The 4.3-Mb genome of Lutibaculum baratangense strain AMV1(T), isolated from a soil sample collected from a mud volcano in Andamans, India, is reported. The draft genome of strain Lutibaculum baratangense AMV1(T) consists of 4,300,776 bp with a G+C content of 66.93 mol% and 4,198 predicted coding regions, including 56 RNAs.

Geophysical, temperature, and discrete depthstratified geochemical data illustrate differences between an actively venting mud volcano and a relatively quiescent brine pool in the Gulf of Mexico along the continental slope. Geophysical data, including laser-line scan mosaics and subbottom profiles, document the dynamic nature of both environments. Temperature profiles, obtained by lowering a CT...

Mud volcanoes, ranging in size between 50cm and 800m high, are found both on land and in submarine environments. Their variation in height and shape reflects the driving forces building them and the physical properties of their materials. The driving force behind the construction of mud volcanoes is overpressure of fluidised mud at depth within the sediment column. Although some component of ov...

Mud volcanoes can be large and long lived geological structures that morphologically resemble magmatic volcanoes. Because of their capricious behaviour and their spectacular morphology and landscapes, mud volcanoes have attracted attention since antiquity. More recently, mud volcanoes have become the focus of extensive studies for natural science research, including geologists and biologists. M...

The present study assesses the diversity and composition of sediment bacterial and microeukaryotic communities from deep-sea mud volcanoes (MVs) associated with strike-slip faults in the South-West Iberian Margin (SWIM). We used a 16S/18S rRNA gene based pyrosequencing approach to characterize and correlate the sediment bacterial and microeukaryotic communities from MVs with differing gas seep ...

Mud volcanoes are defined as main elements of geological structures and ways through and within which buried argillaceous loose sediments and lithified rocks. The Gharniaregh Tappeh and Naftelijeh mud volcanoes are the most attractive geomorphological phenomena in continental which appear along the eastern coast of the Caspian Sea. The Naftelijeh mud volcano is more active than Gharniaregh–Tapp...

This is a very interesting study of the influence of frenulate siboglinids on the biogeochemistry of an active mud volcano. The authors demonstrate the alteration of oxygen, sulfide, sulfate, and methane profiles and flux rates by the activity of the frenulate worms. It also makes some strong predictions about the controls on the worm’s growth by the geochemical conditions it inhabits. This is ...

Choline (N,N,N-trimethylethanolamine), which is widely distributed in membrane lipids and is a component of sediment biota, has been shown to be utilized anaerobically by mixed prokaryote cultures to produce methane but not by pure cultures of methanogens. Here, we show that five recently isolated Methanococcoides strains from a range of sediments (Aarhus Bay, Denmark; Severn Estuary mudflats a...
