Bacterial Physiology

In the idealized framework outlined above, bacterial physiology is represented by two parameters only. The yield coefficient YBc gives the stoichiometric link between consumption of organic carbon and the limiting mineral nutrient, whereas the specific affinity constant aB defines the volume of water cleared for limiting mineral nutrient per unit bacterial biomass, per unit time. 

In a model where biomass is defined as the cell content of the limiting element, uptake = growth (disregarding possible complications due to leak- 

An interesting aspect of Eq. (8) was discussed by Jumars et al. (1993). The only factor directly influenced by temperature is the diffusion constant D, which is a function of water viscosity. The temperature dependence of this physical process is less than the Q10 of 2.7-3 normally found for biological processes. In our expression for BCD [Eq. (2)], however, such an argument would apply to both aB in the numerator and aA in the denominator the effect on affinity constants would therefore be expected to cancel out. From the preceding arguments, clearance rates and affinity constants

These corrected values for the pKA of HNO (>11) and reduction potential of NO (< —0.7 V) demonstrate that HNO, rather than NO, is the predominant species in neutral solution and indicate that NO cannot be easily converted to NO- by simple outer-sphere electron transfer (Scheme 6), unlike the O2/O2 redox couple. The different potentials and concentrations of NO and O2 in cellular or physiological systems suggest that NO is essentially inert to reduction to NO in mammalian biology. Note that certain processes in bacteria are suggested to have sufficient potentials to reduce NO (165, 166), which may have some importance both to normal bacterial physiology, including nitrification and denitrification, and to antibacterial and pathogenic responses.

A second P-substituted polyester poly-P-hydroxy pentanoate (PHP) has been extracted from sewage (43). The polyester is probably similar to PHB with respect to bacterial physiology. However the polymer has its own characteristic melting point and crystalline structure (44).
