Over the last 20 years investigations of the deep hypersaline anoxic basins at the bottom of the oceans have revealed a complex microbial ecology with very diverse and unique metabolisms.

Conductive pili wire electroactive biofilms of Geobacter bacteria and mediate interactions with cytochromes needed to generate electrical currents and mineralize metals.

The authors used meta-analysis to examine whether greenhouse studies of plant-growth-promoting bacteria predict their performance in the field and the conditions under which these biofertilizers are most effective.

A computational pipeline ranking resistome risk for given environmental samples based on shotgun metagenomic sequencing data was developed.

This paper explores low-temperature anaerobic digestion of a synthetic sewage-based wastewater with a focus on microbial community adaptation when using a mesophilic starting community.

Novel simulated intestinal medium to assess microbial neurochemical production.

Our results demonstrate the establishment of distinct microbial communities within ephemeral glacial meltwater habitats, with DOM-microbe interactions playing an integral role in shaping communities on local and polar spatial scales.

Bacteria play an important role in pine wilt disease development and may be targets for biological control.

Impaired sucrose metabolism results in higher levels of Lactobacillus plantarum survival in the murine digestive tract and alters L. plantarum effects on the gut microbiome.

The relationship between sucrose concentration and virulence in Streptococcus mutans biofilm follows a second-order polynomial curve with a turning concentration range from 0.6% to 2.4%.

Limited influence of hospital wastewater on the microbiome and resistome of wastewater in a community sewerage system

New insights in the complex biology of a group of macronuclear-specific bacterial symbionts reveal their advanced adaptation to a broad range of host species and their surprisingly large phylogenetic distance to Holospora species, to which they originally have been assigned.

Shewanella putrefaciens isolated from shrimp Penaeus orientalis increased the virulence factors of Vibrio parahaemolyticus through degradation of quorum-sensing luxM products.

Nanomolar O₂ concentration induces terminal oxidases in marine bacteria.

Fungal communities vary with soil depth in deep loess soils.

Populations of subsurface organisms respond to small changes in electron acceptor availability.

Our results from a glacierized catchment on Qeqertarsuaq (Disko Island) suggest that microbial assemblages exported from glaciers by meltwater are shaped through the mobilization of available source material.

Genomic analyses of Psychrobacter strains revealed several clusters with distinct characteristics that correlated with habitat (marine, terrestrial or warm-host associated).

Native plant growth-promoting bacteria (PGPB) induced positive effects on plant growth and nutrient acquisition with no impact on the rhizosphere microbiome, indicating a rhizosphere microbial community resilient to native PGPB inoculation.

Bacteria use eDNA filaments to build biofilms on the hyphae of ECM fungi and biofilm formation is regulated by several biotic factors.
