Abstract: The present invention to the identification of a novel isolated bacterial strain, the Limosilactobacillus reuteri strain which is characterized by a naturally occurring overproduction of riboflavin (vitamin B2) compared to other known strains of lactobacilli. Said strain of the Limosilactobacillus species is deposited under accession number LMG P-32020. In a further aspect, also the uses of said L. reuteri strain are disclosed herein. In particular, the use of said strain in food and feed industry, human and veterinary health, large-scale vitamin production, cosmetics and consumer care products is disclosed.

Abstract: The present invention is directed to a novel isolated bacterial strain of the Lactobacillus casei (L. casei) species. More in particular, the strain of the Lactobacillus casei species deposited under accession number LMG P-30039. The present invention further relates to the novel L. casei strain for use in the treatment and/or prevention of infections and/or immune-related diseases. Also the use of the isolated novel L. casei strain or a composition comprising said strain as an adjuvant to promote an immune response during vaccination is disclosed. Further, the use of said novel L. casei strain or a composition comprising said strain in personal hygiene industry, cleaning industry, biomass production, air purification and food industry is disclosed. In another aspect of the present invention, the use of a L. casei species that has a whole genome G/C content of at least 47.5% and expresses one or more catalase genes or a composition comprising one or more of said L.
