Lichens are known as one of the greatest sources of natural compounds having antibiotic properties which some of them are being used as drugs for special diseases therapy. In current study, inhibitive, bacteriostatic and bactericidal activities of methanol extracts of five lichens derived from Arasbaran, East Azarbaijan Province of Iran including Pleopsidiumgobiensis, Parmelinatiliacea, Anaptychiasetifera and Lecanoraargopholis on some plant derived bacteria such asPseudomonas fluorecens, Bacillus subtillis and Enterobactersp. were studied using disc diffusion and minimal inhibitory and bactericide concentration methods. Methanol extracts of lichens had significant inhibitive effects of studied bacteria other than Enterobactersp. in disc diffusion agar method. A. setifera extracts had less inhibitive in bacteria than others. All lichens extracts had more or less bacteriostatic and bactericidal effects on bacteria. Methanol extracts of all lichens had various bacteriostatic and bactericidal effects on bacteria P. gobiensis and P. tiliaceahad much more bacteriostatic and bactericide comparing two other lichens. Lichens extracts was more inhibitive against B. subtillis. The bacteriostatic and bactericidal reaction of Enterobactersp. to lichen extracts was more than two other bacteria. Regarding results of the results, the lichens extracts could have remarkable potential for studied plant bacteria biocontrol and might be considered as promising agents against pathogens.
