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(More)
Various solvent extracts of the lichen Usnea ghattensis showed good antioxidant activity. A methanol extract prevented lipid peroxidation by 87% followed by 65% in Trolox at 20 μg/ml. It also showed superoxide anion scavenging activity and free radical scavenging activity 56% and 73%, respectively. The known antioxidants butylated hydroxytoluene (BHT),(More)
The lichen species namely Usnea ghattensis, Heterodermia podocarpa, Arthothelium awasthii and Parmotrema tinctorum have been cultured in vitro and were screened for their antioxidant and antibacterial potential using different assay systems. The methanol extract of lichens showed antioxidant and antibacterial activities according to the order U.(More)
The biologically active compounds, antioxidant activities and free radical scavenging effects of dry matter of cultural medium (DMCM), filtrate (DMF) and different solvent extracts of mycobiont from lichen species Usnea ghattensis in submerged culture (UGSC) were investigated. DMF showed the strongest inhibition of lipid peroxidation as a function of its(More)
The study was aimed to optimize the culture conditions for the production of usnic acid in the cultured cell aggregates composed of symbionts in lichen Usnea ghattensis in vitro. The cultured lichen tissue composed of symbionts appeared after about 2-3 weeks of inoculation in water-agar and malt-yeast extract (MYE) media and shown the production of usnic(More)
Lichen species Usnea ghattensis, Heterodermia podocarpa, Arthothelium awasthii and Parmotrema tinctorum have been cultured in vitro and screened for their antioxidant, antimicrobial and antityrosinase potential using different assay systems. The methanol extract of lichens showed antioxidant, antimicrobial and antityrosinase activities according to the(More)
Protoplasts isolated from the mycobiont of a cultured lichen Usnea ghattensis were fused with protoplasts of the fungus Aspergillus nidulans in order to increase the growth rate of the cultured lichen mycobiont in vitro. The maximum protoplast yield (102 × 104/g fresh cell mass) was reached in citrate buffer with 50 mmol/L 2-sulfanylethanol(More)
