“…At present, ethanol fermentation technology generally employs batch bioreactor systems and only occasionally continues reactors where the cells are freely suspended in the liquid phase (Choi et al, 2009;Hong et al, 2009;Zhang et al, 2009;Turhan et al, 2010;Ghorbani et al, 2011;Li et al, 2010;Tang et al, 2010) in recent years, many workers have used immobilized-cell systems to ferment a wide variety of carbohydrates to ethanol (Liu et al, 2009;Singh et al, 2009;Pacheco et al, 2010;Ghorbani et al, 2011;Pruksathorn and Vitidsant, 2009) reported that certain strains of S. cerveisiae can undergo up to 10 fermentation cycles using molasses-containing medium. Alshiyab et al (2009) reported that by using bigger reactor size, the effect of gaseous products in fermentation medium was reduced and enhanced both bacterial productivity and biomass concentration, where Brethauer and Wyman (2010) reported that some continuous fermentations are now employed for commercial ethanol production from cane sugar and corn to take advantage of higher volumetric productivity, reduced labor costs, and reduced vessel down time for cleaning and filling.…”

“…Ethanol production via yeast fermentation may provide an economically competitive source of energy (Cysewski and Wilke, 1978;Nguyen et al, 2009;Zhao and Bai, 2009;Csoma et al, 2010;Ding et al, 2010;Dutta et al, 2010;Ibrahim et al, 2010;Jeon and Park, 2010;Oda et al, 2010;Tang et al, 2010;Ghorbani et al, 2011;Razmovski and Vucurovic, 2011). Among the crucial microbial selection and adaptation are: substrate selection and preparation, microbial selection and adaptation optimization of fermentation conditions and improvement of fermentation technology.…”

Problem statement: Some component of fermentation medium showed to reduce the Saccharomyces cerivisae production of ethanol. Approach: This study was designed to evaluate the role of some fermentation parameters in affecting ethanol productivity from beet molasses BM by Saccharomyces cerevisiae CAIM13. Results: Increase in cell concentration (inoculums size) of the yeast above 3.6×105 cells/100 mL decreased the ethanol yield. The yeast could tolerate ethanol concentration up to 10% but failed to grow at concentration of 12 and 15%. Employment of a benchscale tank fermenter enhanced the fermentation efficiency. 77% of BM sugars were assimilated after 48h giving a concentration of 5.4% ethanol. Utilization of a cell-recycling technique showed that the tested organism was capable of performing four fermentation cycles. The mud-free, H 2 SO 4 -treated beet molasses TBM was superior to sucrose in the repeated batch fermentation technique. A continuousflow fermentation technique employing immobilized yeast cells yielded maximum ethanol productivity after 6 days. Conclusion: The present investigation has demonstrated the importance of some fermentation parameters in improving the alcoholic fermentation technology of BM. When free cells of S. cerevisiae. In the case of immobilized cells, the continuous-flow technique speared superior to the repeated batch-fermentation technique in production of alcohol from TBM.

“…They used glucose as the carbon source and from the outcome, it was observed that the substrate and product inhibition had a significant effect on the cell growth as well as succinic acid production (Lin et al, 2008). Similarly, Ghorbani et al (2011) studied the effect of various substrate concentrations on the production of ethanol from molasses using immobilized Saccharomyces cerevisiae. The results showed that the substrate concentration had a significant effect on the rate of ethanol production (Ghorbani et al, 2011).…”

The increase in the price of commercial succinic acid has necessitated the need for its synthesis from waste materials such as glycerol. Glycerol residue is a waste product of Oleochemical production which is cheaply available and a very good source of carbon. The use of immobilized cells can further reduce the overall cost of the production process. This study primarily aims to produce succinic acid from glycerol residue through the use of immobilized Escherichia coli in a batch fermentation process. The parameters which affect bacterial fermentation process such as the mass substrate, temperature, inoculum size and duration of fermentation were screened using One-Factor-At-a-Time (OFAT) method. The result of the screening process shows that a substrate (glycerol) concentration of 30 g, inoculum size 20% v/v, and time 4 h produced the maximum succinic acid concentration of 117.99 g/L. The immobilized cells were found to be stable as well as retain their fermentative ability up to the 6 th cycle of recycling, thereby presenting as an advantage over the free cell system. Therefore, conclude that using immobilized cells can contribute immensely to the cost-effective production of succinic acid from glycerol residue.
