Entrapment of viable microorganisms by SiO2 sol-gel layers on glass surfaces: trapping, catalytic performance and immobilization durability of Saccharomyces cerevisiae.
TLDR
The trapped biocatalyst survives experimental working-up and displays kinetic behavior excluding mass transport interference during sucrose degradation, attributed to the mechanical features of this film, which displays a tensile strength sufficient to contrast the tensile stress exerted by cell reproduction.About:
