WebResults indicated that the β‐glucosidase of P. oxalicum can be considered as a very promising catalyst for the synthesis of salidroside. A glycoside hydrolase from Penicillium oxalicum BL 3005 was purified to apparent homogeneity. Its molecular mass was estimated to be 90 kDa by SDS‐PAGE. The enzyme was identified to be a new member of family‐3 … WebPolyphenolic esters (PEs) are valuable chemical compounds that display a wide spectrum of activities (e.g., anti-oxidative effects). As a result, their production through catalytic routes is an attractive field of research. The present review aims to discuss recent studies from the literature regarding the catalytic production of PEs from biomass feedstocks, namely, …
