[Hydroxamate siderophore effect on growth of enterococci].

In eleven strains of genus Enterococcus relation between hydroxamate siderophore production and growth in iron-restricted liquid medium was investigated. Fe(III) deficiency caused moderate decrease of growth rate: the exponential growth phase was prolonged and yield of bacterial mass was lower. The hydroxamate siderophore was produced by all strains but occurred at different phase of growth. Only part of strains showed classical pattern of growth kinetic and siderophore synthesis.
