Abstract:
:In order to select a suitable indicator for monitoring the pathogen regrowth potential of composted biosolids, the growth kinetics of selected bacteria were investigated. Growth parameters of six serovars of Salmonella and three strains of Escherichia coli in sterilized compost were compared. Seeded Salmonella and E. coli grew rapidly, reaching population densities of more than 10(8) g-1 after 30 h of incubation. The specific growth rates of Salmonella serovars and E. coli strains were similar and varied from 0.49 to 0.55 h-1. The specific growth rate of the Salm. Typhimurium isolates was significantly higher than the other bacterial strains. It was concluded that an antibiotic-resistant strain of Salm. Typhimurium can be used as an indicator for a pathogen regrowth potential test.
