  • Patent number: 10865190
    Abstract: A process for producing furan dicarboxylic acid or an ester thereof from a feedstock comprising hydroxymethyl furfural (HMF) and humins is disclosed. Humins are a byproduct from reactions forming HMF from sugars and are typically removed from the HMF prior to any further processing. A humins-containing HMF feedstock is utilized to produce furan dicarboxylic acids and ester substantially free from humins.

  • Patent number: 10731225
    Abstract: This invention relates to polynucleotide sequences encoding genes that can confer resistance to the plant pathogen Colletotrichum, which causes anthracnose stalk rot, leaf blight and top dieback in corn and other cereals. It further relates to plants and seeds of plants carrying chimeric genes comprising said polynucleotide sequences, which enhance or confer resistance to the plant pathogen Colletotrichum, and processes of making said plants and seeds. The invention further presents sequences that can be used as molecular markers that in turn can be used to identify the region of interest in corn lines resulting from new crosses and to quickly and efficiently introgress the genes from corn lines carrying said genes into other corn lines that do not carry said genes, in order to make them resistant to Colletotrichum and resistant to stalk rot.
