“…The compositions in terms of cellulose, hemicellulose, and lignin in those lignocellulosic feedstock were represented by Menon and Rao (2012) and Van Dyk and Pletschke (2012). The substrates that are mainly used for membrane technology-based bioethanol production are mainly pure and expensive carbohydrate sources such as glucose, fructose, sucrose, and lactose (Cheryan and Mehaia 1983, Hoffmann et al 1985, Melzoch et al 1991, Ding et al 2012, industrial waste (whey and molasses), and sludge-based materials (Mehaia and Cheryan 1990, Tin and Mawson 1993, Kaseno and Kokugan 1997, Lee and Yeom 2007. Time-consuming and expensive pretreatment processes are the main prerequisites to avoid membrane fouling while working with waste materials.…”

“…For that, the judicious selection, combination, and integration among microfiltration (MF), ultrafiltration (UF), and nanofiltration (NF) processes have been formulated by different researchers to make the overall process continuous, compact, and successful. The most widely used carbon sources for membrane reactor-based bioethanol production process have been pure and expensive carbohydrate sources such as glucose, fructose, sucrose, and lactose (Cheryan and Mehaia 1983, Hoffmann et al 1985, Melzoch et al 1991, Ding et al 2012 and industrial wastes such as whey, molasses, and sludge-based materials (Mehaia and Cheryan 1990, Tin and Mawson 1993, Kaseno and Kokugan 1997, Lee and Yeom 2007. Such waste substrates demanded time and expensive pretreatment strategies to avoid membrane fouling.…”

AbstractTo meet the worldwide rapid growth of industrialization and population, the demand for the production of bioethanol as an alternative green biofuel is gaining significant prominence. The bioethanol production process is still considered one of the largest energy-consuming processes and is challenging due to the limited effectiveness of conventional pretreatment processes, saccharification processes, and extreme use of electricity in common fermentation and purification processes. Thus, it became necessary to improve the bioethanol production process through reduced energy requirements. Membrane-based separation technologies have already gained attention due to their reduced energy requirements, investment in lower labor costs, lower space requirements, and wide flexibility in operations. For the selective conversion of biomasses to bioethanol, membrane bioreactors are specifically well suited. Advanced membrane-integrated processes can effectively contribute to different stages of bioethanol production processes, including enzymatic saccharification, concentrating feed solutions for fermentation, improving pretreatment processes, and finally purification processes. Advanced membrane-integrated simultaneous saccharification, filtration, and fermentation strategies consisting of ultrafiltration-based enzyme recycle system with nanofiltration-based high-density cell recycle fermentation system or the combination of high-density cell recycle fermentation system with membrane pervaporation or distillation can definitely contribute to the development of the most efficient and economically sustainable second-generation bioethanol production process.

“…In our previous works, the conception on a continuous and closed-circulating fermentation (CCCF) process was proposed, and a lot of experimental evidences have been disclosed (Chen et al, 2012;Ding et al, 2011Ding et al, , 2012. In this process, ethanol inhibition could be eliminated owing to simultaneous ethanol removal by the membrane pervaporation, so that long fermentation period could be maintained and then high amount of ethanol production could be accomplished.…”

Acetone-butanol-ethanol fermentation using Clostridium acetobutylicum was studied in the continuous and closed-circulating fermentation (CCCF) system. The experiment lasting for 192 H was carried out by integrating fermentation with in situ pervaporation. In the entire process, the cell growth profile took place in the following two phases: the logarithmic phase during early 28 H and the linear phase from 130 to 150 H. This was a unique characteristic compared with the curve of traditional fermentation, and the fitting equations of two growth phases were obtained by Origin software according to the kinetic model of cell growth. Besides, the kinetic parameters that include the butanol yield, maximum specific growth rate, average specific formation rate, and volumetric productivity of butanol were measured as 0.19 g g(-1) , 0.345 H(-1) , 0.134 H(-1) and 0.23 g L(-1) H(-1) , respectively. The C. acetobutylicum in the CCCF system showed good adaptability and fermentation performance, and the prolonged fermentation period and high production were also the main advantages of CCCF technology.
