Escherichia Coli
''Escherichia coli'' (),Wells, J. C. (2000) Longman Pronunciation Dictionary. Harlow [England], Pearson Education Ltd. also known as ''E. coli'' (), is a Gram-negative bacteria, Gram-negative, Facultative anaerobic organism, facultative anaerobic, Bacillus (shape), rod-shaped, coliform bacteria, coliform bacterium of the genus ''Escherichia'' that is commonly found in the lower intestine of warm-blooded organisms. Most ''E. coli'' Strain (biology), strains are harmless, but some serotypes (Enteropathogenic Escherichia coli, EPEC, Enterotoxigenic Escherichia coli, ETEC etc.) can cause serious Foodborne illness, food poisoning in their hosts, and are occasionally responsible for food contamination incidents that prompt product recalls. The harmless strains are part of the normal Gut microbiota, microbiota of the gut, and can benefit their hosts by producing Vitamin K, vitamin K2, and preventing colonisation of the intestine with pathogenic bacteria, having a Mutualism (biology), ...

Azomonas Macrocytogenes
''Azomonas'' species are typically motile, oval to spherical, and secrete large quantities of Slime layer, capsular slime. They are distinguished from ''Azotobacter'' by their inability to form cysts, but like ''Azotobacter'', they can biologically fix nitrogen under aerobic conditions (diazotrophs). Bacteria of the genus ''Azomonas'' are known to form intracellular inclusions of polyhydroxyalkanoates under certain environmental conditions (e.g. lack of elements such as phosphorus, nitrogen, or oxygen combined with an excessive supply of carbon sources). Etymology The name ''Azomonas'' derives from: : New Latin noun ''azotum'' [from Fr. noun ''azote'' (from Ancient Greek language, Greek prep. ά, ''a'', not; Ancient Greek language, Greek noun ζωή, ''zōē'', life; Greek language, Greek noun άζωη, ''azōē'', not sustaining life)], nitrogen; New Latin ''azo''-, pertaining to nitrogen; Latin -monas, ''monas'' (μονάς), nominally meaning "a unit", but in effect meaning ...

Bacillus Medusa
''Bacillus'' (Latin "stick") is a genus of Gram-positive, rod-shaped bacteria, a member of the phylum ''Firmicutes'', with 266 named species. The term is also used to describe the shape (rod) of certain bacteria; and the plural ''Bacilli'' is the name of the class (biology), class of bacteria to which this genus belongs. ''Bacillus'' species can be either obligate aerobes: oxygen dependent; or facultative anaerobes: having the ability to continue living in the absence of oxygen. Cultured ''Bacillus'' species test positive for the enzyme catalase if oxygen has been used or is present. ''Bacillus'' can reduce themselves to oval endospores and can remain in this dormant state for years. The endospore of one species from Morocco is reported to have survived being heated to 420 °C. Endospore formation is usually triggered by a lack of nutrients: the bacterium divides within its cell wall, and one side then engulfs the other. They are not true spores (i.e., not an offspring). ...

Bacillus Weihenstephanensis
''Bacillus mycoides'' is a bacterium of the genus ''Bacillus''. Like other ''Bacillus'' species, ''B. mycoides'' is Gram-positive bacteria, Gram positive, bacillus (shape), rod-shaped, and forms endospore, spores. ''B. mycoides'' is distinguished from other ''Bacillus'' species by its unusual growth on agar plates, where it forms expansive hairy colonies with characteristic swirls. Description ''B. mycoides'' are rod-shaped cells about 1 micron across and 3 to 5 microns long. When growing, they either grow as single cells or form loosely connected chains of cells. They are not motile. ''B. mycoides'' can survive facultative anaerobe, with or without oxygen and grows at temperatures ranging from 10–15 °C to 35–40 °C. ''B. mycoides'' is distinguished from a number of other ''Bacillus'' species in the unusual morphology of the colonies it forms when grown on agar plates. ''B. mycoides'' forms white opaque colonies that are characteristically hairy in appearance (often ...

Bacillus Thuringiensis
''Bacillus thuringiensis'' (or Bt) is a Gram-positive bacteria, Gram-positive, soil-dwelling bacterium, commonly used as a biological pesticide. ''B. thuringiensis'' also occurs naturally in the gut of caterpillars of various types of moths and butterfly, butterflies, as well on leaf surfaces, aquatic environments, animal feces, insect-rich environments, and flour mills and grain-storage facilities. It has also been observed to parasitize other moths such as ''Cadra calidella''—in laboratory experiments working with ''C. calidella'', many of the moths were diseased due to this parasite. During sporulation, many Bt strains produce crystal proteins (proteinaceous inclusions), called Delta endotoxin, δ-endotoxins, that have Insecticide, insecticidal action. This has led to their use as insecticides, and more recently to genetically modified crops using Bt genes, such as Genetically modified maize#Bt corn, Bt corn. Many crystal-producing Bt strain (biology), strains, though, do no ...
