Phosphatase activity and lead resistance in Citrobacter freundii and Staphylococcus aureus.
It has been previously reported that strains of Citrobacter freundii and of Staphylococcus aureus accumulated lead as Pb-phosphate when grown on media supplemented with high levels of lead salts. Phosphatase activity, which has been postulated to be involved in lead accumulation, was unrelated to lead resistance, resistant and sensitive cells displaying similar levels and patterns of enzyme activity.
