Synthesis of antioxidant propyl gallate using tannase from Aspergillus niger van Teighem in nonaqueous media.
Tannase from Aspergillus niger van Teighem has been used for synthesis of food additive antioxidant propyl gallate by direct transesterification of tannic acid. The optimized yield of 86% was obtained by using simultaneously pH tuned enzyme, immobilized on Celite and using the right amount of water in the non aqueous media.
متن کاملExpression of Aspergillus oryzae Tannase in Pichia pastoris and Its Application in the Synthesis of Propyl Gallate in Organic Solvent
Gallic acid esters could be synthesized biologically by tannase in organic media, among which is propyl gallate, an antioxidant widely used as a food additive. Efficient intracellular expression of Aspergillus oryzae tannase was achieved in Pichia pastoris under the control of the AOX1 promoter, and the productivity of recombinant tannase was 960 U/L or 64 U/g dry mass. The recombinant P. pasto...

متن کاملTHE SYNTHESIS AND EVALUATION OF NEW DERIVATIVES OF 2,4 DIAMINOPYRIMIDINES WITH MALE CONTRACEPTIVE ACTIVITY
The discovery of the antifertility activity of gossypol led scientists and researchers to the development of compounds with antifertility activity that can be used as male contraceptives. These studies resulted in discovery of the antifertility activity of several classes of compounds which have been reported in the literature. This article deals with the synthesis of four new analogues of pyri...
