Analysis and extension of Gompertz-type and Monod-type equations for estimation of design parameters from batch anaerobic digestion experiments

Effect of dilution and ash supplement on the bio-methane potential of palm oil mill effluent (POME)

“…And compared the experimental data with kinetic models (Modified Gompertz, Schnute, and Monod) showed that the best-fit curve of the Monod model was still high in the digester 2. In addition the solutions for Gompertz-Monod parameter matching in the study of Siripatana et al (2016) [18]. This a model that better to describes microbial activity than those other models, which showed that Monod-type model is more interpretive, giving better insight on the mechanistic explanation of the biogas data.…”

“…Another, more generalized timederivative Gompertz extension, the Schnute model which have the following time derivative of the specific growth rate and the modified form as shown in the Eg. (3) [17][18].…”

Existing Empirical Kinetic Models in Biochemical Methane Potential (BMP) Testing, Their Selection and Numerical Solution

“…The reason for this is these models were originally used to describe the growth of biomass based on initial seeding amount, but not biomethane formation [10]. Thus, some authors [41] suggest a correction to formulas, introducing the bias for zero timepoint at beginning of experiment:…”

Methane production in response to sulfuric acid and hydrogen peroxide assisted hydrothermal pretreatment of sugarcane bagasse

“…Methane production data (Nmmol g -1 TVS) was processed with modified Gompertz model (Zwietering et al, 1990). Modified Gompertz model has been utilized to describe the progress of cumulative CH4 production in batch experiments taking into account relationship between microbial growth and metabolism (Ghasemian et al, 2016;Siripatana et al, 2016;Li et al, 2017).…”
