Heterotrophic bacteria were isolated from soil and glass slides and classified as Bacillus cereus SNK12, Paenibacillus polymyxa SNK2, Azotobacter chroococcum ANKII, and Ochrobacterium intermedium ANKI. Their cultures could degrade azobenzene under the conditions of co-metabolism. A rapid test for the ability of bacteria to convert azobenzenes is proposed. 相似文献

Nestbox provision is a technique used to increase nest-site availability for secondary cavity-nesting birds. However, little is known about the demographic consequences of nestbox provision in different habitat types. To assess how nestbox provision affects the density of hole-nesting birds simultaneously in two contrasting habitats, we compared the breeding density of Great Tits along transects without nestboxes with that in transects where nestboxes were provided. Although the initial density of breeders was considerably higher in the deciduous habitat than in the coniferous habitat, provision of nestboxes increased density by a similar number of additional pairs in each habitat type. Thus, the provision of nestboxes in managed coniferous forests may be as effective in increasing the breeding opportunities of cavity nesters as in deciduous stands. Moreover, previous research showed that pairs in deciduous habitat with nestboxes have consistently lower breeding success than those in coniferous habitat with nestboxes. It is possible that the addition of nestboxes in the preferred habitat increased density to such an extent that density-dependent effects became apparent. 相似文献

Morphological and biochemical properties of the nitrogen-fixing strain Ochrobactrum intermedium ANKI, intensely growing on media with azo compounds, and its resistance to various common xenobiotics were investigated. The kinetics of azobenzene conversion by O. intermedium ANKI was studied. Under cometabolism conditions, up to 40 mg of azobenzene per liter of medium were decolorized within one week. It was shown that the strain possessed molybdenum-dependent nitrogenase activity, and its nitrogenase system was sensitive to oxygen and fixed nitrogen in the medium. 相似文献

Rapid progress in genome research creates a wealth of information on the functional annotation of mammalian genome sequences. However, as we accumulate large amounts of scientific information we are facing problems of how to integrate and relate the data produced by various genomic approaches. Here, we propose the novel concept of an organ atlas where diverse data from expression maps to histological findings to mutant phenotypes can be queried, compared and visualized in the context of a three-dimensional reconstruction of the organ. We will seek proof of concept for the organ atlas by elucidating genetic pathways involved in development and pathophysiology of the kidney. Such a kidney atlas may provide a paradigm for a new systems-biology approach in functional genome research aimed at understanding the genetic bases of organ development, physiology and disease.Key Words: EuReGene, kidney, genome, development, pathophysiology, genetics 相似文献
