Formation of stable bdelloplasts as a starvation-survival strategy of marine bdellovibrios.

abstract：:Listeria monocytogenes does not produce siderophores for iron acquisition. We demonstrate that a number of microbial siderophores and natural iron-binding compounds are able to promote the growth of iron-starved L. monocytogenes. We suggest that the ability of L. monocytogenes to use a variety of exogenous siderophore...
