Bioreactors with immobilized lipases: state of the art.
This review attempts to provide an updated compilation of studies reported in the literature pertaining to reactors containing lipases in immobilized forms, in a way that helps the reader direct a bibliographic search and develop an integrated perspective of the subject. Highlights are given to industrial applications of lipases (including control and economic considerations), as well as to met...
متن کاملGreen biosynthesis of floxuridine by immobilized microorganisms.
This work describes an efficient, simple, and green bioprocess for obtaining 5-halogenated pyrimidine nucleosides from thymidine by transglycosylation using whole cells. Biosynthesis of 5-fluoro-2'-deoxyuridine (floxuridine) was achieved by free and immobilized Aeromonas salmonicida ATCC 27013 with an 80% and 65% conversion occurring in 1 h, respectively. The immobilized biocatalyst was stable ...
متن کاملHydrolysis of lactose by immobilized microorganisms.
Cells of Lactobacillus bulgaricus, Escherichia coli, and Kluyveromyces (Saccharomyces) lactis immobilized in polyacrylamide gel beads retained 27 to 61% of the beta-galactosidase activity of intact cells. Optimum temperature and pH and thermostability of these microbial beta-galactosidases were negligibly affected by the immobilization. Km values of beta-galactosidase in immobilized cells of L....
متن کاملBiodegradation of phenols and cyanides using membranes with immobilized microorganisms
The immobilization of microorganisms on ultrafiltration membranes made from polyacrylonitrile modified chemically with hydrazine hydrate and glutaraldehyde and their application to the biodegradation of phenol and cyanide contained in industrial wastewaters was examined. Three types of microorganism isolated from a mixed population of activated sludge adapted to phenol and cyanide decomposition...
