  • Patent number: 8409853
    Abstract: A method and system for the enzymatic treatment of a lipid containing feedstock comprises contacting the feedstock with a processing aid, then causing the feedstock to pass at a substantially constant flow rate through a treatment system comprising a plurality of enzyme-containing fixed bed reactors connected to one another in series. The fixed bed reactors can be individually serviceable, the flow rate of the feedstock remaining substantially constant through the system when one of the fixed bed reactors is taken offline for servicing. In the most preferred embodiment, the processing aid is a substantially moisture-free silica. The processing aid can be placed in one or more of the fixed bed reactors, disposed above the enzyme in the reactor, or it can be in a pre-treatment system which can comprise one or more reactors.

    Abstract: The invention provides a use of platelet activating factor acetylhydrolase (PAF-AH) activity as a biomarker for severe or fatal anaphylaxis in a subject. The level of PAF-AH activity inversely correlates with the susceptibility to severe or fatal anaphylaxis. The use comprises assaying PAF-AH activity in a sample from the subject and comparing the measured activity to a reference value, wherein a lower level of measured PAF-AH activity relative to said reference level of PAF-AH activity indicates a presence of or susceptibility to severe or fatal anaphylaxis in the subject. A method for treating or preventing severe or fatal anaphylaxis in a subject is also provided. The method comprises increasing serum platelet activating factor acetylhydrolase (PAF-AH) concentration in the subject by administering to the subject, PAF-AH and/or a PAF receptor antagonist. A composition for treating severe or fatal anaphylaxis is also provided.

  • Publication number: 20120190072
    Abstract: The present invention relates to a method for preparing a variant lipolytic enzyme comprising expressing in a host organism a nucleotide sequence which has at least 90% identity with a nucleotide sequence encoding a fungal lipolytic enzyme and comprises at least one modification at a position which corresponds in the encoded amino acid sequence to a) the introduction of at least one glycosylation site in the amino acid sequence compared with the original fungal lipolytic enzyme; b) the introduction of at least one amino acid at a surface position and at a location in an external loop distal to the active site of the enzyme which is more hydrophilic; or c) a substitution or insertion at one or more of positions disclosed herein or a deletion at one or more positions disclosed herein. The invention also relates to polypeptide produced by the method and to novel nucleic acids.

  • Patent number: 8206963
    Abstract: An acetyl xylan esterase variant having perhydrolytic activity is provided for producing peroxycarboxylic acids from carboxylic acid esters and a source of peroxygen. More specifically, a Thermotoga maritima acetyl xylan esterase gene was modified using error-prone PCR and site-directed mutagenesis to create an enzyme catalyst characterized by an increase in the ratio of peracetic acid formation to peracetic acid hydrolysis specific activities (PAAF/PAAH ratio). The variant acetyl xylan esterase may be used to produce peroxycarboxylic acids suitable for use in a variety of applications such as cleaning, disinfecting, sanitizing, bleaching, wood pulp processing, and paper pulp processing applications.
