I am wanting to sparge tube cultures of a bacterial culture to promote gas transfer and provide some mixing in tube cultures. Can anyone recommend an optimal choice between: A (145-174 micron), B (70-100 micron), C (25-50 micron), D (10-20 micron), or E (4-8 micron)
Of course smaller porosity should lead to better mass transfer but other problems such as fouling and excessive back pressure may be a problem at low sizes.
Many Thanks, Chris
