32) Which of the following bacterial genera is useful for sewage treatment? spirochete.,
What is the primary stain used in the Schaeffer Fulton staining method?
In the Schaeffer-Fulton`s method, a primary stain-malachite green is forced into the spore by steaming the bacterial emulsion. Malachite green is water soluble and has a low affinity for cellular material, so vegetative cells may be decolourized with water. Vegetative cells are then counterstained with safranin.
Which of the following genera is an anaerobic Gram-negative rod?
At present there are over two dozen genera of Gram-negative anaerobic bacilli. In most clinical infections, only the genera Bacteroides, Prevotella, and Fusobacterium need be considered. These genera are prevalent in the body as members of the normal flora (Fig.

Which of the following bacterial genera plays an important role in environmental nitrogen cycles quizlet?
Which of the following bacterial genera plays an important role in environmental nitrogen cycles? in the phylum Firmicutes and include Clostridia and Mycoplasma.
Which bacterial genera plays an important role in environmental nitrogen cycles?
The most prominent of these bacteria belong to the genus Nitrobacter. Together, ammonium oxidation and nitrite oxidation are referred to as nitrification. The net effect of nitrification is removal of ammonia and production of nitrate (NO3−). Denitrification produces nitrogen gas (N2) from inorganic nitrogen compounds.
