Six species of lichens, such as Usnea florida, Usnea barbata, Usnea longissima, Usnea rigida, Usnea hirta and Usnea subflorida, were collected from different areas of Anatolia (district of Antalya, Karabük, Qankiri, Giresun and Trabzon) in Turkey. Their usnic acid amounts in acetone extracts were determined by HPLC. In addition, antimicrobial activities of these extracts were determined against...

Bacillus stratosphericus strain 5Co was isolated from lichen Usnea florida in central Florida, United States. Here, we report a draft genome sequence of this strain, which consists of 159 contigs spanning 3,628,496 bp, with a G+C content of 41.3% and comprises 3,729 predicted coding sequences.

several lichen species have been used for medicinal purposes throughout the ages, and they were reported to be effective in the treatment of different disorders including tuberculosis, hemorrhoids, ulcer, dysentery and cancer. it is revealed that they may be easily accessible sources of natural drugs that could be used as a possible food supplement or in pharmaceutical industry after their safe...

Usnea Adans. is a somewhat rare lichen in South Korea, and, in nearly two decades, no detailed taxonomic or revisionary study has been conducted. This study was based on the specimens deposited in the lichen herbarium at the Korean Lichen Research Institute, and the samples were identified using information obtained from recent literature. In this study, a total of eight species of Usnea, inclu...

in this study, antioxidant and antimicrobial potentials of usnea intermedia, u. filipendula, and u. fulvoreagens and their stictic and usnic acid contents were investigated. antioxidant activity and total phenolic contents were evaluated in acetone, ethanol, and methanol extracts of these three species. antioxidant activity was measured by abts [2,2'-azino-bis(3-ethylbenzothiazoline-6-sulp...

Lichens are symbiotic associations of fungi with microalgae and/or cyanobacteria, which are considered among the slowest growing organisms, with strong tolerance to adverse environmental conditions. There are about 400 genera and 1600 species of lichens and those belonging to the Usnea genus comprise about 360 of these species. Usnea lichens have been used since ancient times as dyes, cosmetics...

PREMISE OF THE STUDY Usnea antarctica and U. aurantiacoatra (Parmeliaceae) are common lichens in the maritime Antarctic. These species share the same habitats on King George Island (South Shetland Islands, Antarctica) and are distinguishable based on reproductive strategies. METHODS AND RESULTS We developed 23 fungus-specific simple sequence repeat (SSR) markers that cross-amplify between the...

There is cumulative resistance against antibiotics of many bacteria. Therefore, the development of new antiseptics and antimicrobial agents for the treatment of skin infections is of increasing interest. We have screened six plant extracts and isolated compounds for antimicrobial effects on bacteria and yeasts with dermatological relevance. The following plant extracts have been tested: Gentian...
