The novel genus Brakhagea gen. nov. is constituted by four planctomycetal species isolated from aquatic environments in Northern Germany

Scientific Reports
Four budding and pink-pigmented planctomycetal strains, designated SH449T, SH551T, SH467T, and SH501T, were isolated from diverse environmental sources, including Fjord Schlei (a 42 km brackish arm of the Baltic Sea), ponds and wastewater lagoons in ...

“Candidatus Uabimicrobium helgolandensis”—a planctomycetal bacterium with phagocytosis-like prey cell engulfment, surface-dependent motility, and cell division

mBio
The unique cell biology presented by members of the phylum Planctomycetota has puzzled researchers ever since their discovery. Initially thought to have eukaryotic-like features, their traits are now recognized as exceptional but distinctly bacterial ...

The urinary microbiota of men and women and its changes in women during bacterial vaginosis and antibiotic treatment

Microbiome, 2017
Background The urinary microbiota is similarly complex as the vaginal and penile microbiota, yet its role as a reservoir for pathogens and for recurrent polymicrobial biofilm diseases like bacterial vaginosis (BV) is not clear.

C2α‐carbanion‐protonating glutamate discloses tradeoffs between substrate accommodation and reaction rate in actinobacterial 2‐hydroxyacyl‐CoA lyase

FEBS Open Bio, EarlyView.
Enzymes of the 2‐hydroxyacyl‐CoA lyase group catalyze the condensation of formyl‐CoA with aldehydes or ketones. Thus, by structural adaptation of active sites, practically any pharmaceutically and industrially important 2‐hydroxyacid could be biotechnologically synthesized. Combining crystal structure analysis, active site mutations and kinetic assays,

Rapid Preparation of Electrocompetent Listeria monocytogenes and Enhancement of Transformation Efficiency with cAMP Supplementation

Journal of Food Protection
L. monocytogenes is a significant foodborne pathogen associated with serious health risks. The ability to genetically manipulate this bacterium is critical for understanding its pathogenic mechanisms and developing new interventions.

Evolutionarily divergent DUF4465 domains have a common vitamin B12‐binding function

FEBS Open Bio, EarlyView.
We show that DUF4465 family proteins, widespread across bacteria from gut microbiomes, hydrothermal vents, and soil, share a common vitamin B12‐binding function. These augmented β‐jellyroll proteins bind vitamin B12 via extended loops. Our findings establish sequence‐diverse DUF4465 proteins as a widespread class of B12‐binding proteins, highlighting ...

Friends or Foes—Microbial Interactions in Nature [PDF]

Biology, 2021
Microorganisms are present in nearly every niche on Earth and mainly do not exist solely but form communities of single or mixed species. Within such microbial populations and between the microbes and a eukaryotic host, various microbial interactions take place in an ever-changing environment.

Microbial Diversity in the Human Mouth: Dominant Genera and their Interactions. [PDF]

, 2010
Investigations seeking definition of the microbial diversity present in the human oral cavity have been underway for many years. These investigations seek to define the normal microflora of the oral cavity, as well as the stability of the microflora ...

Microbial glycan microarrays define key features of host-microbial interactions

, 2014
Genomic approaches continue to provide unprecedented insight into the microbiome, yet host immune interactions with diverse microbiota can be difficult to study.
