Title (EN) METHOD FOR CONTROLLING GROWTH OF MICROORGANISMS AND/OR BIOFILMS IN AN INDUSTRIAL PROCESS
(FR) PROCÉDÉ DE COMMANDE DE CROISSANCE DE MICRO-ORGANISMES ET/OU DE BIOFILMS DANS UN PROCESSUS INDUSTRIEL
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.
(FR) L'invention concerne un procédé de commande d'un biofilm, servant à retirer un biofilm formé et/ou à commander une croissance de micro-organismes, de préférence de bactéries, dans un environnement aqueux d'un processus industriel de fabrication comprenant un matériau fibreux cellulosique. Un composé selon la formule I est administré à l'environnement aqueux du processus, dans laquelle formule I R1, R2 et R3 représentent indépendamment un atome d'hydrogène ; un atome d'halogène ; un groupe hydroxy ; un groupe amino ; un groupe alkylamino, un groupe alkyle, un groupe hydroxyalkyle, un groupe haloalkyle ou un groupe alcoxy possédant 1 à 4 atomes de carbone ; ou un groupe acylamido possédant 1 à 10 atomes de carbone ; et A représente 2-thiazolamine ; 2-propènenitrile ; 2-propénoïque ; un ester d'alkyle ou un ester d'hydroxyalkyle d'acide 2-propénoïque possédant 1 à 4 atomes de carbone ; ou un groupe -CHCHCONR5R6, où R5 et R6 représentent indépendamment un atome d'hydrogène, un alkyle ou un hydroxyalkyle possédant 1 à 4 atomes de carbone, à condition que le composé selon la formule I ne soit pas le 3-[(4-méthylphényl) sulfonyl]-2-propènenitrile ou le 4-amino-N-2-thiazolyl-benzène-sulfonamide.
