A polymer detection probe is provided that includes a binding module that specifically binds to at least one polymer and a reporter module that is spectroscopically detectable. The binding module can be a carbohydrate-binding module (CBM). The reporter module can be a fluorescent protein. A complex is provided that includes a probe specifically bound to a pulp or paper product including at least one surface available lignocellulosic polymer. A pulp or paper product is provided that includes at least one surface available lignocellulosic polymer and at least one probe bound thereto. Methods are provided that employ a lignocellulosic probe. A method of detecting a lignocellulosic polymer or other type of polymer is provided. A method of determining the effectiveness of an industrial treatment on pulp or a paper product is also provided. A method of determining a physical property of pulp or a paper product is further provided.

Polymer probes and methods

A method is provided for controlling organic contaminants, such as xylans, pitch or both, that interfere with bleaching of fibers and/or cause other interference(s) in papermaking systems. The method includes contacting fibers before any bleaching thereof with a composition which contains a hemicellulolytic enzyme and an organic contaminant removal adjuvant to liberate the organic contaminants from the fibers. The treated fibers can then be bleached and further used, for example, in making paper. The present invention also relates to the treatment compositions and to paper products made with fiber materials treated with these compositions. A method of enhancing enzymatic degradation of a substrate as well as formulations and systems for achieving the same are also provided. Various substrates can be degraded or otherwise processed, including biomass, paper mill sludge, and animal hides. Enzymatic degradation can be enhanced by including one or more polymeric surfactants.
