Biological valorization strategy for converting spent coffee grounds into biopolymers and chemicals

Popis výsledku v původním jazyce

Coffee is the second largest traded commodity in the world. More than 6 million tons of spent coffee grounds (SCG) per year are generating worldwide as a solid residue after beverage preparation or instant coffee production [1]. In the time when we should save carbon sources and use the carbon only we have to, SCG belong to valuable renewable sources of carbon. This work suggests a biological valorization strategy for converting of SCG into polyhydroxyalkanoates (PHA), lactic acid, carotenoids, antioxidants, antimicrobial agents, and filler for polymers [2 - 4]. For the suggested approach, the fractionation of SCG is a crucial step. For the biotechnological production of PHA, oil derived from SCG after extraction with n-hexane as well as fermentable sugar derived from SCG through hydrolysis have been used. SCG hydrolysates have been detoxified through an adsorption strategy by using Amberlite XAD4. Amberlite XAD4 is a non-ionic crosslinked polymer, which adsorptive properties are connected with its ma
