Antimicrobial activity of certain bryophytes.

摘要

The antibacterial effect of Plagiochasma articulatum (A. liverwort) and Fissidens bryoides (A. moss) was evaluated on some bacterial strains such as Agrobacterium tumifaciens, Streptomyces scabies and Xanthmonas citri. The solvent used for the extract preparation was water. The in vitro antibacterial activity was performed by streak plate disc diffusion method (Spdd). P. articulatum extract was more potent than F. bryoides against all selected test microorganisms. Further it was concluded that S. scabies showed maximum growth inhibitory activity followed by X. citri and A. tumifaciens. The results obtained in the present work suggest that both the bryophytes can be used for the treatment of plant diseases caused by these test microorganisms.
