Information regarding the diversity and abundance of oxygenic photoautotrophs in atmosphere is limited. More information from diverse locations needed. These airborne organisms could have important impacts upon atmospheric processes on ecosystems they enter after deposition. Oxygenic photoautotrophic microbes are integral to ecosystem functioning, some potential affect human health. A better understanding movements these aeolian dispersed needed understand their ecology, as well how

Global diversity and distribution of mushroom‐inhabiting bacteria

Environmental Microbiology Reports, Journal Year: 2022, Volume and Issue: 14(2), P. 254 - 264

Published: Jan. 31, 2022

Summary Mushroom‐forming fungi are important sources of food and medicine in many regions the world, their development health known to depend on various microbes. Recent studies have examined structure mushroom‐inhabiting bacterial (MIB) communities association with local environmental variables, but global‐scale diversity determinants these remain poorly understood. Here we MIB global community composition relation climate, soil host factors. We found a core mushroom microbiome, accounting for 30% sequence reads, while comprising few genera such as Halomonas , Serratia Bacillus Cutibacterium Bradyrhizobium Burkholderia . Our analysis further revealed an role phylogeny shaping MIB, whereas effects climate factors remained negligible. The results suggest that free‐living bacteria structured by contrasting assembly processes fungal–bacterial interactions determinant structure.

Seasonal Variation of the Atmospheric Bacterial Community in the Greenlandic High Arctic Is Influenced by Weather Events and Local and Distant Sources

Frontiers in Microbiology, Journal Year: 2022, Volume and Issue: 13

The Arctic is a hot spot for climate change with potentially large consequences on global scale. Aerosols, including bioaerosols, are important players in regulating the heat balance through direct interaction sunlight and indirectly, inducing cloud formation. Airborne bacteria major bioaerosols some species producing most potent ice nucleating compounds known, which implicated formation of clouds. Little known about numbers dynamics airborne even less their seasonal variability. We collected aerosol samples wet deposition spring 2015 summer 2016, at Villum Research Station Northeast Greenland. used amplicon sequencing qPCR targeting 16S rRNA genes to assess quantities composition DNA cDNA-level bacterial community. found clear variation atmospheric community, likely due variable sources meteorology. In early spring, community was dominated by taxa originating from temperate Subarctic regions arriving sampling site long-range transport. observed an efficient washout aerosolized cells during snowstorm, followed very low concentrations atmosphere consecutive 4 weeks. suggest that this because late transport ceased, local comprised only snow surfaces were weak resulting concentrations.

Impact of airborne algicidal bacteria on marine phytoplankton blooms

The ISME Journal, Journal Year: 2024, Volume and Issue: 18(1)

Published: Jan. 1, 2024

Abstract Ocean microbes are involved in global processes such as nutrient and carbon cycling. Recent studies indicated diverse modes of algal–bacterial interactions, including mutualism pathogenicity, which have a substantial impact on ecology oceanic sequestration, hence, climate. However, the airborne dispersal pathogenicity bacteria marine ecosystem remained elusive. Here, we isolated an algicidal bacterium, Roseovarius nubinhibens, emitted to atmosphere primary aerosol (referred also sea spray aerosols) collected above coccolithophore bloom North Atlantic Ocean. The aerosolized retained infective properties induced lysis Gephyrocapsa huxleyi cultures.This suggests that transport through can effectively spread infection agents over vast regions, highlighting its significance regulating cell fate algal blooms.
