The “Other” Rickettsiales : an Overview of the Family “ Candidatus Midichloriaceae”

Citation
Giannotti et al. (2022). Applied and Environmental Microbiology 88 (6)
Names
Ca. Midichloriaceae
Abstract
Among endosymbiotic bacterial lineages, few are as intensely studied as Rickettsiales , which include the causative agents of spotted fever, typhus, and anaplasmosis. However, an important subgroup called “ Candidatus Midichloriaceae” receives little attention despite accounting for a third of the diversity of Rickettsiales and harboring a wide range of bacteria with unique features, like the ability to infect m

Candidatus Thiovulum sp. strain imperiosus: the largest free-living Epsilonproteobacteraeota Thiovulum strain lives in a marine mangrove environment

Citation
Sylvestre et al. (2022). Canadian Journal of Microbiology 68 (1)
Names
Ca. Thiovulum imperiosus
Abstract
A large (47.75 ± 3.56 µm in diameter) Thiovulum bacterial strain forming white veils is described from a marine mangrove ecosystem. High sulfide concentrations (up to 8 mM of H2S) were measured on sunken organic matter (wood/bone debris) under laboratory conditions. This sulfur-oxidizing bacterium colonized the organic matter, forming a white veil. According to conventional scanning electron microscope (SEM) observations, bacterial cells are ovoid and slightly motile by numerous small flagella

A catalogue of 1,167 genomes from the human gut archaeome

Abstract
AbstractThe human gut microbiome plays an important role in health, but its archaeal diversity remains largely unexplored. In the present study, we report the analysis of 1,167 nonredundant archaeal genomes (608 high-quality genomes) recovered from human gastrointestinal tract, sampled across 24 countries and rural and urban populations. We identified previously undescribed taxa including 3 genera, 15 species and 52 strains. Based on distinct genomic features, we justify the split of the Methano

Candidatus Kaistella beijingensis sp. nov., Isolated from a Municipal Wastewater Treatment Plant, Is Involved in Sludge Foaming

Citation
Song et al. (2021). Applied and Environmental Microbiology 87 (24)
Names
Ca. Kaistella beijingensis
Abstract
Biological foaming or scumming is a sludge separation problem that has become the subject of major concern for long-term stable activated sludge operation in decades. Biological foaming was considered induced by foaming bacteria.

Genomic Insights into the Ecological Role and Evolution of a Novel Thermoplasmata Order, “ Candidatus Sysuiplasmatales”

Citation
Yuan et al. (2021). Applied and Environmental Microbiology 87 (22)
Names
Ca. Sysuiplasmatales
Abstract
A wide array of archaea populate Earth’s extreme environments; therefore, they may play important roles in mediating biogeochemical processes such as iron and sulfur cycling. However, our knowledge of archaeal biology and evolution is still limited considering that the majority of the archaeal diversity is uncultured.

Relevance of Candidatus Nitrotoga for nitrite oxidation in technical nitrogen removal systems

Citation
Spieck et al. (2021). Applied Microbiology and Biotechnology 105 (19)
Names
Ca. Nitrotoga
Abstract
Abstract Many biotechnological applications deal with nitrification, one of the main steps of the global nitrogen cycle. The biological oxidation of ammonia to nitrite and further to nitrate is critical to avoid environmental damage and its functioning has to be retained even under adverse conditions. Bacteria performing the second reaction, oxidation of nitrite to nitrate, are fastidious microorganisms that are highly sensitive against disturbances. One importan
