Biofilm formation on acrylic under the different conditions used, in μg biofilm mass mm−2 of acrylic
Strain | 24 h batch | 72 h batch | 72 h fed-batch |
---|---|---|---|
9142 | 1.5 (±0.4)* | 4.9 (±1.4)* | 16.8 (±4.5)† |
9142-M10 | 0.2 (±0.1) | 0.5 (±0.2) | 1.2 (±0.5) |
FJ6 | 2.6 (±0.4)* | 4.2 (±1.2)* | 5.6 (±2.2) |
JI6 | 2.1 (±0.4)* | 3.6 (±1.4)* | 10.2 (±2.3)† |
LE7 | 1.9 (±0.4)* | 3.8 (±1.3)* | 4.2 (±2.3) |
PE9 | 2.5 (±0.4)* | 5.6 (±1.0)* | 12.4 (±4.8)† |
The 24 h batch is significantly different from 72 h batch (P < 0.05, paired t-test).
Significantly higher biofilm formation compared with other strains grown under the same conditions (P < 0.05, anova and Tukey’s multiple comparison test).
