Cyanobacterium (Dermocarpa spp.). Magnification 5,335, transmission electron micrograph of a thin section of the cell showing internal cellular details, such as, thylakoids (photosynthetic membranes - green), phycobilisomes (blue), mesosomes (orange), nucleoid regions containing DNA (yellow), polyhedral bodies (purple), cell membrane and mucilaginous sheath (dark blue). This cyanobacterium (prokaryote) is a salt water, unicellular, endospore forming genus that reproduces by multiple fission producing motile baeocytes. Courtesy of Dennis Kunkel.
Stachybotrys spp. Fruiting structure with spores. Magnification 340, scanning electron microscopy. Often known as the toxic mold. Several strains of this fungus (S. atra, S. chartarum and S. alternans are synonymous). This fungus may produce a trichothecene mycotoxin - Satratoxin H - which is poisonous by inhalation. The toxins are present on the fungal spores. The toxins produced by this fungus will suppress the immune system affecting the lymphoid tissue and the bone marrow. The spores will die readily after release but the dead spores are still allergenic and toxigenic. Courtesy of Dennis Kunkel.

The bacterium Escherichia coli (E. coli for short) is crucial in modern biotechnology. Scientists use it to store DNA sequences from other organisms, to produce proteins and to test protein function.
Researchers analyzing the genomes of microorganisms living in shale oil and gas wells have found evidence of sustainable ecosystems taking hold there.
