    摘要:

    為了探討磁場(chǎng)對(duì)工程菌發(fā)酵性能的影響，研究了紫色紅曲霉在50 Hz低頻交變磁場(chǎng)0~2 mT條件下，固態(tài)發(fā)酵生物量的變化規(guī)律。結(jié)果表明，磁場(chǎng)處理3 d對(duì)紅曲霉生物量的產(chǎn)生具有促進(jìn)作用，其中0.6 mT作用最大，提高了29.9%。0~2 mT磁場(chǎng)處理15 d，處理組和對(duì)照組在第11天生物量達(dá)到最大值。處理組和對(duì)照組的生物量與底物消耗量的比值無(wú)明顯差異。低頻交變磁場(chǎng)可促紅曲霉生長(zhǎng)、進(jìn)而可改變其代謝途徑，提高發(fā)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. 
