Draft Genome Sequence of the Thermophilic Acetogen <i>Moorella humiferrea</i> DSM 23265
No full textABSTRACT
Moorella humiferrea
is an endospore-forming, anaerobic, and thermophilic bacterium which was isolated from a terrestrial hydrothermal spring.
M. humiferrea
is able to use humic acid or 10-anthraquinone-2,6-disulfonate as an electron-shuttling compound for growth and Fe(III) reduction. The genome has a size of 2.629 Mb and contains 2,668 predicted protein-coding genes.

Outcrop analogue study to determine reservoir properties of the Los Humeros and Acoculco geothermal fields, Mexico
No full textThe Los Humeros geothermal system is steam
dominated and currently under exploration with 65 wells
(23 producing). Having temperatures above 380 ◦C, the
system is characterized as a super hot geothermal system (SHGS). The development of such systems is still challenging due to the high temperatures and aggressive reservoir fluids which lead to corrosion and scaling problems. The
geothermal system in Acoculco (Puebla, Mexico; so far only
explored via two exploration wells) is characterized by temperatures of approximately 300 ◦C at a depth of about 2 km.
In both wells no geothermal fluids were found, even though
a well-developed fracture network exists. Therefore, it is
planned to develop an enhanced geothermal system (EGS).
For better reservoir understanding and prospective modeling, extensive geological, geochemical, geophysical and
technical investigations are performed within the scope of the
GEMex project. Outcrop analogue studies have been carried
out in order to identify the main fracture pattern, geometry
and distribution of geological units in the area and to characterize all key units from the basement to the cap rock regarding petro- and thermo-physical rock properties and mineralogy. Ongoing investigations aim to identify geological and
structural heterogeneities on different scales to enable a more
reliable prediction of reservoir properties. Beside geological
investigations, physical properties of the reservoir fluids are
determined to improve the understanding of the hydrochemical processes in the reservoir and the fluid-rock interactions,
which affect the reservoir rock properties
