Weed seed survival in an agriculturally-based anaerobic digester
… was undertaken to determine the effects of anaerobic fermentation of raw manure on the viability of Johnsongrass and Fall Panicum seeds which may be present in the waste. Dairy waste containing Johnsongrass and Fall Panicum seeds were subjected to batch and continuously-fed anaerobic …

Development of a Conceptual Framework for Adoption and Sustainable Utilization of Biogas as an Alternative Source of Energy for Emmission
… supply. Energy can also be produced though the anaerobic fermentation of biological waste, such as animal excrement, which is methane-rich. Fermentation also produces a nutrient-rich digestate. Biogas can be used for domestic purposes, such as cooking and heating. Furthermore, it can be …

Comparative analysis of primate hydrogenotrophic microbiota
… disposal of the hydrogen generated during anaerobic fermentation in the human colon is critical to the functioning of this ecosystem. Methanogenesis by methanogenic Archaea and sulfate reduction by sulfate reducing bacteria (SRB) are the major hydrogenotrophic pathways in the human colon. …

Energy and Environmental Tools for Process Sustainability Evaluation
… The first case study is dedicated to the Dark Anaerobic Fermentation in two stages: hydrogen and methane are produced using waste organic materials as substrate. The second one illustrates the comparison between four prototypes of nano-structured heat exchangers and a traditional heat exchanger …

Mesophilic fermentative hydrogen production from sewage biosolids
… of hydrogen production from sewage biosolids via anaerobic fermentation. To do this a number of issues specifically relating to the nature of sewage biosolids had to be addressed. Firstly, the solids content and rheology made automatic feeding difficult. The feedstock also contained high levels of …

Estudio de prefactibilidad para la instalación de una planta productora de biol a partir del estiércol de cuy
… is biol, a liquid fertilizer made through an anaerobic fermentation process, that is, in the absence of oxygen, from a mixture of mainly manure, water, milk and sugar in a biodigester cylinder. The use of guinea pig manure is recommended because it contains more of the main nutrients for …
