The antimicrobial activity of DMSO extracts of three bryophyte species, two mosses and a liverwort (Atrichum undulatum (Hedw.) P. Beauv., Marchantia polymorpha L. ssp. ruderalis Bischl. and Boisselier, Physcomitrella patens (Hedw.) Bruch and Schimp.) grown in nature and in axenic culture was evaluated by microdilution method against eight bacterial species (Escherichia coli ATCC 35210, Pseudomonas aeruginosa ATCC 27853, Salmonella typhimurium ATCC 13311, Enterobacter cloacae (human isolate), Listeria monocytogenes NCTC 7973, Bacillus cereus (human isolate), Micrococcus flavus ATCC 10240 and Staphilococcus aureus ATCC 6538). All investigated bryophyte extracts are proved to be active against all bacteria tested. In general, extracts made from material grown in nature express better anti-bacterial activity comparing to those made from material grown in laboratory conditions. Some of the bacteria react the same to both extracts and some even better to the extracts made from axenically grown material.
