Abstract: 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. & Boisselier, Physcomitrella patens (Hedw.) Bruch & 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.
Abstract: In this study, the deposition of three heavy metals (Pb, Sr and Zn) in the county of Obrenovac (Serbia)
in four moss taxa (Bryum argenteum, Bryum capillare, Brachythecium sp. and Hypnum cupressiforme)
is presented. Distribution of average heavy metal content in all mosses in the county of Obrenovac is
presented in maps, while long term atmospheric deposition (in mosses Bryum argenteum and B.
capillare) and short term atmospheric deposition (in mosses Brachythecium sp. and H. cupressiforme)
is discussed and given in tables. Areas of the highest contaminations are highlighted.
