There are 4 breeds of dogs available at a pet store. If the ratio of those dogs available is 3 : 7 : 1 : 23, find the total number of dogs available. It is known that the minimum number of dogs of any breed available is 19.
In a well aerated and agitated microbial culture, the 'supply' of oxygen is equal to 'demand' (uptake) of the growing culture. The KLa for such a system will be (KLa = volumetric mass transfer coefficient, C* = dissolved oxygen concentration in liquid in equilibrium with gaseous oxygen, C = instantaneous value of dissolved oxygen concentration, 'r' = specific oxygen uptake rate per unit weight of cells, X = dry weight of the cells per unit volume)
