Physiological and metagenomic analyses of microbial mats involved in self-purification of mine waters contaminated with heavy metals

Frontiers in Microbiology, 2016
Two microbial mats found inside two old (gold and uranium) mines in Zloty Stok and Kowary located in SW Poland seem to form a natural barrier that traps heavy metals leaking from dewatering systems.

Testing the efficacy of surface swab sampling to determine postmortem submersion interval (PMSI), using the microbiome colonization of skeletal remains. [PDF]

J Forensic Sci
Abstract Postmortem interval (PMI) estimation contributes valuable information in the medicolegal investigation of decomposed human remains, and estimating the postmortem submersion interval (PMSI) can specifically aid investigations involving victims discovered in aquatic environments.

Microbial Communities Drive Methane Fluxes From Floodplain Lakes-A Hydrological Gradient Perspective. [PDF]

Environ Microbiol
This study examined the impact of methanotrophic bacteria (MOB) and methanogenic archaea (mGen) on CH4 emissions from oxbow lakes at various successional stages, analysing their interactions with physicochemical properties of water. The microbial structure, defined by the MOB/mGen ratio, shows emission rates of CH4 specific to each oxbow type.

Biogeochemistry of an Iron- and Manganese-Rich Stratified Lake: Tasik Biru, Malaysia, as a Modern Model Habitat for the Ancient Ocean. [PDF]

Geobiology
ABSTRACT Tasik Biru is a ~70 m‐deep tropical lake in Malaysia, originating from a water‐filled open pit mine. We investigated the biogeochemistry and microbial community of the lake as a modern model habitat to the stratified ancient ocean. We found that a sharp redoxcline exists at around 50 m depth, related to the decrease of O2 and pH (7.2–6.8 ...

Leveraging core enzyme structures for microbiota targeted functional regulation: Urease as an example. [PDF]

Imeta
We present an innovative methodology that integrates core enzyme identification, protein structural characterization, regulator virtual screening, and functional validation to achieve precise microbiome functional regulation. As a proof of concept, we focused on the regulation of urea decomposition by the rumen microbiota in ruminants. This methodology

The water column of the Yamal tundra lakes as a microbial filter preventing methane emission [PDF]

Biogeosciences, 2021
Microbiological, molecular ecological, biogeochemical, and isotope geochemical research was carried out in four lakes of the central part of the Yamal Peninsula in the area of continuous permafrost. Two of them were large (73.6 and 118.6 ha) and deep (up

Genomic Reconstruction of an Uncultured Hydrothermal Vent Gammaproteobacterial Methanotroph (Family Methylothermaceae) Indicates Multiple Adaptations to Oxygen Limitation [PDF]

, 2015
Hydrothermal vents are an important contributor to marine biogeochemistry, producing large volumes of reduced fluids, gasses, and metals and housing unique, productive microbial and animal communities fueled by chemosynthesis.

Divergent Response of Host-Specific Driven Gut Microbial Stability in Freshwater Gastropods to Cyanobacterial Blooms. [PDF]

Ecol Evol
In this study, two freshwater gastropods (Bellamya aeruginosa and Pomacea canaliculata) were used as controls to study the differences in the effects of cyanobacteria on their gut microbial communities in ponds with the absence of cyanobacterial blooms. Cyanobacterial blooms cause distinct differences in the diversity, community structure, and assembly

Microplastic polymer properties as deterministic factors driving terrestrial plastisphere microbiome assembly and succession in the field

Environmental Microbiology, Volume 25, Issue 12, Page 2681-2697, December 2023., 2023
Abstract Environmental microplastic (MP) is ubiquitous in aquatic and terrestrial ecosystems providing artificial habitats for microbes. Mechanisms of MP colonization, MP polymer impacts, and effects on soil microbiomes are largely unknown in terrestrial systems.
