Molybdenum accumulation in chlD mutants of Escherichia coli.

PMCID: PMC209742  PMID: 2646274

Abstract

The content of molybdenum in wild-type and chlD cells was measured under a variety of growth conditions to determine if cells with a defective chlD gene were able to accumulate molybdenum. The chlD cells accumulated less molybdenum than wild-type cells did but concentrated molybdenum to a level at least 20-fold higher than the concentration in the culture medium. Molybdenum was present within spheroplasts of chlD cells and was not dialyzable. The chlD cells accumulated as much molybdenum as wild-type cells did when grown in medium containing 0.1 mM molybdate; thus, the capability of incorporation of molybdenum into cellular component(s) was equivalent to that of the wild type under these conditions.
