Algicidal effects of size-fractionated (>3 and <3 kDa) cell-free supernatant of BEP medium (control), wild type strain S51107, nprR-nprX mutant, nprR-nprX [pHT304-RX] mutant, nprR-nprX [pHT304-R] mutant, nprR-nprX [pHT304-R] mutant + SKPDIVG and nprR-nprX [pHT304] mutant on M. aeruginosa 9110. The cell densities of M. aeruginosa 9110 was counted after 48 h. As a control, BEP medium was fractionated and the algicidal activities of the filtrates were monitored. The data are the averages of three independent experiments (error bars are SD from mean values). Different letters indicate statistically significant differences (P < 0.05).
