چکیده انگلیسی
Digestate from biowaste was assessed as a potential source of bioproducts of commercial and industrial interest through solid-state fermentation. The targeted bioproducts were hydrolytic enzymes (cellulases and proteases from autochthonous microbiome), biosurfactants (sophorolipids produced from Starmella bombicola) and biopesticides (produced from Bacillus thuringiensis). Low cellulase production was observed within the range of 0.5-1.5â¯FPUâ¯gâ1 DM while protease production showed two discrete peaks of 66â¯Â±â¯8 and 65â¯Â±â¯3â¯Uâ¯gâ1 DM at 3.5 and 48â¯h, respectively. Low sophorolipids production was also obtained, with a maximum yield of 0.02â¯gâ¯gâ1 DM using hygienised digestate supplemented with external sugar and fat sources. Biopesticides produced by B. thuringiensis were successfully at 72â¯h of operation, reaching a maximum spore production of 8.15â¯Â±â¯0.04 (107) CFU gâ1 DM and 2.85â¯Â±â¯0.22 (107) CFU gâ1 DM using sterile and hygienised digestate, respectively. These biopesticides could contribute to the substitution of chemically produced pesticides, moving towards a sustainable digestate management in a circular economy scheme.
