This work for the first time demonstrates that £]-cyclodextrin (£]-CD) molecules enhance sludge hydrolysis for production of VFAs. With 0.2g£]-CDg -1 dried solids (DSs), the increment rate for VFAs peaked at 4200gg -1DSsg -1 £]-CD, with acetate and propionate as the predominant VFAs. Compositional and microbial community analyses confirm that the £]-CD molecules break a cell's membrane, such that it releases intracellular substances. Although £]-CD molecules inhibited activities of methanogens, they did not impair those of acid-forming bacteria, thereby demonstrating that £]-CD-assisted VFAs are renewable organic carbon sources, except in anaerobic digestion processes. ? 2011 Elsevier Ltd. |
