The present invention provides a method of producing a photosynthetic product, the method comprising maintaining a photosynthetic plant or algal cell suspension culture, in the presence of water, light and a carbonic acid-enriched growth medium. The carbonic acid may, for example be provided by feeding the photosynthetic plant cell suspension culture with a carbonic acid solution, a solid or liquid precursor thereof, or a gaseous mixture of carbon dioxide and one or more other gases. The invention also provides a method for producing a photosynthetic product, the method comprising maintaining a photosynthetic plant or algal cell suspension culture, in the presence of water, light and a carbon source selected from carbon dioxide and carbonic acid, wherein the culture is maintained at a pH of less than 7.0, preferably 4.5 to 5.5.

One or more systems for automated preparation of a regenerative epidermal suspension comprises a base unit, a cartridge assembly containing a cup, and a tissue disaggregator. The system may also include related tools. The system executes one or more sequences wherein a first motor actuates the pestle against a tissue sample that is disposed along a screen within the cup while the tissue sample is in contact with, in sequence, an enzyme solution, a first buffer solution, and then a second buffer solution. To transition between fluidic contact stages or steps, the tissue disaggregator engages with and lifts the cup into a raised position within a processing area of the cartridge while a base plate motor rotates the appropriate well into alignment under the cup for each processing step. Once the sequence is complete, a user may draw up a regenerative epidermal suspension through an opening in the cartridge top cover.

This invention relates to a substrate for mammalian cell culture comprising a co-polymer hydrogel comprising monomeric units of acrylamide, bisacrylamide and a coupling compound, such as 6-acylamidohexanoic acid (6AHA). A cell adhesion molecule, such as a component of the extracellular matrix (ECM), is covalently coupled to the coupling compound monomeric units of the co-polymer. The stiffness and cell adhesion molecule density of the substrate can be independently controlled by altering the concentration of acrylamide and coupling compound in the hydrogel, respectively. Substrates and methods and kits for their production are provided, along with cell culture systems and methods of culturing mammalian cells.
