Influence of innoculum acclimation in the biodegradation rate and estimated biodegradbility of cow manure, food waste and oil Autori: Lucia Neves, Maria Madalena Alves, Raquel Ferreira, Rosario OliveiraData aparitiei: March 2010 Revista: Environmental Engineering and Management Journal › Vol. 9 › Nr. 3 ISSN: 1843 - 3707 Format PDF Abstract
Two different inocula - acclimated and non-acclimated to fat- were used to evaluate the methane production of cow manure, food waste and oily waste in batch assays. The inoculum adapted to fat had a better performance in the methanisation of substrates with significant lipids content. Furthermore, it is demonstrated that an increase in the ratio inoculum/substrate can enhance the initial methane production rate of oily waste when using a non-adapted inoculum, improving also the ultimate methane production.
Additionally, this work also revels that changing from mesophilic to thermophilic temperature conditions an inoculum can overcome adaptation setbacks to a substrate, while another one, that displayed good mesophilic performance, can become unproductive. As the results demonstrate, the microbial consortium present in each inoculum can bring about different outcomes while degrading different organic wastes, especially in anaerobic digestion of oily waste.
