| 摘 要： | 为了探讨磁场对工程菌发酵性能的影响,研究了紫色红曲霉在50 Hz低频交变磁场0～2 mT条件下,固态发酵生物量的变化规律。结果表明,磁场处理3 d对红曲霉生物量的产生具有促进作用,其中0.6 mT作用最大,提高了29.9%。0～2 mT磁场处理15 d,处理组和对照组在第11天生物量达到最大值。处理组和对照组的生物量与底物消耗量的比值无明显差异。低频交变磁场可促红曲霉生长、进而可改变其代谢途径,提高发酵效益。

| Abstract: | The biomass of Monascus purpurcus solid-state fermentation influenced by low frequency alternating magnetic field(50 Hz,0~2 mT) was main studied in order to discuss the magnetic field influence on the performance of engineering bacteria fermentation.Results showed that the magnetic treatment could promote Monascus purpurcus biomass producing in the third day with the maximum improving of 29.9% at 0.6 mT.The biomasses of treatment group and control group reach maximum in the eleventh day with the whole procedure of 15 days and magnetic field intensity of 0~2 mT.But the biomass and substrate consumption ratio of treatment group and control group did not show obviously difference.Low-frequency alternating magnetic field could promote Monascus purpurcus growth,then change their metabolic way and enhance the fermentation benefits. |
