Bacterial communities colonize the surfaces of lichens in a biofilm-like manner. The overall structure bacterial harboured by shows similarities, particular dominance not yet cultured Alphaproteobacteria. Parameters causing variation abundance, composition and spatial organization lichen-associated are so far poorly understood. As first step, we used microscopic approach to test significance both lichen-intrinsic extrinsic environmental factors on associated with 11 lichen samples, belonging...
The genus Asterochloris represents one of the most common, widespread, and diverse taxa lichen photobionts. In this report, we describe characterize six new species (A. echinata, A. friedlii, gaertneri, leprarii, lobophora, woessiae) that were identified during our recent investigation photobiont diversity. We found differed genetically, morphologically, ecologically, with respect to their mycobiont partners. Statistical analyses revealed significant morphological differentiation all newly...
The diversity of green microalgae in subaerial habitats remains largely unexplored and a number new genus- species-level lineages have been discovered recently. traditional algal genus, Chlorella, which accommodated coccoid unicellular species with globular to oval cells, reproducing entirely by autospores, has found be polyphyletic. In this study, we provide detailed characterization two strains isolated from tree bark the Mediterranean. These algae share general Chlorella-like morphology...
Climatic factors, soil chemistry and geography are considered as major factors affecting lichen distribution diversity. To determine how these limit or support the associations between symbiotic partners, we revise symbiosis a network of relationships here. More than one thousand thalli terricolous Cladonia lichens were collected at sites with wide range chemical properties from seven biogeographical regions Europe. A total 18 OTUs algal genus Asterochloris 181 mycobiont identified. We...

Phycologia 52: 411–421. DOI: 10.2216/13–142.1The Watanabea clade the Trebouxiophyceae included mostly unicellular microalgae that thrived in various terrestrial microhabitats. The diversity these morphologically uniform was little known, several new genus-level lineages had recently been described...
Carbon steel is currently being considered as a candidate canister material for use in deep geological repository of radioactive waste. Assessment corrosion through microbial activity an important part the safety assessment final repository. The aim study was to compare and characterise behaviour carbon under sterile non-sterile anaerobic conditions natural groundwater containing sulphate-reducing bacteria (SRB). A molecular-biological approach used determine presence abundance changes...
Lichens are an iconic example of symbiotic systems whose ecology is shaped by the requirements symbionts. Previous studies suggest that fungal (mycobionts) as well photosynthesizing (phycobionts or cyanobionts) partners have a specific range acceptable symbionts can be chosen according to environmental conditions. This study aimed investigate effects climatic conditions and mycobiont identity on phycobiont distribution within lichen genera Stereocaulon, Cladonia, Lepraria. The area comprised...
Abstract Zeorin-containing red-fruited Cladonia species, the so-called C. coccifera group, are widespread terrestrial lichens which share most of their secondary substances but differ morphologically. The main objective this study was to explore whether current delimitation these species is supported by molecular data. A total 52 European and North American specimens , deformis diversa pleurota were examined. internal transcribed spacer regions nuclear ribosomal DNA β-tubulin gene loci...
With rare exceptions, the shape and appearance of lichen thalli are determined by fungal partner; thus, mycobiont identity is normally used for identification. However, it has repeatedly been shown in recent decades that phenotypic data often does not correspond with gene evolution. Here, we report such a case three-species complex red-fruited Cladonia lichens, two which clearly differ morphologically, chemically, ecologically distribution range. We analysed 64 specimens C. bellidiflora,...
In situ remediation is usually restricted by temperature, lack of substrate for reductive dechlorination (anaerobic respiration), the presence dehalogenating microorganisms, and specific bedrock conditions. this work, trichloroethene (TCE) degradation was studied a number methods, from physical–chemical analyses to molecular biological tools. The abundance changes in dechlorinating bacteria were monitored using real-time PCR. functional genes vcrA bvcA as well 16S rRNA representatives genera...
Abstract Cladonia luteoalba shows a specific pattern in chemical variability. Its chemotype coincides with that of the associated thalli. This has led to formation various hypotheses, but its true nature never been clarified. We collected C. Central Europe and Norway. The chemotypes were detected by TLC mycobionts photobionts identified Sanger sequencing ITS rDNA. Mycobiont cultures obtained Illumina metabarcoding fungal ITS1 rDNA region was performed targeting minor within None methods...
