Growth inhibition of Pseudomonas aeruginosa and Enterococcus faecalis by crude extractives of Mansonia altisima timber sawdust.

Crude, aqueous methanol and ethanol extracts of sawdust of Mansonia (Mansonia altisima) timber inhibited Pseudomonas aeruginosa and Enterococcus faecalis. The minimum inhibitory concentration ranged from 4.4 to 9.3 mg/ml, while the minimum bactericidal concentration was 10.0-25.0 mg/ml. Enterococcus faecalis was more susceptible, but no marked difference occurred in the antibacterial effect of methanol and ethanol extracts. The aqueous extract was less active.
