A description of hydrolysis kinetics in anaerobic degradation of particulate organic matter

The Research of Corrected First Order Kinetics on Hydrolysis and Biogas Generation in Batch Anaerobic Digestion

“…It is believed that the hydrolysis is basically unrestricted from diffusion for kitchen waste with a size of 10 mm. Vavilin proposed hydrolysis rate equation for particulates with different shapes [23]. This equation is consistent with corrected first order model proposed by Liu [24].…”

Kinetic Modeling of Mixed Culture Process of Anaerobic Co-digestion of Vegetable Wastes with Pistia stratiotes: A Scientific Attempt on Biomethanationy

“…This is the fastest step of the anaerobic conversion of complex organic matter. Thus, changes in acidogenic rate constants do not influence the methane production rate [35]. However, acetic acid which is the major precursor for methane formation is produced through acetogenesis pathway where in which the organic acids serve as substrate for acetogenic bacteria.…”

“…Hydrolysis is the rate limiting step in most of the anaerobic digestion process with certain exceptions where methanogenesis is reported to be limiting [35]. Hydrolysis of particulate substrate into simpler molecules aids in easy transport into the cell for its further metabolism.…”

Innovative pretreatment strategies for biogas production

“…This step has been reported to be the fastest step in the AD process (Vavilin et al, 1996). If the feedstock has a low buffering capacity and the organic loading rate is high, the accumulation of volatile fatty acids can result in a pH drop, which would inhibit the methanogens that produce methane in the final step.…”
