Cyanophyceae (blue-green algae) are algal-like bacteria with photosynthetic capabilities that can contaminate surface water supplies mostly during warm summer months. The toxic component is microcystin, which gives the water a moldy, musty, grassy, or septic-tank odor.

Why Cyanophyceae is called cyanobacteria?

Cyanobacteria /saɪˌænoʊbækˈtɪəriə/, also known as Cyanophyta, are a phylum of Gram-negative bacteria that obtain energy via photosynthesis. The name cyanobacteria comes from their color (Greek: κυανός, romanized: kyanós, lit.

Why is cyanobacteria green?

Cyanobacteria may live as single cells or colonies that create filaments, spheres, or irregular globs. The distinctive blue-green color comes from a pigment used to capture sunlight called 'phycocyanin,' although cyanobacteria can be many colors (see “I see something green in the water.
