摘要

合成气发酵是生物质转化为乙醇的一种替代途径,它结合了热化学和生化过程的优点。合成气发酵的主要障碍之一是乙醇的低产量,这是由于发酵系统中微生物细胞浓度低,限制了合成气底物的利用。本研究探讨了发酵培养基的改性对微生物细胞生长的促进作用。修改是为了增加培养基中微量营养素/微量金属和宏量营养素的浓度。结果表明,微生物在改性微量金属培养基中产生的最大质量细胞和最大生长速率分别为0.63 g/L和0.0076 h-1,而在改性宏量营养素培养基中产生的最大质量细胞和最大生长速率分别为0.97 g/L和0.0298 h-1。对常量养分培养基进行改性可以提高生物量的产量,而对微量金属进行改性则相反。同时,改良的宏量营养培养基中合成气发酵乙醇的最大浓度低于标准培养基中乙醇的浓度。

Enhance the Growth of Clostridium ljungdahlii Microbial Cells by Modifying the Medium Composition and Trace Metals
Syngas fermentation is an alternative route that combines the advantages of thermochemical and biochemical processes have been proposed for biomass conversion to ethanol. One of the main obstacles to syngas fermentation is the low yield of ethanol, caused by the limited utilization of the syngas substrate due to low microbial cell concentration in the fermentation system. This research examined the modification of fermentation medium to improve microbial cell growth. The modifications were to increase the concentration of micronutrients/trace metals and macronutrients in the medium. The results showed that the maximum mass cell and maximum growth rate produced by microbial growth in the modified trace metal medium were 0.63 g/L and 0.0076 h-1, while in a modified macronutrient medium were 0.97 g/L and 0.0298 h-1. Modification of the macronutrient medium was able to increase the yield of biomass, but the opposite occurred in the modification of the trace metals. Meanwhile, the maximum concentration of ethanol from syngas fermentation in the modified macronutrient medium was lower than the concentration of ethanol in the standard medium.
