Abstract/OtherAbstract:
The highest enzymatic extraction of covalent linked chlorogenic (36.1%) and caffeic (33%) acids from coffee pulp was achieved by solid-state fermentation with a mixture of three enzymatic extracts produced by Aspergillus tamarii, Rhizomucor pusillus and Trametes sp. Enzyme extracts were produced in a practical inexpensive way. Synergistic effects on the extraction yield were observed when more than one enzyme extract was used. In addition, biotransformation of chlorogenic acid by A. niger C23308 was studied. Equimolar transformation of chlorogenic acid into caffeic and quinic acids was observed during the first 36 h in submerged culture. Subsequently, after 36 h, equimolar transformation of caffeic acid into protocatechuic acid was observed; this pathway is being reported for the first time for A. niger. Quinic acid was used as a carbon source by A. niger C23308. This study presents the potential of using coffee pulp to produce enzymes and compounds such as chlorogenic acid with biological activities. © 2013 American Institute of Chemical Engineers Biotechnol.
