Abstract
The present invention relates to the use of compounds of formula (I) in the treatment of products, in particular of aqueous or nonaqueous compositions, preferably water and aqueous compositions, against bacteria of the Burkholderia cepacia complex (Bcc), and also the use thereof in a process for treating an aqueous composition or water with respect to strains of the Bcc complex. formula (I) wherein: R2 represents a hydrogen atom or a methyl or ethyl radical; R3 represents a linear C1-C12 alkyl radical (saturated), optionally substituted with a hydroxyl group; or a linear C2-C12 alkenyl radical (C═C unsaturated), optionally substituted with a hydroxyl group.
Claims20
A process for treating a product that may be contaminated by bacteria of the Burkholderia cepacia complex (Bcc) which comprises contacting the product with an amount effective for protecting the product against bacteria of the Burkholderia cepacia complex of at least one compound of formula (I), an organic or mineral acid or base salt thereof, a solvate thereof or a mixture thereof:
- formula (I) wherein:
- R2 represents a hydrogen atom or a methyl or ethyl radical;
- R3 represents a linear C1-C12 alkyl radical (saturated), optionally substituted with a hydroxyl group;
- or a linear C2-C12 alkenyl radical (C═C unsaturated), optionally substituted with a hydroxyl group,
- thereby protecting the product against bacteria of the Burkholderia cepacia complex (Bcc).
A process for treating a product selected from the group of water or an aqueous composition i) to prevent the contamination of said product by one or more microorganisms including bacteria of the Burkholderia cepacia complex, ii) or to treat said product that is contaminated by one or more microorganisms including bacteria of the Bcc complex, comprising at least one step of bringing a sample of the product to be treated or of a stream of water to be treated into contact with an amount effective for treating the product against bacteria of the Burkholderia cepacia complex of at least one compound of formula (I),
- an organic or mineral acid or base salt thereof, a solvate thereof or a mixture thereof:
- formula (I) wherein:
- R2 represents a hydrogen atom or a methyl or ethyl radical;
- R3 represents a linear C1-C12 alkyl radical (saturated), optionally substituted with a hydroxyl group;
- or a linear C2-C12 alkenyl radical (C═C unsaturated), optionally substituted with a hydroxyl group.
A process for preserving a product that may be contaminated by bacteria of the Burkholderia cepacia complex, comprising a step of incorporating into said product, during the production thereof, or after the production thereof, and before storage, one or more compounds of formula (I),
- an organic or mineral acid or base salt thereof, a solvate thereof or a mixture thereof:
- formula (I) wherein:
- R2 represents a hydrogen atom or a methyl or ethyl radical;
- R3 represents a linear C1-C12 alkyl radical (saturated), optionally substituted with a hydroxyl group;
- or a linear C2-C12 alkenyl radical (C═C unsaturated), optionally substituted with a hydroxyl group.
