Major fluxes of sulphur and dissolved inorganic nitrogen were estimated in Central European mountain ecosystems of the Bohemian Forest (forest lakes) and Tatra Mountains (alpine lakes) over the industrial period. Sulphur outputs from these ecosystems were comparable to inputs during a period of relatively stable atmospheric deposition (10-35 mmol m-2 yr-1) around the 1930s. Atmospheric inputs o...

The estimation of the total sulphur content of urine is an analytical problem presenting some peculiar features. The compounds existing in urine which carry unoxidized sulphur are so stable as to require very vigorous oxidizing agents to convert the sulphur into sulphuric acid, yet the subsequent precipitation of the sulphate must take place in the complete absence of oxidizing agents, as well ...

The wine spoilage yeast species Dekkera bruxellensis, after inoculation in red wines, displayed three survival patterns characterized by: i) initial lag phase followed by growth and sequential death; ii) initial death phase leading to reduced viable counts followed by growth and sequential death; and iii) death phase leading to complete loss of viability. These survival patterns were observed f...

In purple sulphur bacteria of the family Chromatiaceae sulphite oxidation via intermediary formation of adenylylsulphate is an enzymologically well characterized process. In contrast, the role of an alternative direct oxidation pathway via the enzyme sulphite:acceptor oxidoreductase has not been resolved. This paper reports the cloning of the genes encoding the adenylylsulphate-forming enzyme a...

Aspergillus was found as a dominant fungi to associate with brands of bindis. Among three potencies of four homeopathic drugs, Lycopodium 1M, Sulphur 1M, and Sepia 30 showed maximum inhibition zone of Aspergillus niger in inhibition zone technique. In poison food technique, Sepia 30M, Tellurium 30M, Sulphur 1M and Lycopodium 200 showed maximum percentage inhibition against A. niger
