Increasing transposase abundance with ocean depth correlates with a particle-associated lifestyle

mSystems
Transposases are mobile genetic elements that move within and between genomes, promoting genomic plasticity in microorganisms. In marine microbial communities, the abundance of transposases increases with depth, but the reasons behind this trend remain ...

Water Masses and Depth Structure Prokaryotic and T4-Like Viral Communities Around Hydrothermal Systems of the Nordic Seas

Frontiers in Microbiology, 2018
The oceanographic features of the Nordic Seas, situated between Iceland and Svalbard, have been extensively studied over the last decades. As well, the Nordic Seas hydrothermal systems situated on the Arctic Mid-Ocean Ridge System have received an ...

Microbiology and Ecology of Methylated Amine Metabolism in Marine Ecosystems.

Current Issues in Molecular Biology, 2019
Methylated amines (MAs) are ubiquitous in marine ecosystems, found from surface seawaters to sediment pore waters. These volatile ammonium analogs play important roles in biogeochemical cycles of carbon and nitrogen in the marine water column.

Virus isolation studies suggest short-term variations in abundance in natural cyanophage populations of the Indian Ocean [PDF]

, 2006
Cyanophage abundance has been shown to fluctuate over long timescales and with depth, but little is known about how it varies over short timescales. Previous short-term studies have relied on counting total virus numbers and therefore the phages which ...

Electrochemistry and microbiology of microbial fuel cells treating marine sediments polluted with heavy metals

RSC Advances, 2018
The industrial contamination of marine sediments with chromium, copper and nickel in Penang, Malaysia was addressed with bio-remediation, coupled with power generation, using in situ sediment microbial cells (SMFCs) under various conditions.

Hydrothermal activity lowers trophic diversity in Antarctic sedimented hydrothermal vents [PDF]

, 2016
Sedimented hydrothermal vents are those in which hydrothermal fluid vents through sediment and are among the least studied deep-sea ecosystems. We present a combination of microbial and biochemical data to assess trophodynamics between and within ...

Similarities and differences in gastrointestinal microbiomes between wild and human-cared spotted dolphins (Stenella attenuata) in natural waters

Water Biology and Security
Despite the growing awareness on the importance of gut microbiomes, understanding marine mammal gut microbiomes remains limited due to difficulties in sampling. Spotted dolphins (Stenella attenuata) are widely spread oceanic cetaceans, and there is a gap

Quantitative Viral Community DNA Analysis Reveals the Dominance of Single-Stranded DNA Viruses in Offshore Upper Bathyal Sediment from Tohoku, Japan

Frontiers in Microbiology, 2018
Previous studies on marine environmental virology have primarily focused on double-stranded DNA (dsDNA) viruses; however, it has recently been suggested that single-stranded DNA (ssDNA) viruses are more abundant in marine ecosystems.
