PS 8	0.284 ± 0.004 h	0.14 ± 0.003 h	10
PS 9	0.224 ± 0.004j	0.13 ± 0.004j	9.28

No biofilm (less than 0.120), Moderate (0.120–0.240), strong (>0.240).

One-way ANOVA and LSD were used to analyze the data. The data are the standard error of the mean of three replicates. P-value is less than or equal to 0.05–0.01 for significant differences between means with different letters within a column. There is no significant difference between means in the same column.
