Abstract
The invention relates to a method of improving the transfer in an annular biological reaction chamber defined by coaxial inner and outer walls (11, 12) and in which there flows a liquid reaction medium containing a culture of microorganisms or of cells from vegetable or animal macroorganisms in suspension. At least one of the walls is an exchange wall enabling gaseous or liquid matter to be transferred or allowing light to pass through. The reaction medium is subjected to a turbulent primary flow that is helical and that under the action of centrifugal force creates rotary secondary vortices so as to encourage renewal of the culture in the vicinity of the exchange wall.
