Protein hydrolysis and fermentation under methanogenic and

Oct 26, 2019 These findings indicate that amino acid fermentation or deamination could be the rate- step during anaerobic protein degradation. In the present study we explored the hydrolysis and degradation of gelatine as a model dissolved protein under methanogenic and non-methanogenic conditions at a neutral pH, and at a low pH of 5.

Comparison of sludge digestion under aerobic and anaerobic

Jul 01, 2013 Based on the degradation characteristics during anaerobic metabolism, soluble organic matter should consist of simple anaerobic fermentation products formed in the initial stage, such as organic acid. Owing to imbalance between hydrolysis and methanization metabolism, soluble organic matter was accumulated and eventually converted to methane.

pH and Fermentation Weebly

Fermentation is a unique reaction that can be aero-bic (taking place in the presence of oxygen) or anaerobic (taking place in the absence of oxy-gen). There are two main types of fermen-tation that provide the results that humans find beneficial: alcoholic fer-mentation and lactic acid fermentation. Alcoholic fermentation is a reaction

A shift from anaerobic digestion to dark fermentation in

Feb 09, 2021 Anaerobic digestion of aqueous glycol ethylene was tested. The process lasted two cycles of 7 days, but after the second cycle, high hydrogen production occurred shift to dark fermentation. The biogas production lasted 14 days, obtaining peak values of hydrogen, and then rapidly stopped. In investigations, the following were checked: dependence of hydrogen, methane and

Composting to avoid methane production Agriculture and Food

Anaerobic fermentation is common in landfill and open stockpiles such as manure piles. Global emissions from waste have almost doubled since 1970 and now produce 3% of anthropogenic (human origin) emissions (IPCC 2014). About half of these emissions come from the anaerobic fermentation of solid waste disposal on land.

Complete details of biochemistry of anaerobic fermentation process are shown in Fig. 2.4. If acids produced during acid phase are excessive and not fully utilised in other chemical reactions, it retards methane formation. For optimum results, pH of digester contents needs to be maintained between 6.8 and 7.2. Microbiology of Anaerobic Fermentation:

Effect of the Ca2+ concentration on anaerobic digestion

After 11 days of fermentation, the pH of the fermentation broth in each of the anaerobic bottles remained below 6.6, which would increase the lag of methane production at this lower pH range (Hao et al. 2012). However, the pH of the fermentation broth at this point is within the appropriate pH range for hydrolytic acidification.
