THE UTILIZATION OF CERTAIN SULFUR-CONTAINING COMPOUNDS FOR GROWTH PURPOSES

Sulfur-containing compounds from Clinacanthus siamensis.

Two new sulfur-containing compounds, trans-3-methylsulfonyl-2-propenol (1) and trans-3-methylsulfinyl-2-propenol (2) were isolated together with trans-3-methylthioacrylamide (3), entadamide A (4) and entadamide C (5) from the leaves of Clinacanthus siamensis. The structures were established on the basis of the spectroscopic data. The compounds were tested for antimalarial and antimycobacterial ...

The Study of Biological Technologies for the Removal of Sulfur Compounds

    Combustion of sulfur components of fossil fuels such as oil causes the emission of SO2 in the atmosphere and lead to the formation of acidic rain in the environment. The conventional approach for desulfurization of fossil fuels is the chemical procedure of hydrodesulfurization (HDS). However, this method has low efficiency for desulfurization of ring components of sulfur such as dibenzothio...

Studies of bromine-oxidizable sulfur-containing compounds in mold metabolism.

Oxidation of Some Biologially Active and Related Sulfur Containing Compounds

Earlier works on oxidation of sulf ides, thiols, and disulf ides with both chemical and enzymic systems are reviewed. Enzymic oxidations of thiols and disulfides are compared with their chemical oxidations with N2O and H2O2 by the use of unsymmetrical disulf ides, thiolsulfinates and O18_ tracer technique. In both enzymic oxidation and that with N2O, oxidation of disulfides to thiolsulfinates i...
