Integrated solid-state enzymatic hydrolysis and solid-state fermentation for producing sustainable polyhydroxyalkanoates from low-cost agro-industrial residues

Polyhydroxyalkanoates (PHA) are biodegradable bioplastics of interest as potential substitutes of petroleum-derived plastics that can be produced starting from lignocellulosic-derived residues. This study presents the combined solid-state enzymatic hydrolysis (SSEH) and solid-state fermentation (SSF...
