Anaerobic Degradation of Halophyte Biomass for Biogas Production
Anaerobic degradation of wild halophytes (Kalidium caspicum, Salicornia europaea and Climacoptera lanata) from solonchaks of Kyzylkum desert in comparison with conventional glycophyte Panicum coloratum was studied. Lab-scale reactors were fed with dried and milled plant biomass. Tests were operated under batch and continuous mode at mesophilic (M) and thermophilic (T) temperatures. High concent...
متن کاملStudy of Diverse Methanogenic and Non-methanogenic Bacteria Used for the Enhancement of Biogas Production
To achieve a functioning and stable process with high methane production, it is important to create and maintain a beneficial environment for the activity of bacterial consortia of suitable species. Therefore, an experiment has been carried out to isolate methanogenic and nonmethanogenic bacteria from anaerobic biogas system. With this view, a microbial consortium and their relative performance...
متن کاملPolyphasic analyses of methanogenic archaeal communities in agricultural biogas plants.
Knowledge of the microbial consortia participating in the generation of biogas, especially in methane formation, is still limited. To overcome this limitation, the methanogenic archaeal communities in six full-scale biogas plants supplied with different liquid manures and renewable raw materials as substrates were analyzed by a polyphasic approach. Fluorescence in situ hybridization (FISH) was ...
متن کاملSyntrophic associations in methanogenic degradation.
For many decades, microbiology has tried to understand the activities of microorganisms in nature on the basis of pure culture studies which allow reliable identification of the actors in play and reproducible assessments of their activities under defined conditions. This approach has undoubtedly been successful, but it has overlooked that microbes in nature interact with each other and may dep...
متن کاملEnergetics of syntrophic cooperation in methanogenic degradation.
Fatty acids and alcohols are key intermediates in the methanogenic degradation of organic matter, e.g., in anaerobic sewage sludge digestors or freshwater lake sediments. They are produced by classical fermenting bacteria for disposal of electrons derived in simultaneous substrate oxidations. Methanogenic bacteria can degrade primarily only one-carbon compounds. Therefore, acetate, propionate, ...
