Transcriptome responses of Lactococcus paracarnosus to different gas compositions and co-culture with Brochothrix thermosphacta.

Lactococcus (Lc.) paracarnosus and the phylogenetically closely related Lc. carnosus species are common members of the microbiota in meat stored under modified atmosphere and at low temperature.

Dellaglioa spp. an underestimated genus isolated from high-oxygen modified-atmosphere packaged meat.

The genus Dellaglioa (D.) actually comprises two species, i.e.

Description of Dellaglioa carnosa sp. nov., a novel species isolated from high-oxygen modified-atmosphere packaged meat.

The study provides a taxonomic characterization of three bacterial strains isolated from high-oxygen modified-atmosphere packaged beef from Germany. The strains of the novel species shared identical 16S rRNA gene sequence to the closely related type strain of Dellaglioa algida. However, the in-silico DNA-DNA hybridization (DDH) values indicate that they belong to a different genomic species.

sp. nov. and sp. nov., two novel species isolated from modified-atmosphere packaged beef steaks.

As part of a study investigating the spoilage microbiome of modified-atmosphere packaged beef from Germany, four novel strains of lactic acid bacteria were isolated and subsequently taxonomically characterized by a polyphasic approach, which revealed that they could not be assigned to known species. The isolates were Gram-staining-positive, coccoid, facultatively anaerobic, non-motile, catalase-negative and oxidase-negative. Morphological, physiological and phylogenetic analysis revealed a distinct lineage within the genus , with and as closest relatives.
