  • PROCESS FOR SEPARATING BIOMASS COMPONENTS
    Publication number: 20150025229
    Abstract: The present invention provides a process and System for Separation of biomass components into individual components such as cellulose, hemicellulose and lignin. The present invention provides a process for separating lignin in its native form. The cellulose obtained by the process of the present invention is highly reactive for saccharification.

  • Synthesis of 2?,3?— and 3?,5?—cyclic phosphate mono-and oligonucleotides
    Patent number: 8618279
    Abstract: The invention provides a novel method for the chemical synthesis of 2?,3?-cyclic phosphate and phosphorothioate of mono and terminated oligonucleotides synthesis. The invention also provides a novel method of for the chemical synthesis of 2?,3?- and 3?,5?-cyclic phosphate and phosphorothioate mononucleotide nucleotides. The process is based on quick and efficient cyclization of phosphoramidate moiety and neighboring hydroxyl group. The present invention is directed towards the synthesis of high purity DNA and RNAs, specifically to introduce cyclic phosphate at 3?-end of oligonucleotides. Such DNA and RNA's have extensive application in therapeutics, diagnostics, drug design, and selective inhibition of an RNA sequence within cellular environment, in pre-tRNA cleavage and in ribozyme ligation. The 2?,3?-cyclic phosphate nucleosides are involved in a vast number of applications in molecular biology in general and mammalian cells in particular.

  • SINGLE STEP PROCESS FOR SEPARATING BIOMASS COMPONENTS
    Publication number: 20100190973
    Abstract: The invention is directed towards a method of pretreatment of a lignocellulose containing biomass so as to make the biomass amenable to enzymatic digestion. More particularly, the instant application discloses a single step separation of biomass into individual components such as cellulose, hemicellulose and lignin without losing chemical nature and with high purity at a time.
