Specific respiration rate

A plot of the specific respiration rate ( 02 versus the specific growth rate coefficient [L is linear, with the intercept on the ordinate equal to the oxygen uptake rate for cell maintenance. A formulation of this is ...

Hence, from Eqs. (Ill) and (112), we find that the specific respiration rate should be a linear function of 1/0 ... 

The metabolic quotient, or specific respiration rate (qCO-, is the ratio of the basal respiration rate (as CO2-C) per unit MBC, and provides an indication of efficiency of microbial in utilization of available substrates (Anderson and Domsch, 1993). Low C02 in detritus of the impacted site suggests poor efficiency of microbes in utilization of available substrates (DeBusk and Reddy, 1998 Wright and Reddy, 2001b). Minimal differences in qC02 were observed for 0-10 cm soil of impacted and reference sites. Consumption of electron acceptors such as oxygen, nitrate, and sulfate during... 

Kobayashi. et al. (1973 b) studied three cases (1) uniform respiration activity throughout mycelial pellets. (2) respiration activity as a function of age distribution within the pellet. (3) respirative activity adaptation to the local oxygen concentration within the pellet. In case 1. it was found that the effectiveness factor (Ej) is equal to the ratio of the specific respiration rate of a pellet to the respiration rate of well dispersed filamentous mycelia. The theoretical and experimental results for each case are given in Figure 4. It is seen that the three cases considered gave similar results and it is difficult to discriminate between them with the limited experimental data available.
