It can be used in media employed for cultivation of fastidious organisms like Brucella, Mycoplasma, Pneumococci,
Gonococci, Meningococci, Actinomycetes, fungi, etc. and antibiotic sensitivity test. It can also be used in large scale
cultivation of microorganisms for the preparation of vaccines and for preparation of Blood Agar Bases, HiVeg (MV073,
MV834) .
