Originální abstrakt
Spent coffee grounds (SCG) represent solid waste generated by coffee processing industries. Their disposal represents a serious environmental problem; however, SCG can be valorised within a biorefinery concept yielding various valuable products. This work investigates the potential conversion of SCG into lactic acid (LA). SCG were hydrolysed by combination of dilute acid treatment and subsequent application of cellulase. The SCG hydrolysate contained a considerable amount of reducing sugars (9.02 ± 0.03 g/l glucose; 26.49 ± 0.10 g/l galactose + mannose and 2.81 ± 0.07 g/l arabinose) and it was used as a substrate for cultivation of Lactobacillus plantarum CCM 7039T. Despite the inhibitory effect exerted by furfural and phenolic compounds in the medium, reasonably high lactic acid concentrations (33.53 ± 0.73 g/l) and yields (98 %) were gained. Therefore, it could be demonstrated that SCG is a promising raw material for the production of lactic acid and could serve as a feedstock for the sustainable large-scale production of lactic acid.
