“…X. conspersa lichen was effective against Colletotrichum acutatum, C. coccodes and C. gloeosporioides which cause anthracnose in red pepper (Jeon et al, 2009). Laska and Kiercul (2014) studied pharmacologic activity (antibacterial, antiviral and anticancer) of metabolites isolated from X. conspersa lichen. Acetone extract of X. conspersa lichen inhibited biofilm formation of Candida albicans (Millot et al, 2017).…”

Antibacterial properties of Dermatocarpon miniatum (L.) W. Mann and Xanthoparmelia conspersa (Ehrh. ex Ach.) Hale lichens were investigated by disc diffusion and Minimum Inhibitory Concentration (MIC) methods. Antioxidant capacity of the lichens were examined by utilizing 2,2-diphenyl-1picrylhydrazyl (DPPH) radical scavenging activity, 2,2'Azino-bis (3-ethylbenzenotiazoline-6-sulphonic acid (ABTS) radical scavenging activity, metal chelating activity, total antioxidant capacity, determination of total phenolic and total flavonoid contents. Extracts showed antibacterial effect against all bacteria except for Escherichia coli and Salmonella enterica. When compared antibacterial efficiency of the tested lichens, it is concluded that X. conspersa lichen is more active than D. miniatum lichen. DPPH radical scavenging activity of the extracts are increased in the following order: ethanol extract of X. conspersa > acetone extract of D. miniatum > ethanol extract of D. miniatum > acetone extract of X. conspersa. Studied lichen extracts showed relatively weak metal chelating activity. According to the obtained results, it is concluded that D. miniatum and X. conspersa lichen extracts can be alternative antibacterial and antioxidant agents.

This study was conducted to investigate lichen as a typical biomass damage on the surfaces of flagpolesupporting stones in the Beopjusa temple. The lichens present on the flagpole-supporting stones were limited to five species. Two dominant lichen species were identified: Aspicilia sp. and Pertusaria flavicans. One foliose species and one fruticose species, which are rarely observed on crustose lichens, were identified as Xanthoparmelia conspersa and Ramalina sekika, respectively. The lichen inhabiting the black algae layer was confirmed as Leprocaulon textum. ATR-FTIR was performed to analyze the secondary metabolites synthesized by the lichens. By comparing the FTIR spectra of Xanthoparmelia conspersa and Ramalina sekika, the synthesized organic acids were confirmed to differ from each other. Furthermore, the spectral changes and characteristics due to functional groups in the molecules were confirmed.
