BHSL production by P. chlororaphis SPR044 and its TnMod insertion derivatives
Strain | Relative concn of BHSL (μM)a | % BHSL compared to SPR044 |
---|---|---|
SPR044 | 16.0 | 100 |
SPR144 | 0 | |
SPR244 | 0 | |
SPR344 | 4.1 | 26 |
SPR544 | 10.0 | 63 |
SPR644 | 15.5 | 97 |
SPR744 | 6.0 | 37 |
SPR844 | 6.4 | 40 |
BHSL production was quantified in well diffusion assays by using cell-free supernatants of stationary-phase cultures. Representative results from four experiments are shown.
