Front 1

Escherichia coli

Back 1

The 'classic', gram-negative, facultative anaerobe, mixed acid fermenter, it is a genetic workhorse, opportunistic pathogen, and indicator of fecal contamination.

Front 2

Rhizobium meliloti

Back 2

This gram-negative aerobic rod, is a principle symbiotic nitrogen fixer, that creates a micro-anaerobic environment for nitrogenase to work, and also metabolizes mannitol.

Front 3

Rhodobacter sphaeroides

Back 3

Dr. Steiner's favorite bacterium, it is a facultative photoheterotroph, belonging to the purple non-sulfur bacteria, which used to be called Rhodopseudomonas.

Front 4

Serratia marcescens

Back 4

This gram-negative bacterium, initially considered harmless, produces a 'brick-red' pigment, prodigiosin, and is a primary cause of opportunistic, nosocomial infections.

Front 5

Caulobacter crescentus

Back 5

This dimorphic, gram-negative, bacillus shaped baceterium lives in nutrient depleted environments. It displays asymmetric cell division that alternates between a 'stalk' cell and a flagellated 'swarmer' cell.

Front 6

Bdellovibrio bacteriovorus

Back 6

This bacterial 'predator' moves extremely fast ("Ramming speeds!") and parasitizes other bacteria in order to reproduce.

Front 7

Clostridium botulinum

Back 7

This gram-positive, endospore-forming rod, soil bacterium, causes a flaccid-type of paralysis, and is often spread via eating undercooked/prepared food.

Front 8

Beggiatoa sp.

Back 8

Winogradsky worked with/discovered these "colorless, sulfur bacteria" that are gram-negative, extremely long filaments, that grow in high sulfur-containing springs.

Front 9

Pseudomonas aeruginosa

Back 9

This ubiquitous, gram-negative rod, obligate anaerobe, with a single polar flagellum, is highly resistant to antibiotics, and produces a variety of pigments and toxins.
