In this study, the hydrothermal treatment of municipal solid wastes (MSWs) for the production of biochar as a renewable solid fuel was investigated. The properties of surrogate MSWs and mixtures of newspaper and vegetables were greatly improved by hydrothermal treatment and were similar to those of coal-like fuel substances. Hydrothermal treatment increased the calorific value, the fixed carbon...

We report the genome sequence of Thermococcus superprofundus strain CDGS(T), a new piezophilic and hyperthermophilic member of the order Thermococcales isolated from the world's deepest hydrothermal vents, at the Mid-Cayman Rise. The genome is consistent with a heterotrophic, anaerobic, and piezophilic lifestyle.

A knowledge of the stability of iron complexes in hydrothermal solutions is important for quantitative interpretation of the chemical behaviour of iron in hydrothermal systems. It is generally accepted that iron is predominantly transported as Fe(II) species in reduced acid fluids whereas Fe(III) hydroxy complexes become also important in reduced alkaline solutions. Previous studies on iron tra...

One of the promising avenues for biomass processing is the use of water as a reaction medium for wet or aquatic biomass. This review focuses on the hydrothermal catalytic production of fuels and chemicals from aquatic biomass. Two different regimes for conversion of aquatic biomass in hydrothermal conditions are discussed in detail. The first is hydrothermal liquefaction, and the second is hydr...

Geothermobacter sp. strain EPR-M was isolated from a hydrothermal vent on the East Pacific Rise and has been shown to participate in the reduction of Fe(III) oxides. Here, we report its 3.73-Mb draft genome sequence.

Vulcanibacillus modesticaldus BRT was isolated from calcite-rich, metalliferous core samples collected at the Rainbow deep-sea hydrothermal vent field on the Mid-Atlantic Ridge. Here, we report the 2.2-Mb draft genome sequence for this strain, consisting of 100 contigs with a G+C content of 33.6% and 2,227 protein-coding sequences.

The aim of this study is to review of our knowledge about distribution of recently known species of vent shrimps and to analyze factors influencing distribution patterns. Analyses are based upon (1) original material taken during eight cruises in the Atlantic Ocean (a total of 5861 individuals) and (2) available literature data from the Atlantic, Pacific, and Indian Oceans. Vent shrimps have tw...

Pretreatment of corn stover in 0.5% sulfuric acid at 160 °C for 40 min realized a maximum monomeric plus oligomeric xylose yield of 93.1% compared to a maximum of only 71.5% for hydrothermal (no added mineral acid) pretreatment at 180 °C for 30 min. To explain differences in dilute acid and hydrothermal yields, a fast reacting xylan fraction (0.0889) was assumed to be able to directly form mono...
