  • Patent number: 8679814
    Abstract: A method of preparing a cold adapted xylanase by use of recombinant DNA techniques. A nucleic acid and corresponding amino acid sequences of a cold adapted xylanase, isolated from antarctic marine origin, preferably from an Antarctic bacteria (Psychrobacter sp.) are provided. These can be used in a variety of industrial contexts and for a variety of commercial purposes including more complete hydrolysis of lignocellulosic biomass into simple sugars that can then be fermented to products, such as liquid fuels and chemical feedstocks. The enzymes are also useful in the production methods of other industries, such as the animal feed, baking, and paper industries.

  • Patent number: 8337829
    Abstract: The subject invention pertains to tumor cell lines useful for increasing the proliferation potential of any human or animal cell in culture, thereby providing immortalized or continuous cell lines and cultures. The invention also concerns proliferation factors, and compositions containing the factors, which are capable of increasing the proliferation potential of any human or other animal cell in culture. The subject invention further pertains to a method for proliferating cells in culture by contacting cells with the proliferation factors. The proliferated cells can range in plasticity and can include, for example, blast cells, fertilized ova, non-fertilized gametes, embryonic stem cells, adult stem cells, precursor or progenitor cells, and highly specialized cells. Optionally, the cells can be induced to cease proliferation.
