Which of the following does not require the measurement of DO concentration?
Which of the following is not a surface active contaminant?
Who described the static method of gassing-out?
Which of the following was used to gas out oxygen in the dynamic method of gassing-out?
Who described the dynamic method of gassing out?
Which of the following is not a measuring parameter in oxygen-balance technique?
Who claimed that oxygen balance technique is suitable for only small-scale fermenters?
The unit of KLa is
cm^2
h^(-1)
cm^3
cm h^(-1)
Which of the following is the method of determinating KLa values?
Oxygen-balance technique
Sulphite oxidation technique
Static method of gassing out
Dynamic method of gassing in
The rate of oxygen transfer is described by the equation
dC{L}/dt = KLa (C* – C{L})
dC{L}/dt = KLa (C*)
dC{L}/dn = KLa (CL)
dC{L}/dn = KLa (C* – C{L})
The value C{rit} is an efficient value for oxygen concentration. True or false?
True
False
The oxygen balance technique is used for gas-gas transfer. True or false?
True
False
