Acidithiobacillus ferrooxidans is a strict acidophilic chemolithoautotrophic bacterium that obtains its energy from reduced inorganic sulfur species or ferrous iron oxidation under aerobic conditions. Carbon felt electrodes were pre-colonized by A. ferrooxidansATCC 23270T using ferrous iron or sulfur as electron donors, via the addition (or not) of a mixture of C14 acyl-homoserine lactones (C14...

This year, 1976, the Nobel Prize in Chemistry has been awarded for research in pure inorganic chemistry, in particular the boranes. May I say that I am most pleased and profoundly grateful. My own orientation to this field has been, as it has in all of my studies, the relationships of the chemical behavior of molecules to their three-dimensional geometrical and electronic structures. The early ...

Background: Liver is a complex organ, essential for iron metabolism in the body and recognised as primary site synthesis of iron-related plasma proteins. also regulates concentrations an effective manner identifies changes systemic requirements. Haematological abnormalities are often associated with chronic liver diseases. Raised stores shows high response to infection hepatitis C, resistance i...

Chelating is the chemical process by which a mineral (iron, cobalt, copper, zinc, and manganese) is combined with a mixture of amino acids and peptides. The resulting substances are known as chelates. Another descriptive term, proteinates, refers to the amino acid bond. These chelated minerals are thought to be more digestible than nonchelated forms. In other words, chelation makes the minerals...

Iron deficiency anemia is the most common type of anemia related to malnutrition world wide. It represents a major problem in developing countries, especially in Egypt. The aim of this study was carried out to elucidate the effect of different types of oral iron therapy (used for the treatment of iron deficiency anemia) on some hormones and minerals in anemic rats. Forty weanling male Sprague-D...

The 2.2-A X-ray structure for CCP(MI), a plasmid-encoded form of Saccharomyces cerevisiae cytochrome c peroxidase (CCP) expressed in Escherichia coli [Fishel, L.A., Villafranca, J. E., Mauro, J. M., & Kraut, J. (1987) Biochemistry 26, 351-360], has been solved, together with the structures of three specifically designed single-site heme-cleft mutants. The structure of CCP(MI) was solved by usin...

Currently, about 80% of chemical and biological science research in the world is claimed by the discipline of biochemistry. The major reason for this lion share is that biochemistry forms a strong foundation on which stands the whole model of all biological and medical sciences. That is why the spectrum of teaching and research activity in biochemistry embraces large number of fields such as mo...

Phaeocystis antarctica is an abundant phytoplankton species in the Southern Ocean, where growth is frequently limited by iron and light. Being able to grow under low iron conditions is essential to the species' success, but there have been hints that this ability differs among clones. Here, we compare the growth, cell size and chlorophyll a concentrations of four P. antarctica clones cultured u...
