The former ones are dominated by gram-positive bacteria, mainly actinobacteria, as well as by their filamentous forms (actinomycetes), whereas the latter ones are dominated by gram-negative bacteria. A common feature of invertebrate's complexes in nepheline sands is the low species diversity, small...
Microscope photographs of the most common filamentous cyanobacteria found onScarus spinusbite cores. Black arrows indicate cyanobacteria taxaCi: Long trichomes ofCalothrix(Nostocales) with intercalary heterocysts,Cb: ShortCalothrix(Nostocales) with only basal heterocysts,M:Mastigocoleus testarum(Nostocales)...
Fungi secrete an array of carbohydrate-active enzymes (CAZymes), reflecting their specialized habitat-related substrate utilization. Despite its importance for fitness, enzyme secretome composition is not used in fungal classification, since an overarchi
Main components of the boundstone facies. a Autochthonous micrite with calcimicrobres; b calcified filamentous biofilms of cyanobacteria (Cy); c Microtubus communis; d Baccanella floriformis (Bf); e Tubiphytes sp. (T); f Olangocoelia otti. a Sample LC27; b, d sample LC25; c sample ...
(Bulking) inability of sludge solids to separate from the liquid under quiescent conditions; under aerobic conditions may be associated with the growth of filamentous organisms, low DO, or high sludge loading rates; under anaerobic conditions, may be associated with attachment of gas bubbles to .....
The microbial laminae consist of fossilised neutrophilic filamentous iron-oxidising bacteria. These bacteria oxidised the Fe(II)-rich acidic groundwater upon meeting the marine water at an approximately neutral pH. The iron oxyhydroxide laminae were initially precipitated as amorphous iron oxhydroxides ...
The amorphous iron oxyhydroxides, obtained from active and inactive vents, commonly possess filamentous textures similar in appearance to sheaths and stalks excreted by the iron-oxidizing bacteria itLeptothrix /itand itGallionella; /ithowever, formless agglomerates are also common. Textural relationships...
a filamentous Fe-Si oxide layer,and an outer Fe-Mn oxide layer.Investigations based on SEM and EDS showed that neutrophilic Fe-oxidizing bacteria play an important role in the formation of this chimney,particularly in the outer two generations.In the first stage,the metabolic activity of the ...
The form, the size and the color of a fungal colony are the features which can characterize genera and species of fungi. Besides the individual properties of fungal cultures (such as the existence of circadian rhythms, the ability to produce metabolites
The central role of filamentous bacteria in the precipitation of iron in acid mine drainage environments,[12] subterranean environments[13] and acidic surface hot springs[14] is well known. Fortin and Ferris[15, 16] discussed the capability of bacteria to provide nucleation sites favorable for ...
