A method for cell culturing using the bioreactor, more specifically a method for the expansion and differentiation of organoids using the bioreactor.

Contiguous flow anaerobic digester for mechanization of organic matter and production of fertilizer powering the conditions and performance of the anaerobic digestion process, through homogenization of the sludge and process temperature, wherein the digester is tubular shaped and comprises a biogas exhaust valve at the top of the digester. One end of the digester has a sludge outlet connection, a water- and gas-tight zipper that is resistant to the corrosive elements of digestion, and an outlet. The opposite end of the digester has a mud inlet, and a water- and gas-tight zipper that is resistant to the corrosive elements of digestion, wherein said digester further comprises at its base a gas irrigation system for biogas recirculation composed of a polymeric material resilient to the corrosive elements of anaerobic digestion.

There is provided a process for effecting growth of phototrophic biomass within the reaction zone of a photobioreactor, comprising, after effecting at least a reduction in the molar rate of supply of carbon dioxide to the reaction zone of the photobioreactor, supplying a gaseous photobioreactor exhaust, that includes diatomic (or molecular) oxygen being generated by photosynthesis effected within the reaction zone by the supplied carbon dioxide, to a combustion zone of a combustor.

The present invention concerns the field of high-efficiency, quality-controlled production of blue-green algae for direct human consumption, for extraction of proteins, vitamins, and amino acids, and for production of organic materials loaded with the special isotope 13C. It is an object of the present invention to describe a high-efficiency photobioreactor.
