The system can include multiple harvesters disposed at least in part vertically above the receptacles and configured to simultaneously harvest the biomass from the receptacles. Each of the harvesters can include: multiple harvesting baskets configured to be lowered from above the receptacles and into each of the receptacles; multiple sensors disposed to sense growth conditions within the harvesting baskets; and a controller configured to communicate with each sensor of the multiple sensors, and based on data received from the sensors, configured to control harvesting patterns of each harvester to enhance biomass material growth within the receptacles.

A bioreactor including a containment structure containing a liquid culture medium for cultivating seaweed. The containment structure includes a sidewall extending vertically between a top and bottom section where the bottom section has an effluent arranged to allow extraction of cultivated seaweed. A spiral liner is positioned adjacent to an inside surface of the sidewall. The recirculator includes a pump arranged to continuously receive a portion of the liquid culture medium via an inlet from the bottom section and output the liquid culture medium via the outlet at the top section. Sensors monitor environmental conditions within the bioreactor. Light emitters are arranged along a surface of the spiral liner. Flow generators, positioned within the containment structure in a spiral configuration between the top section and bottom section, are configured to direct a flow of the liquid culture medium from the top section toward the bottom section of the containment structure.

Reactors, systems and processes for the production of biomass by culturing microorganisms in aqueous liquid culture medium circulating inner loop reactor which utilize nonvertical pressure reduction zones are described. Recovery and processing of the culture microorganisms to obtain products, such as proteins or hydrocarbons is described.

The present invention relates to a large-scale photosynthetic bioreactor in which transparent photobioreactors including a baffle are connected in parallel or in series by an adhesive element so that the reactor volume can be easily scaled up for scale-up culture of photosynthetic organisms, and to a fabrication method thereof. The large-scale photosynthetic bioreactor according to the present invention makes it possible to culture a larger amount of microalgae than a conventional photobioreactor in the same area. In addition, it has high light transmittance, produces a large amount of biomass per unit area due to smooth mixing, and has a significant effect of reducing carbon dioxide. Furthermore, the present invention has an advantage in that the number of photosynthetic bioreactors required to culture the same scale of photosynthetic organisms is significantly smaller than that in a conventional process for culture of photosynthetic organisms, and thus the operating costs can be reduced.
