  2. Monod equation - Wikipedia

    en.wikipedia.org/wiki/Monod_equation

    μ is the growth rate of a considered microorganism, μ max is the maximum growth rate of this microorganism, [S] is the concentration of the limiting substrate S for growth, K s is the "half-velocity constant"—the value of [S] when μ/μ max = 0.5. μ max and K s are empirical (experimental) coefficients to the Monod equation. They will ...

  3. Butler–Volmer equation - Wikipedia

    en.wikipedia.org/wiki/Butler–Volmer_equation

    In effect, the concentrations are a function of the potential as well. A full treatment, which yields the current as a function of potential only, will be expressed by the extended Butler–Volmer equation, but will require explicit inclusion of mass transfer effects in order to express the concentrations as functions of the potential.

  4. Mass transfer coefficient - Wikipedia

    en.wikipedia.org/wiki/Mass_transfer_coefficient

    The driving force shown here as ' ' is expressed in units of moles per unit of volume, but in some cases the driving force is represented by other measures of concentration with different units. For example, the driving force may be partial pressures when dealing with mass transfer in a gas phase and thus use units of pressure.

  5. Bioconcentration - Wikipedia

    en.wikipedia.org/wiki/Bioconcentration

    The rate at which an organism is exposed through respiratory surfaces and contact with dermal surfaces of the organism, competes against the rate of excretion from an organism. The rate of excretion is a loss of chemical from the respiratory surface, growth dilution, fecal excretion, and metabolic biotransformation. [15]

  6. Deal–Grove model - Wikipedia

    en.wikipedia.org/wiki/Deal–Grove_model

    Given these assumptions, the flux of oxidant through each of the three phases can be expressed in terms of concentrations, material properties, and temperature. = = = where: is the gas-phase transport coefficient, is the concentration of oxidant in the surrounding atmosphere, is the concentration of oxidant in the surface of the oxide, is the concentration of the oxidant at the interface ...

  7. Chemostat - Wikipedia

    en.wikipedia.org/wiki/Chemostat

    The growth rate of the microorganism is controlled by manipulation of the inflow of fresh medium, while the population density is regulated through changing the concentration of the limiting nutrient. This open system allows researchers to maintain the exponential growth phase of cells for use in physiological experiments. [1]

  8. Treadmilling - Wikipedia

    en.wikipedia.org/wiki/Treadmilling

    A cytosolic concentration of subunits below both the C C + and C C − ends results in subunit removal at both ends; Note that the cytosolic concentration of the monomer subunit between the C C + and C C − ends is what is defined as treadmilling in which there is growth at the plus end, and shrinking on the minus end.

  9. Michaelis–Menten kinetics - Wikipedia

    en.wikipedia.org/wiki/Michaelis–Menten_kinetics

    in which e is the concentration of free enzyme (not the total concentration) and x is the concentration of enzyme-substrate complex EA. Conservation of enzyme requires that [28] = where is now the total enzyme concentration. After combining the two expressions some straightforward algebra leads to the following expression for the concentration ...
