abstract：:H(2)O(2) levels accumulated by Mycoplasma pneumoniae can be influenced by carbon source, different horse sera, yeast extract, thallium acetate, or growth in a simplified, dialyzed medium. Thus, increased levels of H(2)O(2) were detected by growth in glycerol, by omission of thallium acetate, and by the use of dialyzed...
