Microbial interaction between the succinate‐utilizing bacterium Phascolarctobacterium faecium and the gut commensal Bacteroides thetaiotaomicron
Succinate production by Bacteroides thetaiotaomicron supported the growth of Phascolarctobacterium faecium and concomitant propionate production via the succinate pathway. We analyzed the transcripti....

Difficult-to-culture micro-organisms specifically isolated using the liquid-liquid co-culture method – towards the identification of bacterial species and metabolites supporting their growth
In this study, the liquid-liquid co-culture method was applied using faecal samples and specific bacterial species as growth-supporting bacteria. We aimed to isolate new, difficult-to-culture bacteria...

Genome-based reclassification of the genus Lactococcus and two novel species Pseudolactococcus yaeyamensis gen. nov., sp. nov. and Lactovum odontotermitis sp. nov. isolated from the gut of termites
The genus Lactococcus was proposed by Schleifer et al. by separating Lactococcus lactis from the genus Streptococcus. Although the family Streptococcaceae consists of four genera, each genus contains ...

Isolated in just 3 years! (previously, 12 years). We obtained two strains from 'Hodarchaeales', proposed to be closest to our archaeal ancestor. Our analysis suggests the ancestor was an anaerobic, syntrophic, peptidotrophic, archaeon with a simple intracellular structure and possible aerotolerance.
Eukaryotes' closest relatives are internally simple syntrophic archaea
Eukaryotes are theorized to have originated from an archaeal phylum Promethearchaeota (formerly 'Asgard' archaea)1,2. The first cultured representatives revealed valuable insight3,4 but are distantly ...
