“…In order to eliminate this problem, the implementation of suitable immobilization techniques, e.g., adsorption or entrapment of the cells on or in inert material, may be performed. There are very limited studies with immobilized cell systems for 1,3-PDO production [5][6][7].…”

The continuous production of 1,3-propanediol (1,3-PDO) was investigated with Clostridium beijerinckii NRRL B-593 using raw glycerol without purification obtained from a biodiesel production process. Ceramic rings and pumice stones were used for cell immobilization in a packed-bed bioreactor. For comparison purpose, a control bioreactor with suspended culture was also run. The effect of hydraulic retention time (HRT) on the production of 1,3-PDO in both immobilized and suspended bioreactors were also investigated. The study revealed that HRT is an important factor for both immobilized and suspended systems and a HRT of 2 h is the best one in terms of volumetric production rate (g 1,3-PDO/L/h). Furthermore, cell immobilization had also obvious benefits especially for the robustness and the reliability of the production. The results indicated that cell immobilization achieved a 2.5-fold higher productivity in comparison to suspended cell system. Based on our results, continuous production of 1,3-PDO with immobilized cells is an efficient method, and raw glycerol can be utilized without any pretreatment.

“…Among them, polyvinyl alcohol (PVA) outstands by offering many advantages (Cattorini et al., ; Durieux, Nicolay, & Simon, ; Illanes, ; Liu, Chen, & Shi, ; Lozinsky & Plieva, ; Porto et al., ). So, PVA has been thoroughly used for cell immobilization (Durieux et al., ; El‐Naas, Mourad, & Surkatti, ; Lozinsky & Plieva, ; Nonthasen, Piyatheerawong, & Thanonkeo, ; Rebroš, Rosenberg, Stloukal, & Krištofíková, ; Wittlich, Capan, Schlieker, Vorlop, & Jahnz, ; Zhu et al., ). However, enzyme leaching out of the matrix is a major drawback, which can be avoided by encapasulation of the previously crosslinked enzyme, as illustated by the case of pencillin acylase immobilization (Wilson et al., ).…”

Enzymes are powerful catalysts already being used in a large number of industrial processes. Impressive advantages in enzyme catalysts improvement have occurred in recent years aiming to improve their performance under harsh operation conditions far away from those of their cellular habitat. Production levels of the winemaking industry have experienced a remarkable increase, and technological innovations have been introduced for increasing the efficiency at different process steps or for improving wine quality, which is a key issue in this industry. Enzymes, such as pectinases and proteases, have been traditionally used, and others, such as glycosidases, have been more recently introduced in the modern wine industry, and many dedicated studies refer to the improvement of enzyme performance under winemaking conditions. Within this framework, a thorough review on the role of enzymes in winemaking is presented, with special emphasis on the use of immobilized enzymes as a significant strategy for catalyst improvement within an industry in which enzymes play important roles that are to be reinforced paralleling innovation.

“…For example, new immobilization technology based on lens-shaped particles ( Fig. 17.5) [20] was adapted for production of ethanol from molasses in cooperation with the company BMA-Starcosa (Braunschweig, Germany). Continuous and stable ethanol production from untreated molasses was achieved over several months, even under nonsterile conditions.…”
