Improvement of solid-state anaerobic digestion of broiler farm-derived waste via fungal pretreatment.

Fungus, Trichoderma longibrachiatum, was used for the pretreatment of broiler farm derived-lignocellulosic bedding material (rice husk) to enhance the subsequent solid-state anaerobic digestion (SS-AD). Fungal pretreatment efficacy was evaluated through a series of batch studies with respect to carbon-to-nitrogen (C/N) ratio and pretreatment time. Lignocellulosic outer layer structure disruption of the rice husk was prominent under the best fungal pretreatment condition evaluated (C/N ratio of 18.

Holistic determination of suitable conditions for biogas production from Pennisetum purpureum x Pennisetum americanum liquor in anaerobic baffled reactor.

Holistic approach had been undertaken to determine the suitable conditions for biogas production from Pennisetum purpureum x Pennisetum americanum (Napier Pak Chong1) liquor using the anaerobic baffled reactor (ABR). Effects of factors, i.e.
