Optimization of methane fermentation of agricultural waste

Accumulation of environmentally hazardous agricultural waste, in particular cow manure without the proper treatment, creates an ecological threat to environment. During energy crisis, search for alternative pathways obtain is also one most urgent issues today. Cow promising as a substrate anaerobic fermentation with production valuable carrier — methane. Fermentation sole not spread. It takes place due low efficiency process. We hypothesized that caused by inhibition microbiome end products gastrointestinal tract cows and non-optimal conditions microbial growth. Thus, goal work was develop approach methane using conversion succession its effective degradation obtaining carrier. The following methods were used: potentiometric measurement pH Eh, chromatographic determination composition gas phase. To study patterns manure, treatments analyzed: 1. autochthonous microtome regulation medium; 2. addition fermented sludge tank inoculum regulation; 3. via adding regulation. As result, shown be inefficient. In this case, yield only 20 L/kg substrate. suggested take accumulation fermentation. Conversion succession, i.e., replacement microbiome, introduction biomass tank, provided increase 230 This result testifies application another methanogenic useful compounds inhibited serve introduced one. allowed creating optimal growth microorganisms increased 280 So, change i.e. made it possible 14-fold manure. carrier, obtained results can basis further development environmental biotechnologies.
