Eradicating (a–c) and inhibitory (d) activity of inulin–LCS on S. aureus biofilm was investigated. Florfenicol (250 μg/mL) was used as a positive control. The activity of biofilm eradication of inulin (1000 μg/mL), LCS (1000 μg/mL), their mixture (1000 + 1000 μg/mL) and inulin–LCS (1000 μg/mL) was determined by MTT assays (a). The concentration-dependency of inulin–LCS against biofilms was compared with LCS (b). After treatment with 1000 μg/mL of each sample, the biofilms were harvested for fluorescence image assay (c). Scale bar, 50 μm. The activity of biofilm inhibition of inulin (1000 μg/mL), LCS (1000 μg/mL), their mixture (1000 + 1000 μg/mL) and inulin–LCS (1000 μg/mL) was also measured by MTT assays (d). Data are represented as the means ± SD (n = 3). * p < 0.05 or ** p < 0.01, compared to the control or corresponding group.
