The degeneracy of the genetic code allows for multiple codons to encode the same amino acid. However, alternative codons and amino acids are used unevenly among genes, a phenomenon termed codon-usage bias. Genes regulating amino acid biosynthesis of Salinibacter ruber, an extremely halophilic bacterium were studied in order to determine the synonymous codon usage patterns. Factors responsible f...

A number of reports have demonstrated that microcysts, the resting cells produced by most myxobacteria, are more resistant than the corresponding vegetative cells. Baur (1) showed that mycrocysts of Myxococcus ruber withstood desiccation and wet and dry heat better than did vegetative cells. In 1936, Imshenetsky and Solnetzewa (6) reported comparable findings for Cytophaga hutchinsonil and C. e...

Larvae of the water mite species Hydryphantes clypeatus Thor, 1899 are described for the first time, and redescriptions of the larvae H. dispar (Schaub, 1888) and H. planus Thon, 1899 are presented. The present data suggest that H. clypeatus and H. hellichi Thor, 1899, two species recently considered as a junior synonyms of H. planus resp. H. ruber (Geer, 1787) should be recognized as separate ...

The health-promoting potential of 70% ethanolic extracts of 4 rice varieties fermented with Monascus ruber, Phellinus linteus, Cordyceps sinensis and Agaricus blazei was evaluated mainly focusing on their antioxidative and antimutagenic capacities based on the following parameters: phenolic compound and phytic acid content; inhibitory activity on lipid peroxidation; scavenging activity on DPPH ...
