Vampirovibrio chlorellavorus is a 0.6 μm pleomorphic coccus with a gram negative cell wall, [1] and is one of the few known predatory bacteria. [2] Unlike many bacteria, V. chlorellavorus is an obligate parasite, attaching to the cell wall of green algae of the genus Chlorella. [3]
The evolution of bacteria on a "Mega-Plate" petri dish A list of antibiotic resistant bacteria is provided below. These bacteria have shown antibiotic resistance (or antimicrobial resistance). Gram positive Clostridioides difficile Clostridioides difficile is a nosocomial pathogen that causes diarrheal disease worldwide. Diarrhea caused by C. difficile can be life-threatening. Infections are ...
Its hydrogen yield is lower than that of such strict anaerobes as Clostridia: strictly anaerobic bacteria produce a theoretical maximum of 4 mol H 2 /mol glucose, while such facultative anaerobic bacteria as K. aerogenes theoretically yield a maximum of 2 mol H 2 /mol glucose. [6] K. aerogenes may spoil maple sap and syrup. [7]
A tin of meat was exposed to a dose of radiation that was thought to kill all known forms of life, but the meat subsequently spoiled, and D. radiodurans was isolated. [1] The complete DNA sequence of D. radiodurans was published in 1999 by The Institute for Genomic Research. A detailed annotation and analysis of the genome appeared in 2001. [4]
The bacterium was discovered during the early 2010s by Olivier Gros from the University of the French Antilles at Pointe-à-Pitre, but initially it did not attract much attention as Gros thought his find to be a fungus; [4] it took Gros and other researchers five years to determine that it was a bacterium, and a few more years until Jean-Marie Volland, a graduate student supervised by Gros ...
Pathogenic bacteria are bacteria that can cause disease. [1] This article focuses on the bacteria that are pathogenic to humans. Most species of bacteria are harmless and many are beneficial but others can cause infectious diseases. The number of these pathogenic species in humans is estimated to be fewer than a hundred. [2]
C. botulinum is a Gram-positive, rod-shaped, spore-forming bacterium. [1] It is an obligate anaerobe, the organism survives in an environment that lacks oxygen.However, C. botulinum tolerates traces of oxygen due to the enzyme superoxide dismutase, which is an important antioxidant defense in nearly all cells exposed to oxygen. [7]
Bacteria (/ b æ k ˈ t ɪər i ə / ⓘ; sg.: bacterium) are ubiquitous, mostly free-living organisms often consisting of one biological cell. They constitute a large domain of prokaryotic microorganisms. Typically a few micrometres in length, bacteria were among the first life forms to appear on Earth, and are present in most of its habitats.
