METHOD FOR CONTROLLING GROWTH OF MICROORGANISMS AND/OR BIOFILMS IN AN INDUSTRIAL PROCESS

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-benzenesulphonamide.
