Lipopolysaccharides of the cyanobacterium Microcystis aeruginosa [PDF]

open access: yesEuropean Journal of Biochemistry, 1983
Lipopolysaccharides (LPS) of two isolates of Microcystis aeruginosa were extracted with phenol/water and purified. Cesium chloride gradient ultracentrifugation of these preparations yielded only one fraction. The LPS contained significant amounts of 3‐deoxy‐d‐manno‐octulosonic acid, glucose, 3‐deoxy sugars, glucosamine, fatty acids, fatty acid esters ...

Heterocyst differentiation in the cyanobacterium Mastigocladus laminosus [PDF]

open access: yesJournal of Bacteriology, 1984
The morphological and ultrastructural aspects of heterocyst differentiation in the branching, filamentous cyanobacterium Mastigocladus laminosus were examined with light and electron microscopy. The earliest differentiation stages involved cytoplasmic changes, including (i) rapid degradation of carboxysomes, (ii) degradation of polysaccharide granules,

Temporal variability of diazotroph community composition in the upwelling region off NW Iberia. [PDF]

open access: yes, 2019
Knowledge of the ecology of N2-fixing (diazotrophic) plankton is mainly limited to oligotrophic (sub)tropical oceans. However, diazotrophs are widely distributed and active throughout the global ocean.
