dc.description.abstract | Anaerobic digestion of raw chicken feather waste and its co-digestion with poultry litter were assessed in batch assays. Following, two strategies were evaluated to improve methane production from chicken feathers: (i) waste pre-hydrolysis through thermochemical treatment using lime and sodium hydroxide, and (ii) amendment of digestion broth with the proteolytic bacterium Fervidobacterium pennivorans. Anaerobic digestion of the raw waste (2.5% total solids) allowed a specific methane production of 123 ± 3 L CH4 kg 1 VS. Pre-treatment and bioaugmentation strategies did not improve methane production from feather waste, despite the significant increase in waste solubilisation, from 45 ± 5% up to 64 ± 1% using F. pennivorans and up to 96% after pre-treatment with 2 g NaOH g 1 waste. These results indicate that conversion of soluble organic matter to methane, and not the hydrolysis rate, was the limiting step for the anaerobic digestion of chicken feather waste. | por |
dc.description.sponsorship | The authors are very grateful to Prof. Madalena Alves for all the scientific support, fruitful discussion, and critical reading of the manuscript. The help given by Dr. Isabel Belo with the high-pressure reactor used for waste thermochemical pre-treatment is also kindly acknowledged. The Portuguese Science Foundation (FCT) and the European Social Fund (ESF, POPH-QREN) gave financial support through the Post-Doctoral Grant attributed to Jose Carlos Costa (SFRH/BDP/48962/2008), and by the ESF within the National Strategic Reference Framework (NSRF-QREN) program under Contract No. 2509. | por |
