Estimating the term…
A method, device and system for producing preselected products, (either finished products or preselected intermediary products) from biobased precursors or Co2 and/or bicarbonate. The principal features of the present invention include a method wherein a binary culture is incubated with a biobased precursor in a closed system to transform at least a portion of the biobased precursor to a preselected product. The present invention provides a method of cultivation that does not need sparging of a closed bioreactor to remove or add a gaseous byproduct or nutrient from a liquid medium. This improvement leads to significant savings in energy consumption and allows for the design of photobioreactors of any desired shape. The present invention also allows for the use of a variety of types of waste materials to be used as the organic starting material.
A method for producing preselected products from biobased precursors said method characterized by incubating a binary culture with said biobased precursor in a closed system to transform at least a portion of said biobased precursor to a preselected product.
A closed bioprocessing system characterized by the presence of a binary culture comprising at least one photoautotroph culture and at least one heterotroph culture.
A non-aerated photobioreactor for obtaining biotechnology products using CO2 and light together with a binary culture made up of a combination of a phototrophic organism and a heterotrophic organism said photobioreactor having a chamber with a height to diameter ration greater than two and lit by an artificial lighting system comprised of light emitting diodes (LEDs) arranged in a spaced configuration.
