Cyanochelin B: a cyanobacterium-produced siderophore with photolytic properties that negate iron monopolization in UV light Open
Siderophores are low-molecular-weight compounds excreted by microorganisms to acquire iron and possibly to monopolize iron resource to achieve competitive advantage over other strains, or to trade for other substrates in mutualistic relati…

Mining for Halogenated Metabolites of <i>Aetokthonos hydrillicola</i>, the “Eagle Killer” Cyanobacterium Open
The cyanobacterium Aetokthonos hydrillicola has recently become famous as the "eagle killer", producing the biindole alkaloid aetokthonotoxin (AETX), a pentabrominated neurotoxin causing the wildlife disease vacuolar myelinopathy. H…

Cyanochelin B: A siderophore produced by cyanobacterium <i>Leptolyngbya</i> sp. NIES-3755 with photolytic properties that negate iron monopolization in the UV-light Open
Siderophores are low-molecular-weight compounds excreted by microorganisms to facilitate iron uptake in times of its unavailability. Microbes may produce siderophores to monopolize iron and achieve competitive exclusion of other strains. A…

Revision of the pantropical genus Brasilonema (Nostocales, Cyanobacteria), with the description of 24 species new to science Open
Brasilonema was separated from Scytonema only in 2007 (Fiore et al. 2007). It possesses diagnostic morphological characteristics such as vacuole-like structures in older cells, frequent purple pigmentation of cells, rare false branching an…

Unveiling the ecological significance of algal mats and meadows: Insights into phosphorus cycling and primary production of benthic algae in post-mining lakes Open
Post-mining lakes are anthropogenic water bodies increasing globally due to mining suppression and recultivation. These lakes have ecological and socioeconomic significance, providing freshwater sources, wildlife habitats, and recreation p…

More than just an eagle killer: The freshwater cyanobacterium <i>Aetokthonos hydrillicola</i> produces highly toxic dolastatin derivatives Open
Cyanobacteria are infamous producers of toxins. While the toxic potential of planktonic cyanobacterial blooms is well documented, the ecosystem level effects of toxigenic benthic and epiphytic cyanobacteria are an understudied threat. The …

Alcobiosis, an algal-fungal association on the threshold of lichenisation Open
Alcobiosis, the symbiosis of algae and corticioid fungi, frequently occurs on bark and wood. Algae form a layer in or below fungal basidiomata reminiscent of the photobiont layer in lichens. Identities of algal and fungal partners were con…

Unsuspected findings about phylogeny and ultrastructure of the enigmatic cyanobacterium Microcrocis geminata resulted in its epitypification and novel placement in Geminocystaceae Open
The genus Microcrocis belongs to long ago established cyanobacterial taxa for which relevant data required for a modern taxonomic analysis remained unknown for a long time.In present study we proposed an epitype originating from a large na…

Polyphasic approach to a characteristic Ulva population from a limno-rheocrenic, mineral (chloride, sodium, sulphate) spring in the Siwa Oasis (Western Desert of Egypt) Open
An interesting population of ulvacean green algae was collected from a limno–rheocrenic, thermal, mineral (chloride, sodium, sulphate) spring known as “Ain Abu Sherouf” in the Siwa Oasis, the Western Desert of Egypt. A detailed combined in…

Highly divergent 16S rRNA sequences in ribosomal operons of Scytonema hyalinum (Cyanobacteria) Open
A highly divergent 16S rRNA gene was found in one of the five ribosomal operons present in a species complex currently circumscribed as Scytonema hyalinum (Nostocales, Cyanobacteria) using clone libraries. If 16S rRNA sequence macroheterog…

New and unusual species of cyanobacteria, diatoms and green algae, with a description of a new genus Ekerewekia gen. nov. (Chlorophyta) from the table mountain Churí-tepui, Chimantá Massif (Venezuela) Open
The unique character of biotas on table mountains (tepuis) is well documented for macroscopic organisms. However, much less is known about the microorganisms inhabiting these unusual and diverse biotopes. Previously, new algal and cyanobac…
