Microorganisms concentration

Rrnax is a function of the active microorganism concentration in the biofilm and is defined as ... 

The gastrointestinal microflora provide another potential site for drug metabolism within the GIT, and it has received some attention. In normal subjects the stomach and proximal small intestine contain small numbers of microorganisms. Concentrations of these organisms increase toward the distal end of the intestine. A wide variety of aerobic and anaerobic organisms are present in the gut. The microflora, derived primarily... 

Where p = specific growth rate, p max = maximum specific growth rate, X = microorganism concentration, S= growth limiting substrate concentration, and Ks= half saturation coefficient for hydrolysis. 

X2 = aeration basin microorganism concentration - mass/ volume X3 = Secondary Effluent microorganism concentration - mass/ volume Xr = Recycle and Wasted Solids Concentration V2 = Aeration Basin Volume... 

Rate of Bacterial Growth rBH= (iX where X is the microorganism concentration in mass/ volume... 

Supervision and diagnosis. For example, when it is necessary to supervise a microorganism concentration in a biofilm to avoid unstable operating conditions. 

Then, an estimate of the microorganisms concentration can be easily obtained by solving (4) for X that is... 

Advantages of RBCs include the ability to sustain shock loads because of high microorganism concentrations, ease of expansion because of modular design, and low power consumption, which may be particularly attractive for industrial application. Full-scale RBC installations in refineries have performances in removal of oxygen-demanding pollutants comparable to activated sludge systems [5]. 

In order to discuss the practical identifiability of the model studied in Examples 5.1.1 and 5.1.2, Holmberg (ref. 3) computed the sensitivities of the microorganism concentrations y and substrate concentration 2 with... 

Marine microorganism Concentration in seawater (ml-1) Removal (log ) Disinf. needed for inactivation (eq ppm Cl2) Contact time for inactivation (min)... 

An agar plate collects 26 viable colonies over a 24-h period. If the plate diameter is 10 cm and 10-pm-diameter particles are assumed, determine the average microorganism concentration over the 24-h period. 

The S is the input concentration of nutrient (to the leftmost vessel), and D is the washout rate. These two parameters are under the control of the experimenter. The terms 7 and y, are the yield coefficients. For convenience, one can scale substrate concentrations S, by S , time by /D (making m, nondimensional and D = 1), and microorganism concentrations by and to obtain the less cluttered system... 

In most systems the entering microorganism concentration Qo is zko. For a batch system the mass balances develop are as follows ... 

Microorganism concentration in the influent stream to the reactor is zero but is flnite for all required species within the reactor itself. 

Carbon disulfide is widely found in coastal and ocean waters and extensive study has been done to determine levels over the different types of water bodies. The measurements of Carroll (1985) show that the ocean appears to be a source of carbon disulfide, possibly via anaerobic microorganisms. Concentrations of less than 10 nmol/L have been found in a sulfide-rich lake in Spain (Simo et al. 1993). Carbon disulfide has also been detected in the vent fluids and sediment surface waters of undersea hydrothermal sites (Marchand et al. 1994).

In most systems, the entering microorganism concentration, is zero for a flow reactor. 

Chapter 6, by Drever and Vance, provides a useful overview of the distribution and significance of organic acids in soils. Low-molecular-mass acids (e.g., acetic, oxalic, formic) exist in dynamic balance within soils. They are rapidly produced and consumed by microorganisms. Concentrations of...
