  • Publication number: 20170016179
    Abstract: A biorefining method of processing a lignocellulosic biomass to separate lignin and hemicellulose from cellulose includes the steps of (a) reacting the biomass in an aqueous slurry having a pH less than 7, comprising a transition metal catalyst, hydrogen peroxide; and (b) separating a solid cellulose fraction from dissolved lignin and hemicellulose fractions. The method may also be used to treat cellulose and produce microcrystalline or nanocrystalline cellulose. The transition metal catalyst may be a nanoparticulate catalyst including multivalent iron, iron oxides and iron hydroxides. The nanoparticulate catalyst may be formed by oxidizing a highly reduced solution of iron, such as groundwater that has not been exposed to oxygen.

  • Publication number: 20160355444
    Abstract: A process for producing desired compounds from biomass, including treating a lignocellulosic waste stream in some embodiments. The waste stream is conditioned under acidic or basic conditions, and is then treated in a catalytic reaction step using a transition metal catalyst and an oxidant. The transition metal catalyst can be an iron-based nanoparticulate catalyst. In some embodiments, useful compounds such as lignin, crystalline cellulose and various platform chemicals are produced from the waste stream. In some embodiments, the waste stream is lignocellulosic agricultural or forestry waste. In some embodiments, the waste stream is manure. In some embodiments, desirable bioproducts are obtained from lignocellulosic biomasses using an iron-based nanoparticulate-catalyzed reaction conducted at alkaline pH.

  • Publication number: 20120012065
    Abstract: The present invention provides for a direct correlation between milk production in livestock animals and the presence of alleles of a gene encoding an adipocyte-specific polypeptide, termed leptin, which gene is hereinafter referred to as ob. The invention also provides novel compositions consisting essentially of specific oligonucleotides that are useful as primers to amplify particular regions of the genome during enzymatic nucleic acid amplification, thus providing a rapid, sensitive and specific method for the detection of the ob-gene polymorphism which may be present in a specimen. The invention further provides for methods of screening bovine to determine those having predictably more milk productivity and advantageously selecting those livestock for future breeding and management purposes based on the ob polymorphisms.
