چکیده
In this study, the antimicrobial activity of the acetone, diethyl ether and ethanol extracts of the lichen Cetraria aculeata has been investigated. The extracts were tested against twelve bacteria and eight fungi and found active against Escherichia coli, Staphylococcus aureus, Aeromonas hydrophila, Proteus vulgaris, Streptococcus faecalis, Bacillus cereus, Bacillus subtilis, Pseudomonas aeruginosa, Listeria monocytogenes. No antimicrobial activity against the fungi was detected. It was determined that only one substance in the extracts has antimicrobial activity and it was characterized as protolichesterinic acid. The MICs of the extracts and protolichesterinic acid were also determined.

In this study, the mutagenic and anti-mutagenic effects of methanol extract of three lichen species (Cetraria aculeata, Cladonia chlorophae and Certalia olivetorum) were investigated by using E.coli-WP2, Ames-Salmonella (TA1535 and TA1537) and sister chromatid exchange (SCE) test systems. The results obtained from bacterial test systems demonstrated that methanol extracts of three lichen specie...

PREMISE OF THE STUDY Polymorphic microsatellite markers were developed for the lichen species Cetraria aculeata (Parmeliaceae) to study fine-scale population diversity and phylogeographic structure. METHODS AND RESULTS Using Illumina HiSeq and MiSeq, 15 fungus-specific microsatellite markers were developed and tested on 81 specimens from four populations from Spain. The number of alleles rang...
متن کاملAlphaproteobacterial communities in geographically distant populations of the lichen Cetraria aculeata.
Lichen symbioses were recently shown to include diverse bacterial communities. Although the biogeography of lichen species is fairly well known, the patterns of their bacterial associates are relatively poorly understood. Here we analyse the composition of Alphaproteobacteria in Cetraria aculeata, a common lichen species that occurs at high latitudes and various habitats. Using clone libraries ...
