  • Publication number: 20170016007
    Abstract: One or more genes in a biosynthesis pathway for a vitamin or other essential nutrient which is needed for the survival of a microorganism can be used as an effective selective marker to identify cells transformed with an exogenous nucleic acid.

  • Publication number: 20160115505
    Abstract: Multi-stage, biological processes and systems for converting a C1 carbon source to desired end products are described. The processes comprise dividing a gaseous C1-containing substrate, in parallel, among multiple bioreactor stages. Liquid products are successively fed, in series, from a first bioreactor stage to downstream bioreactor stages. Operation can be simplified by avoiding the requirement for microorganism separation and recycle at each stage. In addition, overall vapor-liquid mass transfer for the combined stages is very favorable, leading to high end product productivity with comparably low byproduct metabolite productivity.

  • Patent number: 9315830
    Abstract: The invention provides a genetic tool to insert, replace, delete, or otherwise manipulate a nucleic acid sequence in a microorganism to produce a recombinant microorganism. Notably, the invention makes use of homologous recombination, a type of genetic recombination in which nucleotide sequences are exchanged between two similar or identical molecules of DNA. Since the invention involves three homologous recombination events, it is referred to as a “triple cross” method.
