利用光合菌发酵对玉米秸杆进行转化的研究*

系统研究了光合菌在氨法处理和非氨处理两种环境下，在厌氧、好氧、以及自然条件下对玉米秸秆的转化。通过发酵液中还原糖与蛋白质浓度的测定结果的比较、判断、优选出一种最适合条件下光合菌对玉米转化的途径。研究表明，在以氨化法处理的玉米秸秆为底物与光合菌的发酵实验中，发酵液中的还原糖和蛋白质的尝试都要比非氨法条件下玉米秸秆为底物与光合菌发酵实验中的发酵液中的不原糖和蛋白质的浓度高。实验结果证明了转化产生的还原糖、蛋白质都是光合菌能利用的营养成分，由此达到利用光合菌转化玉米秸秆的研究目的。

STUDIFS ON TEH UTILIZING THE PHOTOSYNTHETIC BACTERIUM FERMENTATION FOR BIOTRANSFORMATION ON .CORN STRAW

The physiological character,functions and applications of photosynthetic bacterium had been discussed,during biotransformation of teh com straw treated with ammonia in aerobic,anaerobic and natural conditions,Comparing the concentration of teh reductive sugar and teh protein in teh fermented borth,we suggest a good way of biotransformating teh corm straw by photosyntehtic bacterium.In the photosynthetic bacterium fermentation in which the com straw treated substrate,teh concentrations of the reductive sugar and the transformative reductive sugar and teh protein in teh fermented borth were higher thean those without ammonia. Analysis of the results shows theat the transformative reductive sugar and protein were the nourishment of photosynthetic bacterium,so theere may be a way that we harness the corn straw by teh photosynthetic bacterium.
