Process for preparation of gallic acid by co-culture

Abstract

A process for the preparation of gallic acid using co-culture comprising providing a tannin-rich mixed substrate and a culture medium in fluid communication with each other, adding an induced innoculum comprising the fungi Rhizopus oryzae and Aspergillus foetidus to the substrate to obtain a fermented mass and gallic acid, extracting the gallic acid from the culture medium and the fermented mass using an organic solvent followed by evaporation of the organic solvent to obtain gallic acid.

Description

technical field [0001] The invention relates to a method for preparing gallic acid through co-cultivation. Background technique [0002] Enzymes are specific proteins of living tissue that function as biocatalysts. Enzymes are capable of performing reactions at normal temperatures and pressures that would require costly energy or not at all at elevated temperatures and / or pressures. That is, the use of enzymes in industry is increasing. [0003] A variety of microorganisms produce extracellular enzymes. They are mainly hydrolases and are primarily concerned with the degradation of macromolecules into units that can be taken up by living cells. Since microorganisms are widely used in the production of enzymes, new methods for the preparation of many important industrial chemicals are constantly being explored. [0004] New developments in the field of biotechnology have resulted in new uses for microbial enzymes. In addition to their traditional use in the food industry ...
