TABLE 1.
Impact of dispersion of samples on CFU counts of unchlorinated and chlorinated suspensions of suspended Sphingomonas cells
| Samples | Avg no. of CFU ml−1 (SD)a
|
|
|---|---|---|
| With no dispersion of aggregates by sonication | After sonication of samplesb | |
| Unchlorinated | 4.6 × 107 (3.9 × 107) | 3.8 × 107 (2.9 × 107) |
| Chlorinated | 2.0 × 101 (0.90 × 101) | 4.0 × 103 (0.90 × 103) |
a
Each value in parentheses indicates the standard deviation of three replicates.
b
Sonication was performed just before pour plating of the samples.
