Abstract

Recently, Bio-fuel has drawn attention as an alternate fuel due to its advantages over fossil fuels. Many researchers have laid stress on the fermentation of biofuels from renewable and sustainable resources. The continuous rise in the cost of petroleum, depleting fossil fuel reserves and increasing environmental pollution have prompted the scientists to explore alternative energy resources. The sustainable methods are therefore required to be used in producing biofuels to handle the problems related to the hike in crude oil prices, global warming, and decreasing fossil fuel reserves. Bio-fuels like butanol can be generated by using different Clostridium species through the ABE (Acetone-Butanol-Ethanol) process. This paper describes challenges of using Clostridium species, including the pretreatment process. Hydrolysis results in the formation of low and side products. In order to produce biobutanol employing different microbiologic species, it would be essential to develop some novel and promising strains that could overcome technological difficulties in terms of effective butanol production at industrial level.

生物丁醇生产中废物转化为财富的绿色途径研究进展
最近,生物燃料因其优于化石燃料的优点而备受关注。从可再生和可持续的资源中发酵生物燃料是许多研究人员关注的重点。石油价格的持续上涨、化石燃料储量的枯竭以及日益严重的环境污染促使科学家们探索替代能源。因此,为了应对原油价格上涨、全球变暖、化石燃料储量减少等问题,生物燃料的生产需要采用可持续的方法。像丁醇这样的生物燃料可以通过使用不同的梭菌种类通过ABE(丙酮-丁醇-乙醇)过程产生。本文介绍了使用梭状芽孢杆菌的挑战,包括预处理过程。水解导致低产物和副产物的形成。为了利用不同的微生物种类生产生物丁醇,必须开发一些新的和有前途的菌株,以克服在工业水平上有效生产丁醇的技术困难。图形抽象
