新たな門"Minisyncoccota"の細菌を培養することに成功し、この細菌をMinisyncoccus archaeiphilusと命名。

産総研が新たな門を代表する基準株となるバクテリアを世界で初めて培養するのはこれで5例目。強すぎ

Minisyncoccus archaeiphilus gen. nov., sp. nov., a mesophilic, obligate parasitic bacterium and proposal of Minisyncoccaceae fam. nov., ... and Minisyncoccota phyl. nov. formerly referred to as Candidatus Patescibacteria or CPR www.microbiologyresearch.org/content/jour... #jcampubs

Patescibacteria aka Candidate Phyla Radiation becomes the phylum Minisyncoccota with Minisyncoccus archaeiphilus as the type species. Anaerobic parasitic bacterium grow on #methanogen M. hungatei cells as a host.

I told everyone! 😏 If you want to co-culture CPR/DPANN epibionts, try to filter-purify them and add them into pure cultures. For Minisyncoccus they used 0.45 um filters and a suspected host. I'd recommend 0.2 um filters and a panel of various isolates.

Scientists have successfully cultivated a new bacterial strain, Minisyncoccus archaeiphilus, that parasitizes methanogenic archaea, a first in microbial research, with implications for wastewater treatment.
