Here, we present a comparative study addressing the composition of algal communities on sandstone substrata based upon the analysis of rRNA gene clone libraries from environmental samples and crude cultures. From a west-facing, shaded wall area of the mediaeval castle ruin Gleichen (Thuringia, Germany), sequences mainly related to the green algae Prasiococcus and Trebouxia (Trebouxiophyceae) were retrieved. A south-west-facing, sun-exposed wall area was mainly colonized by Apatococcus and a Phyllosiphon-related alga. Just a few species, in particular Stichococcus-related strains, were ubiquitous in both areas. Samples from a basement vault exposed to low irradiance exhibited Chlorophyceae like Chromochloris and Bracteacoccus. Thus, most green algae on the daylight-exposed walls were affiliated to Trebouxiophyceae, whereas Chlorophyceae were dominant in samples taken from the site kept under low irradiance. Accordingly, cyanobacterial communities were different: the sun-exposed area was dominated by Synechococcus-related organisms, while on the shaded wall area, cyanobacteria were almost absent. The filamentous Leptolyngbya dominated samples from the basement vault. Scanning electron microscopy revealed endolithic algal morphotypes (coccoid algae and diatoms) dominant in open pores between mineral particles. Here, the organisms may be also involved in biogenic weathering of stone."],["dc.identifier.doi","10.1111/1574-6941.12065"],["dc.identifier.isi","000317430200012"],["dc.identifier.pmid","23278436"],["dc.identifier.uri","https://resolver.sub.uni-goettingen.de/purl?gro-2/30101"],["dc.notes.status","zu prüfen"],["dc.notes.submitter","Najko"],["dc.publisher","Wiley-blackwell"],["dc.relation.issn","0168-6496"],["dc.title","Molecular diversity of phototrophic biofilms on building stone"],["dc.type","review"],["dc.type.internalPublication","yes"],["dc.type.peerReviewed","yes"],["dc.type.status","published"],["dspace.entity.type","Publication"]]

In the presented study, we focus on depth profiles of microbial colonization in sandstones with different porosity and overall durability. The sandstones were exposed to the environment for several years and were covered with a dense brown-greenish biofilm. Samples from the stone surface, from 0.5cm and from 3.0cm depths were taken under sterile conditions and subjected to analysis of microbial DNA (sequencing of 18S rRNA genes) and culturing experiments. A silica cemented Buntsandstein was just colonized at the stone surface, predominantly with algal and fungal microorganisms. Here, no environmental DNA could be isolated from depth profiles. From a calcitic Chirotheriensandstein with high pore size (shown by thin sections), environmental DNA from depths down to 3cm could be retrieved. Apart from filamentous fungi and algae, mosses clearly dominated the microbial community. Hence, moss rhizoids or protonemata must be abundant as endoliths inside the stone material. It is reasonable to assume that the rhizoids may contribute to an increase in pore size by active penetration of the clastic material, even though colonization of the surface by mosses may not be necessarily obvious. This feature may imply stronger impact of stone decay induced by endolithic growth of bryophytes than hitherto observed."],["dc.description.sponsorship","Deutsche Bundesstiftung Umwelt (DBU); DFG [FOR 571]"],["dc.identifier.doi","10.1080/01490451.2014.929762"],["dc.identifier.isi","000352349600015"],["dc.identifier.uri","https://resolver.sub.uni-goettingen.de/purl?gro-2/37632"],["dc.notes.status","zu prüfen"],["dc.notes.submitter","Najko"],["dc.publisher","Taylor & Francis Inc"],["dc.relation.issn","1521-0529"],["dc.relation.issn","0149-0451"],["dc.title","Depth profiles of microbial colonization in sandstones"],["dc.type","journal_article"],["dc.type.internalPublication","yes"],["dc.type.peerReviewed","yes"],["dc.type.status","published"],["dspace.entity.type","Publication"]]
