Abstract: The invention is directed to a method for the production of biomass comprising the steps of (i) capturing CO2 from a CO2 containing gas stream, and subsequently reducing the captured CO2 to a reduced CO2 product; and (ii) an anaerobic fermentation, wherein a carbon substrate is used for the production of an organic feedstock; and (iii) an aerobic fermentation, wherein the organic feedstock is used for the production of biomass; wherein the reduced CO2 product is fed to the anaerobic fermentation and/or to the aerobic fermentation and the co-produced oxygen is fed to the aerobic fermentation.

Abstract: The present invention relates to a method for cultivating a microorganism capable of utilizing an organic feedstock, comprising the steps of: (i) cultivating the microorganism in one or more bioreactors (1); (ii) capturing CO2 from the one or more bioreactors (1) and reducing the CO2 to an organic feedstock in a reduction unit (3); and (iii) feeding at least a part of the organic feedstock from the reduction unit (3) into one or more bioreactors (1).

Abstract: The present invention describes the transformation of a microorganism that does not naturally produce a ?-lactam compound with polynucleotides involved in the biosynthesis of ?-lactam compounds and the use of such transformed microorganisms in the production of ?-lactam compounds or in the identification of genes or factors involved in the synthesis of a ?-lactam compound.

Abstract: A method and apparatus for effectively aerating large-scale cultures of microorganisms is disclosed.

Abstract: The present invention describes a method of culturing a micro-organism under aerobic conditions in a fermentation vessel comprising the injection of a first oxygen-containing gas into the lower portion of the vessel in a heterogeneous flow causing a chaotic motion of the broth and the introduction of a second oxygen-containing gas in the vessel characterised by introducing the second oxygen-containing gas as a heterogeneous flow of gas bubbles moving in the vessel in all possible directions, independent of the direction of the flow of the broth resulting in turbulent flow conditions at the site of injection; and as a set of gas bubbles of non-uniform size and a wide size distribution.
