Comparison of fluorescence levels for various strains of the B. cepacia complex associated with pMLS7-eGFP

StrainGenomovar or specieseGFP expression (rFU)a
CEP509I193 ± 16
ATCC25416I126 ± 17
CEP484II76 ± 6
K56-2III337 ± 9
C4455III75 ± 10
C5424III260 ± 18
CEP40V405 ± 13
CEP21VI207 ± 9
LB400 Burkholderia sp.127 ± 15
DH5α E. coli 16 ± 16
  • a Values reflect the mean ± standard deviation of eight determinations. Measurements with strain CEP559 (genomovar IV) were not included since this strain exhibited a high level of autofluorescence that interfered with the detection of eGFP-specific fluorescence.
