An integrated approach: advances in the use ofClostridiumfor biofuel

Abstract

Almost 90% of our energy comes from fossil fuels, which are both limited and polluting, hence the need to find alternative sources. Biofuels can provide a sustainable and renewable source of energy for the future. Recent significant advances in genetic engineering and fermentation technology have made microbial bio-based production of chemicals from renewable resources more viable. Clostridium species are considered as promising micro-organisms for the production of a wide range of chemicals for industrial use. However, a number of scientific challenges still need to be overcome to facilitate an economically viable production system. These include the use of cheap non-food-based substrates, a better understanding of the metabolic processes involved, improvement of strains through genetic engineering and innovation in process technology. This paper reviews recent developments in these areas, advancing the use of Clostridium within an industrial context especially for the production of biofuels.

An Assessment Of Microalgal Biodiesel With Acetone, Butanol and Ethanol Using LIfe Cycle Assessment (LCA) Methodology

“…This study also does not include the impact associated with the use of replenishment of bacteria for the SSF process. The fused CbCt bacteria are subject to cell immobilization such that replenishment of bacteria occurs infrequently (Dolejš et al, 2014;Green, 2011;Kök, 2016). Eighty two percent of the lignocellulosic biomass is fermented and 49% of the fermented sugar is converted to ABE (Begum & Dahman 2015).…”

Diversity, Function, and Application of Clostridium in Chinese Strong Flavor Baijiu Ecosystem: A Review

“…Diverse metabolic activities of these Clostridium species may be contributing to the complex flavor compounds in SFB, but the detailed formation mechanism is currently unknown. These Clostridium strains can be used as candidates for the industrial production of medium chain fatty acids (Cavalcante et al., ; Diender, Stams, & Sousa, ), alcohols (Ren, Wen, Xu, Jiang, & Gu, ), and other biofuels (Kök, ). Genomics and other systems biology approaches could be used for the comprehensive analysis of physiological characteristics of Clostridium from SFB ecosystem.…”
