All oxidase-negative bacteria fell into groups III and IV. Bacteria in group III had low but still measurable TMPD oxidase rates, the Qo2 values ranging from 3 to 33, whereas the bacteria found in group IV were inert and unable to oxidize TMPD. A grouping analysis allowed for the ...

It was shown that the oxidase-negative bacteria were more effective than the oxidase-positive ones in the production of humic substance, and in decreasing the carbohydrate content of the straw.doi:10.1007/BF00411012Sundman VSpringer-VerlagArchiv Für Mikrobiologie...

A particular problem for gram-negative bacteria is that at neutral pH the speciation of Fe(III) is complex as the cation is present either as insoluble polynuclear oxo/hydroxo-bridged complexes or as soluble organic chelates. Thus, Fe(III) is frequently presented to bacteria in a range of ...
2. in bacteriology, a reaction that depends on the presence of certain oxidases in some bacteria that catalyze the transport of electrons between electron donors in the bacteria and an oxidation reduction dye, such as tetramethyl-p-phenylenediamine; the dye is reduced to a blue or black color....
Analysis of the fatty acids showed that the isolates were rather homogeneous but the values of the guanine plus cytosine content of the DNA of the bacteria varied too much for any conclusion to be drawn on their taxonomic location. The strains examined exhibited several biochemical characters that...
coli is typical of that of Gram-negative bacteria, consisting of a lipid bilayer whose inner leaflet is made up largely of phospholipids and whose outer leaflet is made of lipopolysaccharide (LPS). Interspersed are several kinds of membrane proteins. One, the murein lipoprotein, is small (7.2 ...
