Selective feeding of bdelloid rotifers in river biofilms. [PDF]
PLoS ONE, 2013 In situ pigment contents of biofilm-dwelling bdelloid rotifers of the Garonne River (France) were measured by high performance liquid chromatography (HPLC) and compared with pigment composition of surrounding biofilm microphytobenthic communities.

Antitumor activity of hierridin B, a cyanobacterial secondary metabolite found in both filamentous and unicellular marine strains. [PDF]
PLoS ONE, 2013 Cyanobacteria are widely recognized as a valuable source of bioactive metabolites. The majority of such compounds have been isolated from so-called complex cyanobacteria, such as filamentous or colonial forms, which usually display a larger number of ...

EVIDENCE FOR INTERGENERIC TRANSFORMATION IN FILAMENTOUS, DIAZOTROPHIC CYANOBACTERIA [PDF]
New Phytologist, 1987 SummaryA clonal population of a mutant Nostoc muscorum, with the ability to assimilate azide as a fixed nitrogen source, was used as a source of donor DNA for transforming Anabaena doliolum from an azide‐sensitive to an azide‐assimilating phenotype. The donor DNA. transformed A.

Temperature-dependent effect of filamentous cyanobacteria on Daphnia magna life history traits
Journal of Limnology, 2011 Filamentous cyanobacteria are unsuitable food for Daphnia due to their poor manageability, poor nutritional value and, in some cases, toxicity. As the strength of harmful effects of cyanobacteria on filter-feeding zooplankton is temperature dependent ...

Natural transformation of the filamentous cyanobacterium Phormidium lacuna.
PLoS ONE, 2020 Research for biotechnological applications of cyanobacteria focuses on synthetic pathways and bioreactor design, while little effort is devoted to introduce new, promising organisms in the field. Applications are most often based on recombinant work, and

The multicellular nature of filamentous heterocyst-forming cyanobacteria [PDF]
FEMS Microbiology Reviews, 2016 Cyanobacteria carry out oxygenic photosynthesis, play a key role in the cycling of carbon and nitrogen in the biosphere, and have had a large impact on the evolution of life and the Earth itself. Many cyanobacterial strains exhibit a multicellular lifestyle, growing as filaments that can be hundreds of cells long and endowed with intercellular ...

mBio, 2016 Here we present the first genomic characterization of viruses infecting Nostoc, a genus of ecologically important cyanobacteria that are widespread in freshwater. Cyanophages A-1 and N-1 were isolated in the 1970s and infect Nostoc sp.

Cyanophycin mediates the accumulation and storage of fixed carbon in non-heterocystous filamentous cyanobacteria from coniform mats. [PDF]
PLoS ONE, 2014 Thin, filamentous, non-heterocystous, benthic cyanobacteria (Subsection III) from some marine, lacustrine and thermal environments aggregate into macroscopic cones and conical stromatolites.

Envelope structure of four gliding filamentous cyanobacteria [PDF]
Journal of Bacteriology, 1995 The cell walls of four gliding filamentous Oscillatoriaceae species comprising three different genera were studied by freeze substitution, freeze fracturing, and negative staining. In all species, the multilayered gram-negative cell wall is covered with a complex external double layer. The first layer is a tetragonal crystalline S-layer anchored on the
