Abstract: The present invention relates to a use of extracellular membrane vesicles of at least one probiotic for preventing or reducing the formation of a biofilm on the surface of a material. The present invention also relates to a method for treating a surface of a material in order to prevent or reduce the formation of a biofilm on the surface, the method comprising a step of bringing extracellular membrane vesicles derived from at least one probiotic into contact with the surface. The present invention further relates to a material comprising extracellular membrane vesicles of at least one probiotic on its surface, or into which extracellular membrane vesicles of at least one probiotic are incorporated.

Abstract: The invention relates to microcapsules intended to protect probiotics, comprising a shell and a core wherein the probiotics are dispersed in the form of biofilms distributed in distinct clusters, characterised in that the shell and the core are composed of pectin. The invention also relates to the method for manufacturing the capsules, the use thereof, and a formulation comprising the microcapsules according to the invention.

Abstract: The subject matter of the present invention is a bacterium or a mixture of bacteria having an antagonistic activity with respect to strains of S. aureus, P. aeruginosa, Streptococcus pyogenes, Enterococcus faecium, Enterobacter cloacae, Proteus mirabilis, Bacteroides fragilis, Staphylococcus epidermidis, Propionibacterium acnes, Candida albicans and/or Malassezia furfur as well as the use thereof in the treatment and/or prevention of infections or colonizations related to those pathogens. The invention pertains to care products containing one or more non-pathogenic antagonistic strains intended to prevent and/or treat infections or colonizations on skin, wounds, mucous membranes and appendages.

Abstract: A method for predicting viability, vitality and stability of bacteria, which are usable in stressing environments, produced in the form of bacterial preparations and packed in a frozen or lyophilised form, includes pre-suspending the bacterial preparations in non-stressing aqueous nutrient medium, carrying out a molecular measurement of at least one type of marker gene whose stress state is representative for each considered bacterium species, measuring intracellular pH and in comparing the measured values with reference and/or reference standard values. The use of the inventive method for controlling quality of stress adaptation of bacterial preparations and for selecting such preparations is also disclosed. The invention in particular relates to malolactic and probiotic ferments.
