Immobilization of yeast cells on hydrogel carriers obtained by radiation-induced polymerization

Yeast-laden hydrogel capsules for scalable trace lead removal from water

“…[29][30][31] Hence, encapsulating yeast inside hydrogels is expected not to impose signicant kinetic limitations on the treatment process compared to using free yeast cells in water. Furthermore, a signicant body of work in the eld of bioengineering demonstrates that hydrogels can be made using chemistries compatible with yeast cells, 32,33 implying minimal functionaffecting interactions between the cells and the surrounding hydrogel matrix. Therefore, it can be expected that encapsulating yeast cells within hydrogel particles will not signicantly affect yeast-lead interactions.…”

Gel Entrapment and Micro-Encapsulation: Methods, Applications and Engineering Principles

“…The polymeric matrices were swollen in water and then aerobically incubated with yeast cells. High ethanol productivities could be obtained by batch (Fujimura et al, 1988;Xin et al, 1992;Carenza et al, 1993) as well as by continuous fermentation (Carenza et al, 1989; Poly(ethylene glycol) dimethacrylate was also used as a cross-linking agent for the entrapment of biocatalysts by radical polymerisation of acrylic acid and N,Ndimethylaminoethyl methacrylate (Sakata et al, 1981).…”

“…Low temperature (-78°C) radiation polymerisation has proven to be fruitful to prepare porous hydrogels for entrapment of yeast cells (Carenza and Veronese, 1994). Aqueous solutions of a wide variety of monomers (Carenza et al, 1990; or comonomers (Fujimura et al, 1988;Carenza et al, 1989;Xin et al, 1992) have been used. The polymeric matrices were swollen in water and then aerobically incubated with yeast cells.…”
