Lichens often grow in microhabitats where they experience severe abiotic stresses. Some species respond to high UV radiation by synthesizing dark brown melanic pigments the upper cortex. However, unlike melanized structures of non-lichenized fungi, morphology layer lichens remains unstudied. Here, we analyzed morphology, ultrastructure, and elemental composition UV-exposed thalli lichen Lobaria pulmonaria (L.) Hoffm. Using light microscopy, detected a pigmented sensitive staining with...
Synthetic dyes are widely used in the industry; they chemically stable, difficult to neutralize, and therefore a threat environment when released into wastewaters. The have significant impact on plant performance by impairing photosynthesis, inhibiting growth, entering food chain may finally result toxicity, mutagenicity carcinogenicity of products. Implementation dark piment melanin for adsorption synthetic is new ecologically friendly approach bioremediation. aim present work was study...
Lichens are unique symbiotic organisms from a mutually beneficial alliance of fungi and algae/cyanobacteria that successfully survive extreme temperatures drought conditions. Most probably such extraordinary vitality lichens is underlain by melanins, one the main structural chemical lichen components, their mutual relationship with residual water. In this paper, we propose mechanisms, which allow to store up extra water in structure. Melanins constituents cortical layer presumably contribute...
Lichens are unique extremophilic organisms due to their phenomenal resistance adverse environmental factors, including ultraviolet (UV) irradiation. Melanization plays a special role in the protection of lichens from UV-B stress. In present study, we analyzed binding melanins with components cell walls mycobiont upper cortex melanized lichen thalli Lobaria pulmonaria. Using scanning electron and atomic force microscopy, morphological nanomechanical characteristics layer cells were...
Melanins are universal biopolymers, the main biological function of which is to protect living organisms from adverse factors. Interest in these dark pigments arises due prospects for their use medicine, cosmeceuticals, bioremediation, bioelectronics, and other fields. In this work, a complex scheme was developed isolate melanins lichen Leptogium furfuraceum (Harm.), symbiotic extremophilic organism. Screening conditions extraction melanin, its subsequent precipitation purification made it...

Melanin is a highly polymeric pigment containing phenolic and indole groups. A diversity of melanin types results from differences in the chemical structure elemental composition these pigments. In symbiotic lichens, melanins are synthesized constitutively as part development or can be induced by UV. Melanins provide protection against solar radiation oxidative stress. However, physico-chemical properties melanins, which determines their protective functions remain understudied. The main aim...
