Clostridium beijerinckii BA101 mutant fermentation time course

Project description:The fermentation culture of Clostridium beijerinckii mutant BA101 was monitored from exponential growth to stationary phase. During this period the culture underwent a shift from acidogenesis to solventogenesis. Acetone and butanol production was initiated with the onset of the solventogenic phase. Using DNA microarray changes in gene expression were examined during the transitional period. RNA samples were taken from Clostridium beijerinckii mutant BA101 fermentation culture at individual time points during the acidogenic phase and the solventogenic phase. The samples were used for microarray hybridization.

Calcium effect to the Clostridium beijerinckii NCIMB 8052 degenerate strain for the solvent producing recovery

Project description:Solventogenic Clostridium species ferment carbohydrates to acetone, butanol and ethanol which are well-known next-generation biofuels. However, repeated subculture of or continuous fermentation by Clostridium often decreases and eventually terminates the solvent production and spore formation, which is a process called strain degeneration. Supplementation of CaCO3 to fermentation medium could partially recover metabolism of degenerated strain by more than 50% increase of cell growth and solvent production. The transcriptome profile of Clostridium beijerinckii NCIMB 8052 (DG-8052) and its response to CaCO3 treatment were analysed by microarray. Since fermentation by C. beijerinckii NCIMB 8052 is a biphasic process, gene expressions of two fermentations were compared at each stage, i.e. 12h and 24h fermentation time representing acidogenic phase and solventogenic phase, respectively. This study examined expression of 5168 genes capturing 98.6% of the C. beijerinckii NCIMB 8052 genome. With the addition of CaCO3, DG-8052 had 565 and 916 genes significantly up-regulated at acidogenic phase and solventogenic phase, respectively. According to the enrichment analysis of pathway and Gene Ontology terms and Kyoto Encyclopedia of Genes and Genomes (KEGG) pathway, these genes were significantly overrepresented in cellular functions such as Amino acid transport and metabolism, organic acid biosynthetic process, bacteria chemotaxis and defense mechanisms. On the other hand, there were 704 and 1044 genes significantly down-regulated at acidogenic phase and solventogenic phase, respectively. These repressed genes were mainly enriched in functions such as ion transmembrane transport, ATP synthesis, oxidative phosphorylation.

Effect of furfural on the Clostridium beijerinckii NCIMB 8052 transcriptome

Project description:Furfural is the prevalent microbial inhibitor generated during pretreatment and hydrolysis of lignocellulosic biomass to monomeric sugars, but the molecular response of Clostridium beijerinckii NCIMB 8052 to this compound is unknown. To discern the effect of furfural on C. beijerinckii and to gain insights into the molecular mechanisms of action and detoxification, we studied the physiological changes of furfural-stressed cultures during acetone-butanol-ethanol (ABE) fermentation, and profiled differentially expressed genes by genome-wide transcriptional analysis. C. beijerinckii exposed to furfural stress during the acidogenic growth phase produced 13% more ABE than the unstressed control. The growth and ABE by C. beijerinckii ceased following exposure to furfural stress during the solventogenic growth phase. By comparing gene expression of furfural-stressed cultures to that of the unstressed control, at both the acidogenic and solventogenic phases, we ascertained that furfural induces expression of several genes including those that code for heat shock proteins, redox enzymes and cofactor associated proteins, and ATP-binding cassette transporters, and represses genes belonging to the phosphotransferase system, two-component system, chemotaxis and cell motility. Based on these results, we discuss the underpinning for furfural-mediated change in ABE fermentation by the solventogenic Clostridium species.

Clostridium beijerinckii NCIMB8052 wild-type cells vs.Clostridium beijerinckii NCIMB8052 degenerated strain cells

Project description:The transcriptome analysis by microarray was applied on wild-type and degenerated strains of C. beijerinckii NCIMB8052 (WT-8052 and DG-8052, respectively) to elucidate its mechanism of degeneration during solvent fermentation. The comparison of gene expression pattern in relation to ABE production is expected to provide insights toward metabolically engineering of C. beijerinckii NCIMB8052 with prevention of degeneration and eventually enhancement of ABE production.
