ABSTRACT:
A method and bioreactor (10) apparatus is described for maintaining cells in a culture medium containing gas or liquid aphrons. A preferred microbubble generator (42, 42A) of a gas which is necessary for maintaining the cells to produce plant derived chemicals is described. Bioparticles (11) containing magnetically susceptible particles are provided in a column (12) surrounded by a solenoids (13, 14, 14A) which act to hold the bioparticles in position in the column. Preferably, one of the solenoids with a magnetically susceptible screen (24) acts as a valve to allow a portion of the bioparticles to be removed from the column.
