Title
(EN) METHOD FOR CONTROLLING GROWTH OF MICROORGANISMS AND/OR BIOFILMS IN AN INDUSTRIAL PROCESS
Abstract
(EN)
The invention relates to a method for controlling of a biofilm, for removing of a formed biofilm and/or for controlling a growth of microorganisms, preferably bacteria, in an aqueous environment of an industrial manufacturing processcomprising cellulosic fibre material.A compound according to Formula I is administered to the aqueous environment of the process, in which Formula I R1, R2 and R3 independently represent a hydrogen atom; halogen atom;hydroxy group; amino group; alkylamino group,alkyl group,hydroxyalkyl group, haloalkyl group or alkoxy group having 1 to 4 carbon atoms; or an acylamido group having 1 to 10 carbon atoms; and A represents 2-thiazolamine; 2-propenenitrile; 2-propenoic acid; alkyl ester or hydroxyalkyl ester of 2-propenoic acid having 1 to 4 carbon atoms; or -CHCHCONR5R6 group, where R5 and R6 represent independently hydrogen atom, alkyl or hydroxyalkyl having 1 to 4 carbon atoms, with the proviso that the compound according to Formula I is not 3-[(4-methylphenyl)sulphonyl]-2-propenenitrile or 4-amino-N-2-thiazolyl-benzene-sulphonamide.
