Biodegradation of ortho-cresol by a mixed culture of nitrate-reducing bacteria growing on toluene.

abstract：:To prevent transmission of mycobacterial pathogens, medical devices must be disinfected by germicides with proven mycobactericidal activity. The quantitative carrier test EN 14563 provides an international standard for evaluation of the mycobactericidal activity of disinfectants under practical conditions. However, te...
