Characterization of sludges - Detection and enumeration of Salmonella spp. in sludges, soils, soil improvers, growing media and biowastes - Part 1: Membrane filtration method for quantitative resuscitation of sub-lethally stressed bacteria (to confirm eff
This part of the CEN Technical Report specifies a membrane filtration procedure for the quantitative resuscitation and enumeration, by culture of individual colonies on chromogenic agar media, of Salmonella spp. including potentially sub-lethally damaged Salmonella spp. in sewage sludges. It may be suitable for other sludges, soils, soil improvers, growing media and biowastes but the user shall validate the method using these materials. The fully defined scope will be determined after the proposed validation trials have been agreed and carried out.NOTE 1 The objective is to cover untreated and treated sludges, soils, soil improvers, growing media and biowas
