a new solution aiming at coal biodesulphurization has been developed based on the use of bacteria. the most frequently used species of bacteria for removal of inorganic sulphur compounds are thiobacillus ferrooxidans, thiobacillus thiooxidans and thiobacillus acidophilus. in this study the coal sample was decomposed initially and desulphurization experiments was carried out in pure and mixed cu...

A new spray reagent with copper, ammonium molybdate, and sulphuric acid for the detection of phospholipids on thin-layer chromatograms is described. The specificity and sensitivity of the spray reagent is also shown.

Phenols were detoxified in the Onycophoran Peripatoides novaezealandiae by conjugation with sulphuric acid and phosphoric acid, but no evidence for a glycoside detoxication could be found. [14C]Benzoic acid was metabolized in 24h to N2-benzoyl-L-histidine, which was identified by electrophoresis, chromatography and dilution analysis. Similar conjugates were formed with p-aminobenzoic acid and p...

Experiments on sulphuric acid nucleation in low oxygen atmospheres were done order to investigate the role of Archean atmosphere. Nucleation initiated by photolysis SO 2 and subsequent reaction between atomic O was measured with a PSM separate CPC. The parameters < 10 ppm varying levels (4 from 40 105 ppb), RH (3 0 51%), UV light (254 nm, 4 55 100% power), ionization (2 levels: Background ( ∼ 3...
