Claim 20:
21. A method for forming a bioreactor product, the method comprising:
providing a bioreactor according to claim 14, wherein:
the bioreactor insert apparatus further comprises biofilms adhered to the biofilm supports, the biofilms having biological activity,
an aqueous reaction medium at least partially fills the interior reaction volume and the bioreactor insert apparatus, and
suspended microorganisms are present in the aqueous reaction medium;

feeding an influent stream comprising one or more reactants for conversion to the bioreactor insert apparatus via the first fluid inlet;
circulating the influent stream through the inlet volume, into the exit volumes, through the exit biofilm supports and biofilms thereon, into the external volume, through the recirculation biofilm supports and biofilms thereon, into the recirculation volumes, into the outlet volume, and through the first fluid outlet; and
converting the one or more influent reactants to a product.
