Geomicrobiology, Fifth Edition
A relatively recently discovered bacterium, Thauera selenatis, can grow
anaerobically with selenate or nitrate as terminal electron acceptor (Macy et al.,
1993; Rech and Macy, 1992). In the absence of nitrate, it reduces selenate to
selenite ...

Protein Nutrition and Mineral Absorption
In experiments with rats, it was demonstrated that selenate is best absorbed in
the ileum, followed by the jejunum and the large intestine. In addition, selenate
absorption in the ileum is a saturable phenomenon. High concentrations of
selenate ...

Selenate dominates under alkaline conditions. In contrast to selenite. selenate,
Se(VI). is highly mobile in soils. Benjamin (1983) found that selenate was
adsorbed by amorphous iron oxide as a function of pH. Maximum removal was at
pH 4.5 ...

moderately reducing groundwater conditions, which favor selenate and selenite
reduction and immobilization. On the other hand, aquifer sediments derived from
the Coast Range (to the west) tend to be more oxidizing, and consequently, ...

Perchlorate reductase from Dechloromonas agitata is different from that of I.
dechloratans, although the pcrAB gene products are similar to α- and β-subunits
of other reductases including nitrate, selenate, and chlorate. The pcrC gene
product ...

selenate reduction (reaction 23, Table I). Unfortunately, the SeS culture has been
lost and is not available for further study (Steinberg et al., 1992). Another
selenate-reducing microorganism, designated SES-3, grew in defined medium
with ...

A lower rate of application would suffice if the sodium selenate was applied as a
foliar spray at ear emergence. Responses in Se concentrations in mature wheat
plants and their fractions to the sodium selenate Table 3 Logarithmic mean flour ...

Chemistry of Trace Elements in Fly Ash
The positive adsorption of selenate only occurred on surfaces with a net positive
charge. There was virtually no adsorption of selenate on the uncoated mineral (
Fig. 4) whose pH0 was 4.26. Actually, the surface charge characteristic data ...

sulfate (from 33mgSL~' with selenate at 0.1, 0.5, or l.0mgSeL~') produced a six-
fold decrease in the concentration of Se in shoots of barley (cv. Briggs) after 28
days in solution culture; similarly a two-fold increase in sulfate (from 16mgSL~'

Progress in Research on Energy and Protein Metabolism
Beside antioxidative functions of the trace element selenium as an integral part of
glutathione peroxidases and thioredoxin reductases, an interesting physiological
aspect for selenate was detected with regard to diabetes. In type I diabetic rats ...
