PHYTASE PRODUCTION BY Aspergillus niger AND Aspergillus terreus IN SOLID STATE FERMENTATION USING WHEAT BRAN
Animal nutrition industry demands for phytases with high specific activity and stability under high temperature conditions (feed pellet production) and under acidic conditions (monogastric animals), for this reason continues to stimulate the search for new enzyme sources [1]. Most of scientific work has been focused on Aspergillus spp. phytases due to their biochemical properties found [2]. An ...
متن کاملTOPIC: Food Enzymology FE-14 Phytase Production By Aspergillus niger And Aspergillus terreus In Solid State Fermentation Using Wheat Bran
Phytases have been one of the focal enzymes for animal nutrition during the past two decades. In this work, the use of wheat bran as substrate for phytase production in Solid State Fermentation (SSF) was studied. In order to find the best fermentation conditions for phytase production using a laboratory strain indentified as Aspergillus niger, three different pretreatments (1: wheat bran withou...
متن کامل(+)-Geodin from Aspergillus terreus.
The fungal metabolite (+)-geodin [systematic name: (2R)-methyl 5,7-dichloro-4-hydroxy-6'-methoxy-6-methyl-3,4'-dioxospiro[benzofuran-2,1'-cyclohexa-2',5'-diene]-2'-carboxylate], C(17)H(12)Cl(2)O(7), was isolated from Aspergillus terreus. The crystal structure contains two independent molecules in the asymmetric unit. Molecules denoted 1 interact through O-H...O hydrogen bonds creating chains of...
متن کاملButyrolactones from Aspergillus terreus.
In the process development of lovastatin using Aspergillus terreus DRCC 152 in solid state fermentation, we have isolated a new butyrolactone-IV (3) along with the previously reported butyrolactone-I (1) and butyrolactone-II (2) produced under submerged conditions. The structure of compound 3 has been characterized as 3-hydroxy-5-[2-(1-hydroxy-1-methylethyl)-2(R)-2,3-dihydro-benzo[b]furan- 5 yl...
متن کاملPSA Nutrition: Phytase
Both 1,25-dihidroxyvitamin D3 and phytase are known to improve phosphorus utilization in broilers(Biehl and Baker,J Nutr 1997). Solanum glaucophyllum(Sg) is a plant containing high amounts of 1,25dihydroxyvitamin D bound to a glycoside. It may be an economical source of 1,25-dihydroxyvitamin D for animal feeds. We examined the effect of Sg, with and without phytase, on phosphorus utilization in...
