Two dozen of bryophyte species was collected from native habitat types across Europe to test if the ethanol extract can affect the growth of various microorganisms. After start-up test the ethanol extract did not show any influence on growth and development to Gram-negative bacteria and fungi Candida albicans (ATCC10231). Thus, the further tests focused on the Gram-positive bactreia. The ethanol extract of 5g bryophyte material was macerated in liquid nitrogen, and then extract was evaporated till dry. The dry residue was dissolved in 5ml of methanol. This was used in further analyses by MIC and MBC techniques. The result obtained showed the most effective extracts were those made from Pellia endiviifolia and Bazzania trilobata. Phytopathogenic bacteria and fungi C. albicans showed resistance to extracts of any bryophyte species tested. Gram-positive bacterias, namely Staphylococcus aureus (ATCC25923), Listeria monocytogenes (ATCC19111) and Bacilus subtilis (ATCC6633) were intolerant to extracts of liverworts P. endiviifolia and B. trilobata. MIC value for two above mentioned liverworts extract tested were 7-12mm, while referent antibiotic (rifampicin) inhibitory zone were 15-35mm. The most resistant to any bryophyte extracts was Escherichia coli (ATCC25922), while the most sensitive was B. subtilis (ATCC6633) with MIC values obtained 0.01-0.19 mg/ml. The results obtained show clear antimicrobial potential of P. endiviifolia and B. trilobata, however further research are needed.
