DECOMPOSITION AND REMOVAL OF HYDROPHOBIC COMPONENT OF WOOD BY MICROORGANISM, PRODUCTION OF MODIFIED MECHANICAL PULP BY MICROORGANISM AND MODIFIED MECHANICAL PULP OBTAINED BY THE SAME METHOD

摘要

PROBLEM TO BE SOLVED: To obtain a mechanical pulp providing paper excellent in characteristics of quality of paper such as paper strength, by treating a papermaking raw material and/or white paper with a specific bacterium belonging to the genus Pseudomonas to prevent a pitch trouble. ;SOLUTION: A papermaking raw material and/or white paper is treated with a bacterium belonging to the genus Pseudomonas capable of decomposing resin acids, fatty acid glycerides and fatty acids [especially preferably Pseudomonas resinovorans ATCC-14,235]. The resin acids, the fatty acid glycerides and the fatty acids among hydrophobic components of wood can be decomposed and removed by the mild treatment.;COPYRIGHT: (C)1997,JPO
