Sample text

The selection of the topics presented is entirely personal, but I hope that the material covered is broad enough to provide a general introduction to the nature of the cyanobacteria, whose applied aspects form the subject of most chapters in this book. In an introductory chapter of similar nature my late friend Noel Carr (1999) wrote: . . my first response will be some kind of general disclaimer with respect to synoptic balance or indeed total accuracy . . The best that one can hope for is a personal, hopeful dispassionate, version of some of the developments and constraints that have happened in our own field .

1999). Trichodesmium blooms consist of long filaments that cluster to form aggregates of different morphologies. These aggregates can move great distances through the water column, their buoyancy being regulated by presence of gas vesicles (see below). It was previously hypothesized that the aggregates allowed interior cells to act as “heterocysts” (Carpenter and Price, 1976), but this does not appear to be the case. There are indications that nitrogenase is present in a subset of the cells in the trichome, termed “diazocytes” (Fredriksson and Bergmann, 1997).

The blue phycocyanin (absorption peak 620 nm), the red phycoerythrin (565 nm) and the comparatively rare phycoerythrocyanin (570 nm) are present in rods that emanate from the core. , 1993; Carr, 1999; Stal, 2007). 11 Certain species, notably strains of Oscillatoria and Phormidium, change their color as a function of the spectral properties of the light in which they are grown. ” It was first observed by Theodor Wilhelm Engelmann in 1883. When the organisms are illuminated with a spectrum of light, they assume, over the course of a day or two, a color complementary to that part of the spectrum in which they are growing.
