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 considerable activity at a pH of 9. 0 and a temperature of 70. degree. C. The enzymes are obtainable from deposited strains which are related to alkaliphilic Bacilli. The enzymes are suited for use in paper and pulp production processes.

International Classification:
C12N 114
US Classification:
4352533
Abstract:
The bacteria Pseudomonas fluorescens, Pantoea (Enterobacter) agglomerans, Bacillus cereus, and Xanthomonas campestris are useful in reducing the pitch content of pulps and pulpwoods used in making cellulosic products. Such bacteria are also useful in reducing the color staining by staining fungi of structural wood by inoculating the structural wood or log sources from which it is to be cut.

US Classification:
435278
Abstract:
The present invention relates to the use of certain fungi in the reduction of the pitch and/or lignin content of cellulosic materials. In particular, the white rot fungi Schizophyllum commune, Trichaptum biforme and Phanerochaete gigantea are useful in reducing pitch and/or lignin, or both, which saves electrical energy during the mechanical refining of pulps and pulpwoods used in making cellulosic products.

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.
