GC-MS analysis of AP-bio-oil components before and after fermentation. a: fermentation medium with 50% AP-bio-oil; b: fermentation medium with 100% AP-bio-oil. Peaks for possible components: 1:3-methyl-butanal; 2: ethanol; 3: acetic acid 4: 2, 3-dihydro-3, 5-dihydroxy-6-methyl-4H-Pyran-4-one; 5: dimethoxy phenol.
