Exploring the Molecular Machinery of Denitrification in Haloferax mediterranei Through Proteomics
Frontiers in Microbiology, 2020 Many proteins and enzymes involved in denitrification in haloarchaea can be inferred to be located between the cytoplasmic membrane and the S-layer, based on the presence of a Tat signal sequence and the orientation of the active site that some of these ...

A two-stage, two-organism process for biohydrogen from glucose [PDF]
, 2006 H2 can potentially be produced in a two-stage biological process: the fermentation of glucose by Escherichia coli HD701 and the photofermentation of the residual medium by Rhodobacter sphaeroides O.U. 001. In a typical batch fermentation, E.

Corrosion protection by anaerobiosis
Water Science and Technology, 2001 Biofilm-forming bacteria can protect mild (unalloyed) steel from corrosion. Mild steel coupons incubated with Rhodoccocus sp. strain C125 and Pseudomonas putida mt2 in an aerobic phosphate-buffered medium containing benzoate as carbon and energy source, underwent a surface reaction leading to the formation of a corrosion-inhibiting vivianite layer [Fe3(

Temperature affects the use of storage fatty acids as energy source in a benthic copepod (Platychelipus littoralis, Harpacticoida) [PDF]
, 2016 The utilization of storage lipids and their associated fatty acids (FA) is an important means for organisms to cope with periods of food shortage, however, little is known about the dynamics and FA mobilization in benthic copepods (order Harpacticoida ...

Climate change and temperature dependent biogeography: oxygen limitation of thermal tolerance in animals [PDF]
, 2001 Recent years have shown a rise in mean global temperatures and a shift in the geographical distribution of ectothermic animals. For a cause and effect analysis the present paper discusses those physiological processes limiting thermal tolerance.

Quelques observations sur les conditions de la formation d'anhydride sulfureux en vinification
OENO One, 1985 Les formations importantes de SO2 en vinification en blanc dans les conditions de la pratique pourraient s'expliquer soit par l'intervention de levures particulières soit par des fermentations particulièrement lentes, à basses températures, dans des ...

Involvement of ethylene signalling in a non-climacteric fruit: new elements regarding the regulation of ADH expression in grapevine [PDF]
, 2004 Although grape berries have been classified as non climacteric fruits, ongoing studies on grape ethylene signalling lead to challenge the role of ethylene in their ripening. One of the significant molecular changes in berries is the up regulation of ADH
