Application

Toluene may be used for the sterilization of microbial cultures and lyse bacterial cells in the assay of bacterial enzymes. It may be used as solvent for the fabrication of high-resolution 3D structures of polylactide-based materials, via multi-photon polymerization. It was used for the activation of glass slides, for the in vitro test system for allergy diagnosis.

General description

Toluene, a benzene analog, is widely employed as an organic solvent. It has been reported to be a biotoxic solvent that kills most microorganisms at low concentrations (0.1%v/v). Its anaerobic degradation to CO2, by the denitrifying bacterium Thauera arornatica has been reported. It forms syndiotactic polystyrene-toluene molecular compound. Crystal structure of this molecular compound has been investigated by X-ray diffraction studies.
