coliform ferment lactose and are non pathogenic, non-coliform do not ferment lactose and are pathogenic (true pathogens)
90% to 100% of Enterobacter aerogenes strains can ferment glucose, sucrose, and lactose. The same percentage of strains produce gas as a byproduct of that fermentation.
Because bacillus cereus is a Gram-positive, spore-forming, and rod-shaped, it\'s only able to ferment glucose.
Citrobacter freundii complex refers to 8 related species of bacteria from the Genus Citrobacter, including Citrobacter braaki, Citrobacter freundii, Citrobacter gillenii, Citrobacter murliniae, Citrobacter rodenticum, Citrobacter sedlakii and Citrobacter werkmenii. These species all have similar phenotypic and genotypic characteristics, and in most cases cannot be reliably identified using the standard phenotypic methods employed in the laboratory. Therefore the identification for any one of the above species is most accurately reported as "Citrobacter freundii complex" Please see the article entitled "What's in a Name? The Genus Citrobacter" in the related web link. The Genus Citrobacter are part of the family Enterobacteriaceae, which are gram negative enteric (found in the intestinal tract) organisms.
Colorless, it doesnt ferment lactose.
they are non-sporing gram negative rods
lactose fermenter
No Proteus Vulgaris does not ferment lactose
Yes, Citrobacter freundii can metabolize lactose or citrate as a carbon source.
Yes it does.
yes, it does
coliform ferment lactose and are non pathogenic, non-coliform do not ferment lactose and are pathogenic (true pathogens)
no, it shows negative for lactose fermentation on MacConkey's agar
Fecal coliforms have the ability to ferment lactose at 44C +/- 0.05C while regular coliforms ferment lactose at 35C-37C
these are those bacteria which are not able to ferment lactose sugar hence are called non lactose fermenting or negative lactose fermenting organisms.
No, it doesn't. After performing the Lactose fermentation test, the isolated colonies will turn yellow meaning that the test was negative.
Yes. Therefore it grows on CLED media together with other gram negative organisms so you would see yellow colonies.
