The aim of this study is to optimize the culture conditions for lichen Usnea ghattensis G. Awasthi in order to increase biomass and antioxidant metabolite production. The cultured lichen consisted of usnic acid produced by mycobionts and photobionts after 2 to 3 months of inoculation. Cultures grown in the media with excess carbon sources showed significant increment in the biomass growth, usni...

Lichens are predominant and important components of flora in the terrestrial ecosystem of Antarctica. However, relatively few researches on the phylogenetic position of Antarctic lichen-forming fungi have been accomplished. In this study, partial sequences of nuclear large subunit rDNAs from 50 Antarctic specimens were obtained and the phylogeny was reconstructed. Antarctic lichen species were ...

The aim of this study was to investigate the antifungal effects and molecular changes caused by Usnea longissima Ach. extracts against Fusarium greaminearum. In agar well diffusion assay, zone inhibition increased as concentration in both methanol acetone (1, 10, 20 50 mg/ml). terms bioactivities, 1 mg/ml active, while other concentrations were very active. At level, extract analyzed qPCR with ...
