  • Patent number: 11078507
    Abstract: The present invention pertains to an in vitro method in which the frequency of the targeted nucleotide sequence containing the DNA fragment of interest is increased stepwise, by several rounds of 1) dilution of a sample containing the DNA fragment of interest into several replicates (separation), 2) randomly amplifying DNA in the replicates (concentration), 3) detecting the DNA fragment of interest in at least one of the diluted and amplified replicates (selection) and repeating steps 1) through 3) until the DNA fragment of interest can be sequenced by standard sequencing techniques.

  • Publication number: 20150197774
    Abstract: Lignocellulosic biomass is pre-treated to provide crude monosaccharides and crude polysaccharides, which are then hydrolysed in the presence of at least one enzyme to provide crude monosaccharides. These are continuously provided in an aqueous fermentation broth at a concentration such as 100 g/L along with associated inhibitory factors to a fermentation vessel containing suspended thermophilic microorganisms, and then continuously fermented at elevated temperature by said microorganisms to form ethanol. At least a portion of said ethanol is continually removed from the fermentation broth to permit the fermentation to continue despite the introduction of the inhibitory factors.
