چکیده
Maleic hydrazide (1, 2-dihydropyridazine-3, 6dione) is an organic plant growth regulator which has found use in such varied areas as prevention of sucker formation in tobacco, prevention of sprouting of some stored vegetables, and as a herbicide. In commercial application the diethanolamine salt (diethanolammonium maleic hydrazide or diethanolammonium-1 ,2-dihydropyridazine-3, 6-dione) is often used. Because of the nature of the use of maleic hydrazide, many workers have been concerned with its effects on soil microorganisms. Lembeck and Colmer (1957) found in their work with the herbicide and its components that some of their bacterial isolates were not only not harmed by field rates of application but could use the herbicide in their metabolism. One of these organisms, A Icaligenes faecalis, when growing in the presence of diethanolammonium maleic hydrazide, produced a gummy material which caused the medium to become quite viscous. Originally it was thought that this reaction was a characteristic response limited to the maleic hydrazide salt; later work, however, showed this not to be true. It was shown by Magee (1958) that the gum was a polysaccharide composed of glucose units. This report is concerned with gum formation by A. faecalis under different cultural conditions.

Background and Objective: Alcaligenes sp. is a non-fermentative Gram-negative bacillus, which causes nosocomial infections, including urinary tract infections, pneumonia, sepsis, and may be confused with Pseudomonas aeruginosa. Alcaligenes infections usually are not well identified and due to possible errors and similarities with Pseudomonas, their diagnosis with phenotypic tests is not suffici...

A bacterial strain (designated as Alcaligenes sp. MS-103) isolated from oil sample of the Aghajari oilfield in the south of Iran, was able to produce an effective extracellular lipopolysaccharide biosurfactant (1.2±0.05 g/l) on molasses as a sole carbon source. The highest surface tension reduction to level 20 mN/m was achieved by biosurfactant produced by cells grown on molasses under optimum ...

Alcaligenes fecalis BDB4 was isolated from crude oil-contaminated soil in India. The genome sequence of A. faecalis BDB4 revealed the presence of important genes required for polyaromatic hydrocarbon (PAH) metabolism and other associated functions, such as chemotaxis, membrane transport, and biofilm formation, giving insight into the complete PAH mineralization potential of this bacterium.
