Sažetak
Solid-state fermentation (SSF) is a technique used for the production of bioactive compounds and also to improve feed values of lignocellulosic wastes and upgrading the values of existing foods. Ganoderma lucidum, white-rot fungus, is a well-known medicinal mushroom used in traditional Chinese medicine for promoting health. It has ability to grow on a different type of substrates and during SSF it produces extracellular enzymes (lignin peroxidase, laccase, cellulase) and degrades lignin and cellulose which leads to formation of valuable compounds. The aim of this work was to investigate the biological treatment of grape pomace (GP) with white-rot fungus Ganoderma l. cultivated in solid-state conditions during fifteen days on the enhancement of phenolic acids content in grape pomace extracts. The biological treatment of GP proved to be a positive technique for recovery of phenolic acids such as gallic acid (GA), protocatechuic acid (PA), syringic acid (SA), vanillic acid (VA), p-hydroxybenzoic acid (p-HBA), p-coumaric acid (p-CuA), ferulic acid (FA) and caffeic acid (CA). Initial concentrations of phenolic acids in GP extracts were 510.59 µg/gdb, 272.01 µg/gdb, 96.47 µg/gdb, 40.61 µg/gdb, 10.95 µg/gdb, 7.40 µg/gdb, 5.95 µg/gdb and 5.33 µg/gdb for GA, PA, SA, VA, p-HBA, p-CuA, FA and CA, respectively. Content of phenolic acids in biologically treated GP was higher up to 2.55- and 2.12-fold after three days of biological treatment for GA and p-HBA. Enhancement of other quantified phenolic acids was observed after one day (1.16-fold for FA), after two days (1.22-, 1.18-, 1.03-fold for SA, VA, CA), after five days (1.64-fold for p-CuA) and after ten days of biological treatment (2.04-fold for PA).
