Table 1 Comparative susceptibility of bacterial biofilms to metalloid oxyanions with 4 hours of exposure

From: High-throughput metal susceptibility testing of microbial biofilms

Strain Metal MIC (mM) MBC (mM) MBEC (mM) Fold tolerance1
E. coli TG1 SeO32- > 5.8 > 5.8 > 5.8 na
  TeO32- 0.02 ± 0.01 0.03 ± 0.02 > 2.0 ≥ 133
P. aeruginosa ATCC 27853 SeO32- > 187 > 187 > 187 na
  TeO32- 1.6 ± 0.8 6.6 ± 3.0 > 16 2.4
  1. na indicates a measurement that is not applicable
  2. 1the fold tolerance, given the sensitivity of the assay on a log2 scale, is equal to the ratio of the means of MBEC:MBC
