Brytella acorum gen. nov., sp. nov., a novel acetic acid bacterium from sour beverages
Syst Appl Microbiol. 2023 Jul 4;46(5):126440. doi: 10.1016/j.syapm.2023.126440. Online ahead of print.ABSTRACTPolyphasic taxonomic and comparative genomic analyses revealed that a series of lambic beer isolates including strain LMG 32668T and the kombucha isolate LMG 32879 represent a novel species among the acetic acid bacteria, with Acidomonas methanolica as the nearest phylogenomic neighbor with a valid name. Overall genomic relatedness indices and phylogenomic and physiological analyses revealed that this novel species was best classified in a novel genus for which we propose the name Brytella acorum gen. nov., sp. nov...

Describing difficult-to-culture bacteria: Taking a shortcut or investing time to discover something new?
Syst Appl Microbiol. 2023 Jun 30;46(5):126439. doi: 10.1016/j.syapm.2023.126439. Online ahead of print.ABSTRACTDespite the growing interest in isolating representatives of poorly studied and as-yet-uncultivated bacterial phylogenetic groups, these microorganisms remain difficult objects for taxonomic studies. The time required for describing one of these fastidious bacteria is commonly measured in several years. What is even more problematic, many routine laboratory tests, which were originally developed for fast-growing and fast-responding microorganisms, are not fully suitable for many environmentally relevant, slow-grow...

Expanding the rumen Prevotella collection: The description of Prevotella communis, sp. nov. of ovine origin
We examined six strains in genomic and phenotypic detail, two of which may actually be the same strain isolated nearly three weeks apart. Other strains formed clearly diverged intraspecies lineages as evidenced by core genome phylogeny and phenotypic differences. Strains of the proposed new Prevotella species are strictly saccharolytic as is usual for rumen Prevotella, and use plant cell-wall xylans and pectins for growth. However, the range of cell-wall polysaccharides utilised for growth is rather limited compared to rumen generalists such as Prevotella bryantii or Prevotella ruminicola and this extends also to the inabi...
