Antimicrobial activities of alcoholic plant extracts. a Quantitative microtiter plate assay for biofilm formation using MTT method. The effect of both L. inermis and P. oleracea plants extracts were tested on C. albicans compared to no extract as negative control. b Bacterial growth inhibition by crude alcoholic plant extracts. The effect of alcoholic plant extracts on the growth of E. coli, S. aureus, Acinetobacter baumanii, Klebsiella pneumoniae, and Pseudomonas aeruginosa was tested in 24-well micro-plates. c Influence of L. inermis and P. oleracea alcoholic extracts on 24 h-grwoing C. albicans in batch culture. The graph represents the re-inoculation of either alcoholic plant extracts-treated Candida or untreated cultures into fresh antibiotic-free media followed by incubation at 37 °C for 24 h. The data was analyzed using one-way analysis of variance (ANOVA) using Dunnett’s Multiple Comparison Test. P value < 0.05 was considered as significant. The standard error represents the mean of three replicas
