Description
Gram-positiveGram-positive
Gram-positive bacteria are those that are stained dark blue or violet by Gram staining. This is in contrast to Gram-negative bacteria, which cannot retain the crystal violet stain, instead taking up the counterstain and appearing red or pink...

Acid-fast
Acid-fastness is a physical property of certain bacteria, specifically their resistance to decolorization by acids during staining procedures.Acid-fast organisms are difficult to characterize using standard microbiological techniques Acid-fastness is a physical property of certain bacteria,...

Colony characteristics
- ScotochromogenicScotochromogenicScotochromogenic bacteria develop pigment in the dark or in the light. Runyon Group II nontuberculous mycobacteria are examples but the term could apply to many other organisms....
colonies, production of a saffron yellow pigment on Middlebrook 7H10Middlebrook 7H10 AgarMiddlebrook 7H10 Agar is a solid growth medium specially used for culture of Mycobacterium, notably Mycobacterium tuberculosis. It has been reported that the 7H10 medium tends to grow fewer contaminants than the egg-based media commonly used for the cultivation of mycobacteria.- Composition :*...

at temperatures between 18°C and 28°C. - Capable of cooxidizing fluorantheneFluorantheneFluoranthene is a polycyclic aromatic hydrocarbon consisting of a naphthalene and a benzene unit connected by a five-membered ring. It is a member of the class of PAHs known as non-alternant PAHs because it has rings other than those with six carbon atoms. It is a structural isomer of the...
