  • Patent number: 8664373
    Abstract: The present invention provides a low-cost, efficient method for producing a glycolipid biosurfactant, in particular, lactonic sophorose lipids. This method is characterized by culturing a microorganism capable of producing the biosurfactant under limited oxygen supply. The present invention enables preferential production of lactonic sophorose lipids and facilitates recovery of the lactonic sophorose lipids in a solid form. Further, the present invention enables production of high purity acidic sophorose lipids by hydrolyzing high purity lactonic sophorose lipids produced by the above method. The present invention also provides lactonic sophorose lipids that possess strong antibacterial and antifungal activities, and an antibacterial and/or antifungal agent containing the sophorose lipids.

  • Patent number: 8653255
    Abstract: Derivatives are synthesized of starting materials, usually polysaccharides, having sialic acid at the reducing terminal end, in which the reducing terminal unit is transformed into an aldehyde group. Where the polysaccharide has a sialic acid unit at the non-reducing end it may be passivated, for instance by converting into hydroxyl-substituted moiety. The derivatives may be reacted with substrates, for instance containing amine or hydrazine groups, to form non-cross-linked polysialylated compounds. The substrates may, for instance, be therapeutically useful drugs peptides or proteins or drug delivery systems.

  • Patent number: 8648187
    Abstract: The invention provides systems, methods and kits for the separation and/or purification of double-stranded and single-stranded nucleic acids from the same sample. The method includes first mixing a sample containing both double-stranded nucleic acid and single-stranded nucleic acid with a solution including a chaotropic salt and a non-ionic detergent to generate a mixture; then applying the mixture to a first mineral support for double-stranded nucleic acid to bind; and collecting the flow-through which contains unbound single-stranded nucleic acid. The method further includes diluting the non-ionic detergent of the flow-through, and applying the diluted flow-through to a second mineral support for the single-stranded nucleic acid to bind. Alternatively the flow-through can be mixed with a lower aliphatic alcohol prior to loading of the second column. The double-stranded and the single-stranded nucleic acids can be eluted from the mineral supports respectively.
