Three species of the lichen Usnea (U. baileyi (Stirt.) Zahlbr., U. bismolliuscula Zahlbr. and pectinata Stirt.) nine associated endolichenic fungi (ELF) were evaluated using a metabolomics approach. All investigated crude extracts afforded antibacterial activity against Staphylococcus aureus (minimum inhibitory concentration (MIC): 0.0625 mg/mL), but none was observed Escherichia coli, while EL...

The literature review and analysis of a herbarium fruticose epiphytic lichens Usnea (genus: Dill. Ex Adans.) from 450 points located in the Moscow region (Moscow Oblast – MO) showed presence five species territory. These can be found on branches spruce pine, less often birch, some finds are noted black gray alder, rowan, willow. emergence development MO is possible strictly certain conditions. ...

introduction: α-amylase is a major form of amylase found in humans and other mammals. it is the special key enzyme involved in carbohydrates breakdown. inhibition of this enzyme could be used in treatment of diabetes. in this study, the effect of ten iranian macrolichens on alpha amylase were tested. methods: different concentrations of the extracts (25, 50 and 75 mg/ml) were incubated with enz...

Pseudevernia furfuracea L. (Zopf), Peltigera praetextata (Flörke ex Sommerf.) Zopf, Lobaria pulmonaria (L.) Hoffm., and Usnea longissima Ach. lichen species were used as bioindicators to assess the genotoxicity of air pollutants. In the present study, we examined significant environmetal pollutants and investigate how changes may lead to damage in DNA structure using RAPD markers. In the study ...

BACKGROUND At initial steps of rehydration from cryptobiosis of anhydrobiotic organisms or at rehydration of dry tissues the liquid 1H NMR signal increased anomaly. The surplus in liquid signal may appear if some solid constituents dissolved, or if they were decomposed by enzymatic action. METHODS Hydration kinetics, sorption isotherm, 1H NMR spectra and high power relaxometry were applied to...

BACKGROUND The aim of the study was to document the prevailing indigenous knowledge and various uses of lichens among the lichenophilic communities in the hills and mountainous settlements of Nepal. METHODS Ethnic uses were recorded during twelve field trips, each of roughly 15 days in three consecutive years, through direct questionnaires administered to 190 respondents. Lichen samples were ...
