According to exemplary embodiments, provided herein are methods for nutrient fortification, including determining a nutrient profile for a first food product, modeling a micronutrient profile based on the nutrient profile, culturing yeast in the micronutrient profile and applying the cultured yeast to a second food product.

A system includes a photobioreactor that provides a channel configured to contain an algae slurry, a duct positioned adjacent the channel and configured to convey a gas, and a barrier separating the duct from the channel and providing one or more apertures to allow a portion of the gas to be injected into the algae slurry from the duct.

The invention relates to a device for incubating cultures, comprising a culture chamber storing the cultures, the cultures being fumigated with an incubation gas. The invention is characterized in that the incubation gas source is used when incubating the cultures with the incubation gas source which is free of liquid incubation gas.

In a first aspect of the present invention, a manipulation method of an organism is provided, comprising: forming an air bubble by introducing gas into liquid in which an organism is submerged; controlling of energy before, during or after the forming of the air bubble, including controlling of difference (E1 - E2) obtained by subtracting, from surface free energy E1 at an interface between the gas and the organism, surface free energy E2 at an interface between the gas and the liquid; and manipulating the organism using the air bubble, by bringing the air bubble into contact with the organism during or after the controlling of energy.

A culturing device is equipped with an accommodation unit, and a convection generating unit provided in the accommodation unit. In the accommodation unit, microalgae are cultured while the convection generating unit generates convection in the culturing solution in the accommodation unit. During the culturing, a portion of the culturing solution is drawn in through collection pipes by the pump. Thereafter, the culturing solution that was drawn in is discharged from the collection pipes into the culturing solution inside the accommodation unit.

Miniature stirred tank bioreactor and system; the bioreactor configured for single use culturing providing unobstructed culturing volume with sensors, probes and ports using minimally invasive placement in-wall or across the wall methods; the bioreactor further capable of containing scaffolds and features for culturing cells and tissue, including structures providing surfaces for cell growth, and screens for retaining microparticles during media exchange.

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

A cell culturing system includes a reactor, a flow channel that allows a culture medium to flow into and out of the reactor, a waste liquid channel that discharges the culture medium from the flow channel, and a waste liquid container capable of storing the culture medium passing through the waste liquid channel. The waste liquid channel includes a temporary storage unit capable of temporarily storing the culture medium. The waste liquid container is located below the temporary storage unit) in a gravity direction, and the temporary storage unit is provided above the flow channel in the gravity direction. The temporary storage unit temporarily stores the culture medium discharged from the flow channel and allows the culture medium to flow out toward the waste liquid container.

The invention relates to a method for recovering a biocatalytically produced organic substance from a reaction mixture, comprising—providing a reaction mixture, wherein the organic substance is produced using a biocatalyst, which reaction mixture comprises a substrate for the biocatalyst in a continuous aqueous phase, and wherein further a product recovery phase is present into which the organic substance migrates or onto which the organic substance absorbs or adsorbs; and—separating the product recovery phase comprising the produced substance from the aqueous phase and the biocatalyst. The invention further relates to a bioreactor system for biocatalytically producing a substance, comprising an apparatus, said apparatus comprising a reaction compartment (11) situated in a lower part of the apparatus and a separator compartment (9).

The present invention concerns an improved bioreactor with enhanced oxygen transfer. In lieu of the standard impeller and sparger assembly, a rotating gas sparger is used to introduce oxygen into the reactor. A mechanical drive shaft is coupled to a conduit from which a length of tubing extends. A source of pressurized gas is fluidly coupled to the tubing, which tubing is rotated via the mechanical drive shaft. The rotating tubing has a variably sized outlet for introducing oxygen bubbles into the liquid medium of the reactor, the bubbles providing both mechanical agitation and oxygen transfer due to the rotation of the tubing.
