A study of the carbohydrate metabolism of Sarcina lutea was undertaken to elucidate the routes of metabolism available to this strict aerobe which does not metabolize glucose anaerobically. It was of interest, therefore, to discover whether the organism possesses enzymes characteristic of anaerobic fermentation and, if so, their importance in aerobic glucose oxidation. The process of terminal r...

CuI/TEMPO-Katalysatorsysteme (TEMPO=2,2,6,6-Tetramethylpiperidinoxyl) sind vielseitige Katalysatoren für aerobe Alkoholoxidationsreaktionen zur selektiven Synthese von Aldehyden. Jedoch mehrere Aspekte des Reaktionsmechanismus noch nicht aufgeklärt, was hauptsächlich daran liegt, dass bisher keine reaktiven Intermediate identifiziert werden konnten. Wir zeigen hier die und Charakterisierung ein...

Steroid and hopanoid biomarkers can be found in ancient rocks may give a glimpse of what life was present at that time. Sterols hopanoids are produced by two related enzymes, though the evolutionary history this protein family is complicated losses horizontal gene transfers, appears to widely misinterpreted. Here, I have added sequences from additional species, re-analysis phylogeny SHC OSC ind...

It has been suggested that photoreactivation may occur by a mechanism which is similar to a photosensi­ tised splitting of pyrimidine-dimers1. Since photo­ sensitised processes depend very often on the presence or absence of oxygen, it is of interest in this context to know whether the gaseous environment has any ef­ fect on the photoreactibility of UV-irradiated cells. If the cytochrome system...

Principal component analysis (PCA) was used to comprehensively evaluate the relationship between physicochemical and bacteriological parameters of water on banks Wouri. At each sampling station, focused Water temperature, pH, dissolved oxygen, CO2, electrical conductivity, suspended solids, nitrates, ammonium ions, orthophosphates, color, salinity, turbidity. The consisted isolation heterotroph...

BACKGROUND Pseudomonas putida is a promising host for the bioproduction of chemicals, but its industrial applications are significantly limited by its obligate aerobic character. The aim of this paper is to empower the anoxic metabolism of wild-type Pseudomonas putida to enable bioproduction anaerobically, with the redox power from a bioelectrochemical system (BES). RESULTS The obligate aerob...
