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.

In recent anoxic sediments, Mn(II)carbonate minerals (e.g. rhodochrosite, kutnahorite) derive mainly from the reduction of Mn(IV) compounds by anaerobic respiration. The formation of huge manganese-rich (carbonate) deposits requires effective manganese redox cycling in an oxygenated atmosphere. However, putative anaerobic pathways such as microbial nitrate-dependent manganese oxidation, anoxygenic photosynthesis and oxidation in ultraviolet light may facilitate manganese cycling even in an early Archean environment, without the availability of oxygen. In addition, manganese carbonates precipitate by microbially induced processes without change of the oxidation state, e.g. by pH shift. Hence, there are several ways how these minerals could have been formed biogenically and deposited in Precambrian sediments. We will summarize microbially induced manganese carbonate deposition in the presence and absence of atmospheric oxygen and we will make some considerations about the biogenic deposition of manganese carbonates in early Archean settings."],["dc.identifier.doi","10.1017/S1473550416000264"],["dc.identifier.eissn","1475-3006"],["dc.identifier.isi","000381033400006"],["dc.identifier.issn","1473-5504"],["dc.identifier.uri","https://resolver.sub.uni-goettingen.de/purl?gro-2/73384"],["dc.language.iso","en"],["dc.notes.intern","DOI Import GROB-354"],["dc.notes.status","zu prüfen"],["dc.notes.submitter","Najko"],["dc.relation.issn","1475-3006"],["dc.relation.issn","1473-5504"],["dc.title","Manganese carbonates as possible biogenic relics in Archean settings"],["dc.type","journal_article"],["dc.type.internalPublication","yes"],["dc.type.peerReviewed","yes"],["dspace.entity.type","Publication"]]

For this purpose, the isotopic composition of lipids (delta C-13) and bulk organic shell matrix (delta C-13, delta S-34, delta N-15) from shells of several thiotrophic, phototrophic, or non-symbiotic bivalves were compared (phototrophic: Fragum fragum, Fragum unedo, Tridacna maxima; thiotrophic: Codakia tigerina, Fimbria fimbriata, Anodontia sp.; non-symbiotic: Tapes dorsatus, Vasticardium vertebratum, Scutarcopagia sp.). Delta C-13 values of bulk organic shell matrices, most likely representing mainly original shell protein/chitin biomass, were depleted in thio-and phototrophic bivalves compared to non-symbiotic bivalves. As the bulk organic shell matrix also showed a major depletion of delta N-15 (down to -2.2 &) for thiotrophic bivalves, combined delta C-13 and delta N-15 values are useful to differentiate between thio-, phototrophic, and non-symbiotic lifestyles. However, the use of these isotopic signatures for the study of ancient bivalves is limited by the preservation of the bulk organic shell matrix in fossils. Substantial alteration was clearly shown by detailed microscopic analyses of fossil (late Pleistocene) T. maxima and Trachycardium lacunosum shell, demonstrating a severe loss of quantity and quality of bulk organic shell matrix with time. Likewise, the composition and delta C-13-values of lipids from empty shells indicated that a large part of these compounds derived from prokaryotic decomposers.

However, little is known about their tube as a potential niche for other chemosynthetic and non-chemosynthetic microorganisms. Analyses by scanning and transmission electron microscopy showed dense biofilms on the tube in Al Gacel MV and Anastasya MV specimens by prokaryotic cells. Methanotrophic bacteria were the most abundant forming these biofilms as further confirmed by 16S rRNA sequence analysis. Furthermore, elemental analyses with electron microscopy and EDX point to the progressive mineralization of the biofilm and the tube in absence of nutrients. Environmental bacterial and archaeal 16S rRNA sequence libraries revealed abundant microorganisms related to these siboglinid worms and variation in microbial communities among samples. We argue that these differences must be related to variance in seepage activity, as it is the main source of nutrients. Thus, the tube remarkably increases the microbial biomass related to the worms and needs to be incorporated as an important part of the worm’s microbiota.

Publications on the immunohistochemical identification of PrPSc in the tonsils and appendix in the incubation period of nvCJD indicate that new and more sensitive techniques for the detection of PrPSc in various tissues may be a valuable tool for early diagnosis in prion diseases. We developed a new and sensitive technique to detect PrPSc in formalin-fixed and paraffin-embedded tissue, the paraffin-embedded tissue blot (PET blot), and reinvestigated archival brain material from CJD as well as BSE and scrapie. In addition, C57/B16 mice experimentally infected with the ME7 strain were investigated sequentially during the incubation time to compare this new technique with conventional methodologies. The PET blot detects PrPSc in idiopathic (sporadic) and acquired prion diseases, even in cases with equivocal or negative immunohistochemistry, and is more sensitive than the conventional Western blot and histoblot techniques. The PET blot makes possible the detection of PrPSc during the incubation period long before the onset of clinical disease and in prion disease variants with very low levels of PrPSc. In mice experimentally infected with the ME7 strain, the PET blot detects PrPSc in the brain 30 days after intracerebral inoculation-145 days before the onset of clinical signs, Its anatomical resolution is superior to that of the histoblot technique. It may therefore be of particular interest in biopsy diagnosis.

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.

The present work is focused on the discrimination between biotic and abiotic processes driving carbonate precipitation in this lake, using hydrochemical, mineralogical and isotopic data. Hydrochemical analyses demonstrate that the lake is nearly 10-fold supersaturated with regard to aragonite and seasonally reaches hydromagnesite supersaturation. Microscopic observations depict organosedimentary laminated structures consisting of microbial communities and aragonitic precipitates, which are rather disseminated in pores than directly linked to microorganisms. Oxygen isotopic data indicate that authigenic carbonate crystallisation from evaporating water is the dominant precipitation process, further suggested by the absence of textural evidence of diagenetic processes. Conversely, the observed delta C-13 values reflect an influence of extracellular polymeric substances (EPS) on carbon fractionation during the precipitation process, due to the selective sequestration of C-12 in the biomass. The above considerations suggest that at lake Specchio di Venere the carbonate precipitation is mainly of inorganic nature, but a minor role played by biologically influenced processes in microbial mats is not excluded.
