FIG 4.
Concentration of the main produced HMAQs among Bcc species when cultured in tryptic soy broth. HMAQ-C7:2′ and HMAQ-C9:2′ were quantified by LC-MS with a lower limit of detection of 50 μg/liter for each molecule in the total culture. Tested strains are grouped by species. The production of HMAQs was quantified in three biological replicate cultures for each strain, and each dot represents the average HMAQ production for each strain, in milligrams per liter. Lines represent the production average for the clinical and environmental strains.
