(Submitter supplied) Propionibacterium freudenreichii, a dairy starter, reaches a population close to 10^9 propionibacteria per gram of Swiss-type cheese at the time of consumption. Also consumed as a probiotic, it revealed strain-dependent anti-inflammatory properties mediated by proteins inducing IL-10 in leukocytes. Here, strains with varied anti-inflammatory potentials were compared in terms of transcriptome profiles.

(Submitter supplied) Summary: Incidence of necrotizing enterocolitis (NEC), which remains a leading and intractable cause of mortality in preterm infants, is attenuated by feeding human breast milk (HBM). We report that this diminution correlates with alterations in the gut microbiota, particularly enrichment of Propionibacterium species. Transfaunation of microbiota from HBM-fed preterm infants, or a Propionibacterium strain, P. more...

(Submitter supplied) Propionibacterium freudenreichii CIRM-BIA138 was grown for 11 days in YEL medium at 30°C without any addition of nutrients. RNA was extracted from bacteria harvested 24 H post-inoculation (exponential phase) and 72 H post-inoculation and was depleted from ribosmic sequences. RNA samples were sequenced on Hiseq 2000 generating single reads of 50 bp.

(Submitter supplied) Mechanisms allowing P. freudenreichii adaptation to digestive stresses have been only studied in vitro so far. Our aim was therefore to study P. freudenreichii metabolic adaptation to intra-colonic conditions in situ. We maintained a pure culture of P. freudenreichii CIRM-BIA1, contained in a dialysis bag, within the colon of vigilant piglets during 24 hours. A transcriptomic analysis identified the metabolic pathways induced by this environment, in comparison with control propionibacteria maintained in spent culture medium.

(Submitter supplied) Propionibacterium freudenreichii is used as a ripening culture in Swiss cheese manufacture. It produces flavor compounds over the whole ripening period. During cheese ripening, P. freudenreichii is exposed to a temperature downshift, especially when cheeses are transferred from warm temperature (about 24°C) to cold temperature (about 4°C). The cold adaptation of the type strain was studied previously. more...

(Submitter supplied) Propionibacterium freudenreichii strains CIRM121, CIRM122, CIRM129, CIRM134, CIRM139, CIRM456, CIRM514, and CIRM516. The design allows to monitor the expression of 2,740 genes (clusters) based on probing 27,546 distinct genomic regions (only 594 genes found in at least 1 of the 8 strains were not covered). On average, the expression of a gene was monitored via 10 distinct probe sequences (corresponding to 20 measures of intensity since each probe was duplicated). more...
