Do you have a bacterium that is a sulphur-concentrating obligate anaerobe?"

Although it is considered a obligate anaerobe, Cl.

It is an obligate anaerobe, meaning that oxygen is poisonous to the cells.

They are rod-shaped and obligate anaerobe.

Brachyspira pilosicoli is a Gram-negative, spiral-shaped, obligate anaerobe bacterium.

Bacteroides fragilis is a Gram-negative bacillus bacterium species, and an obligate anaerobe of the gut.

Two sub-types exist: facultative anaerobe and obligate anaerobe.

It is an aggregated coccus, obligate anaerobe, heterotrophic, archeon that grows 0.8-1.3 μm in diameter.

The identification of the obligate anaerobe Clostridium pasteurianum capable of fixing atmospheric nitrogen and living in legume root nodules.

Facultative anaerobe can tolerate anaerobic and aerobic condition; however, an obligate anaerobe would die in presence of even trace levels of oxygen.

Dichelobacter nodosus, formerly Bacteroides nodosus, is a Gram-negative, obligate anaerobe of the family Cardiobacteriaceae.

C. tetani is a rod-shaped, obligate anaerobe which stains Gram positive in fresh cultures; established cultures may stain Gram negative.

The spore-forming bacteria can again be divided based on their respiration: Bacillus is a facultative anaerobe, while Clostridium is an obligate anaerobe.

T. kodakarensis is an obligate anaerobe, and a heterotroph, growing rapidly on a variety of organic substrates in the presence of elemental sulfur, producing hydrogen sulfide gas.

"The chlorine-converting bug is an obligate anaerobe-" Kelvin said, then added for Boone's benefit, "-that means it has to live in an environment with no air in it."

However, there have been examples of poor manufacture (underprocessing) and poor hygiene allowing contamination of canned food by the obligate anaerobe Clostridium botulinum, which produces an acute toxin within the food, leading to severe illness or death.

He returned to St. Petersburg for the period 1891-1905, and headed the division of general microbiology of the Institute of Experimental Medicine; during this period, he identified the obligate anaerobe Clostridium pasteurianum, which is capable of fixing atmospheric nitrogen.
