain after five passages in shaking flasks. The highest yield strain BH3-701 can accumulate lycopene in the later stage and increase production efficiency greatly.
