WHY POLYPHENOLS PRESENT IN SPENT COFFEE GROUNDS INHIBIT THE GROWTH OF BACTERIA PRODUCING POLYHYDROXYALKANOATES?
Original language description
Our study aims at suggesting detoxification methodology, which would enable to extract phenolic compounds from spent coffee grounds (SCGs) hydrolysates to produce inhibitor-free hydrolysates. SCGs arise as a waste product through the production of instant coffee and coffee brewing. SCGs contain an oil fraction and a lignocellulosic fraction, which can be used as a carbon substrate for bacteria producing polyhydroxyalkanoates (PHA). Fermentable sugars are transformed from SCGs via chemical hydrolysis. However, SCG hydrolysates contain also phenolic compounds, which are too toxic for PHA producing bacteria and partially even completely inhibit their growth. Our results showed that the multi-stepped extractions' methodology enabled to extract phenolic compounds and produce inhibitor-free SCG hydrolysates from which may profit PHA producing bacteria. Moreover, extracted phenolics reveal high antimicrobial activity, and therefore, they can be used in numerous high-value applications.
