Appl. No.:

12/676622

Inventors:

Joshua Trueheart - Concord MA, US
Jefferson Clay Lievense - Kensington CA, US
Sara Iverson - Lexington MA, US

International Classification:

G01N 21/64

US Classification:

435 29, 4352541, 4352521

Abstract:

The present disclosure provides technologies for identifying, characterizing and/or sorting pellet-forming microorganisms such as bacteria and/or fungi (e.g., yeast) in liquid culture, and particularly under fermentation conditions. In some embodiments, the pellet-forming microorganisms produce one or more commercial products. For example, in some embodiments the pellet-forming microorganisms produce one or more organic acids, carotenoid compounds, essential fatty acids, industrial enzymes, active pharmaceuticals, extracellular carbohydrates, and insecticidal compounds, etc. In many embodiments, the organisms are sorted while in their pellet form.

US Classification:

435200

Abstract:

The present invention discloses enzymes having xylanase activity. The xylanases are characterized in that they are active at a temperature of 80. degree. C. or higher. The enzymes are obtainable from anaerobic thermophilic bacteria. The enzymes are suited for use in paper and pulp production processes. The invention also describes cloning and expression of genes having xylanase activity obtained from the deposited strains.
