PCT No. PCT/SE94/01245 Sec. 371 Date Aug. 8, 1995 Sec. 102(e) Date Aug. 8, 1995 PCT Filed Dec. 22, 1994 PCT Pub. No. WO95/17546 PCT Pub. Date Jun. 29, 1995A method and composition for suppressing or inhibiting the decomposing action of enzymes on hydrogen peroxide, e.g. peroxidase and catalase, during bleaching of cellulose fibres with hydrogen peroxide, especially in connection with the production of recycled paper, in such a way that microorganisms are not markedly affected, and discharges that are dangerous to the environment are minimized. The composition contains hydroxylamine, thiocyanate salts, formic acid, ascorbic acid or nitrites.
