Summary A simple method that allows testing and characterisation of cadmium binding motifs by large set of immobilized peptides was developed. Hepta- and octapeptides containing cysteine and histidine residues were synthesized on cotton carrier. They were tested for cadmium binding. pH values of half metal dissociation were measured. Test for Cd binding was based on its precipitation with ferrous dipyridyl iodide. Subsequent dissolving of precipitate provided semiquantitative data on relative amount of Cd bound. Observed data for particular peptides corresponded with prediction.Abbreviations

During bacterial oxidation of the arsenopyrite that contaminated a chalcopyrite concentrate, the bioextraction of arsenic from the concentrate was examined. A long-term constant As(III) concentration, representing a large portion of the total arsenic, occurred in the leaching medium. As(III) was not further oxidized, either under bioextraction conditions or by Fe(III) in the presence of the mesophilic bacterium Thiobacillus ferooxidans. These results are discussed in relation to the influence of leaching microorganisms on the form of arsenic in the solution. Dissolved As(III) could be reversed into a solid phase by adsorption of As(III) by forming an iron precipitate.

New earthworm samples from Cyprus are assessed and discussed. A re-evaluation of specimens previously relegated to the Southern Alpine species Perelia nematogena (Rosa, 1903), revealed two independent species: Perelia phoebea (Cognetti, 1913) ,described originally from Rhodes Island, (Greece) and an undescribed species Perelia makrisi sp. n. The new species is similar also to the Levantine Pe. galileana Csuzdi &; Pavlí?ek, 2005 and corroborates the hypotheses that the autochthonous earthworm fauna of Cyprus is of Levantine origin.http://www.zoobank.org/urn:lsid:zoobank.org:pub:FD1996DC-2FFC-42D5-A1D2-005B50E6FC64 相似文献

Lytic enzymes from the hepatopancreas ofHelix pomatia do not induce a uniform digestion of the cell wall ofSchizosaccharomyces pombe over the entire cell surface. Perforations are formed in the growth zones through which a protoplast can locally protrude.
Conditions were found under which the frequency of formation of apical protoplast protuberances is higher than 90% cells with
such protuberances can reverse to normally multiplying cells.

The electrofusion of oriented Schizosaccharomyces pombe cells through apical protoplast-protuberances was demonstrated. The protuberances arose after an exposure of early-exponential phase cells to digestive enzymes from hepatopancreas of Helix pomatia. The orientation of cylindric cells within pearl chains was produced by the application of inhomogenous alternating electric fields. 相似文献

The effect of stimulation of the anterior lobe (AL) of the cerebellum on spinobulbo-spinal (SBS) reflex activity evoked by somatic and splanchnic afferentation was studied in chloralose-anaesthetized cats. Unit activity synchronous with the SBS component of the efferent discharge was observed at the level of motoneurons, descending axons of the dorsolateral and ventral funiculi and neurones of the reticular formation (RF). Conditioning stimulation of the AL inhibited this unit activity. Reticular formation units influenced from the AL had direct contact with segmental structures; these results showed that disappearance of the SBS reflex during AL conditioning is associated with the depressant effect of the cerebellar cortex on the reticular formation. 相似文献
