Reduction of surface sulphur upon microbial devulcanization of rubber materials
(1998) In Biotechnology Letters 20(7). p.637-642- Abstract
- Thiobacillus ferrooxidans, T. thioparus, Acidianus brierleyi and TH2 Lund, an archaeal isolate, were tested for sulphur oxidising capacity on ground rubber from spent car tyres. T. ferrooxidans converted 8% (w/w) of the sulphur in cryo-ground spent rubber to sulphate in 20 days. Desulphurization of fresh made natural rubber was studied with scanning electron microscope with energy-dispersive x-ray spectrometer and electron spectroscopy for chemical analysis. The average depletion of sulphur on the treated surface was 24% compared to the bulk region. Oxidised sulphur species were detected on the surface after microbial treatment.
