A revised monod-type rate law predicting variable sulfur isotope fractionation factors as a function of microbial sulfate reduction rate
… relationship through the use of a modified Monod-type rate expression constrained by a novel set of experiments. A series of batch reactors containing an identical amount Desulfovibrio vulgaris, a strain of sulfate reducing bacteria (SRB), were subjected to differing continuous mass addition …

Kinetics of Microbial Respiration
… have relied on empirical relations, such as the Monod and dual-Monod equations, which do not consider how energy available in cell's environment or the accumulation of reaction products affects respiration rate. I derive a new rate law on the basis of nonlinear nonequilibrium thermodynamics and …

Novel application of quantitative risk assessment modelling to a continuous fermenter
… anaerobic fermenter based on widely employed Monod process model.

Mathematical Modeling and Scanning Electron Microscopic Study of Biofilm on Adsorptive Media (Orthogonal Collocation Method)
… fundamental mechanisms, including film transfer, Monod kinetics, biofilm growth, and shear loss, was derived to describe performance of biofilm attached to an adsorbing surface. The model-BFAC model-has three features: substrate diffuses in a growing biofilm (moving boundary problem); the reaction …

A model-based approach for the development of a bioelectrochemical sensor for biochemical oxygen demand in wastewater
… using low scan cyclic voltammetry. In terms of Monod kinetics, the anode potential determines the limitation placed on microbial respiration rate by the affinity of the electron acceptor for electrons, and is analogous to the effect of oxygen concentration on growth rate in an aerobic system. …

Substrate interactions during the anaerobic biodegradation of 1,1,1-trichloroethane
… of the electron donor and acceptor. Although Monod kinetics adequately described the relationship between TCA concentration and its biodegradation rate, the Monod kinetic parameters were functions of the concentrations of the primary electron donor and acceptor. The apparent maximum specific …

Kinetic Modeling of Mesophilic Digestion of Swine Manure Containing an Antibiotic Inhibitor (Methane, Biogas)
… study was conducted to investigate the Monod kinetic parameters associated with the design and operation of mesophilic digestion of swine manure containing the antibiotic chlortetracycline (CTC). The experimental design was set up to determine the effects retention time (RT) and …

Modeling the biodegradation kinetics of dissolved organic contaminants in a heterogeneous two-dimensional aquifer
… can be changed. The differences between the Monod and biofilm kinetic models were shown to be negligible by model simulations and dimensionless analysis for realistic groundwater parameter ranges.

Microbial CR(VI) reduction in indigenous culture of bacteria: characterization and modelling
… sludge treatment process at the source. A Monod like model was used to evaluate the rate of Cr(VI) reduction over a wide range of initial Cr(VI) concentrations. The model revealed that Cr(VI) reduction in the consortium culture followed quasi-first order kinetics with a Cr(VI) inhibitor …

Numerical Modeling Of Dissimilatory Iron Reduction In Sediments At A Field Site
… on the results of simulations, only the dual Monod kinetic with inhibition rate formulation with respect to the concentrations of lactate, ßFeOOH, and Fe2+ under certain initial concentration of dissimilatory metal-reducing bacterium could fit the experimental data well. Our results also …

The Influence of Nucleic Acids of Yolk Origin on the Growth and Development of the Avian Yolk Sac
… control of development even though the Jacob and Monod theories have explained many of the details of gene action. The long standing paradox of DNA constancy vs.specificity of gene products still remains unresolved. Even if one takes the view that specific steps in development are dependent only …

Development of Kinetic Parameterization Methods for Nitrifying Bacteria using Respirometry
… system. A forward model was developed based on Monod kinetics to simultaneously fit Monod curves to the experimental OUR data. These curves were fit by solving for optimum oxygen kinetic parameters representing endogenous respiration, NOB, and AOB. An inverse model using Markov chain Monte Carlo …

Sediment Oxygen Demand Kinetics
… applicability of zero-order, first-order, and Monod kinetics to describe transient and steady state SOD was modeled using analytical and numerical techniques. Field and laboratory experiments suggested that first-order kinetics characterize Carvin's Cove SOD. SOD calculated from field …

Modeling of Biological Activity in Expanded-Bed, Anaerobic Activated Carbon Filters
… mass transport, biofilm molecular diffusion, and Monod kinetics were incorporated in developing the models. Acetate was the single-stage substrate studied while phenol was examined in parallel and modeled as the two-stage substrate. After 849 days of continuous operation, four steady-state …

Comparison of optical density, total cell protein, and number of viable cells (via fluorescent straining) as measures of microbial growth kinetics in suspended and biofilm cultures during biodegradation of naphthalene
… Inclusion of a lag time in the integrated Monod expression improved the agreement between experimental and calculated values of biomass and naphthalene concentrations. However, further improvements will require more detailed kinetics of the actual biochemical pathway.
