Abstract

Author(s): K.Vijaya Bhaskar, A.Dayanand

A total of 16 actinomycetes were isolated from vegetative soil samples of Nallamala forest and screened for their efficiency for the production of vitamin B12.Among the 16 actinomycetes, Streptomyces DVB1 (1.328g/ ml) and StreptomycesDVB11 (1.217g/ml) yielded higher titers of vitamin B12. In addition to this, various animals’ fecal samples were screened and found highest content of vitamin B12 in tiger feceswith 1.057g/mg of fecal matter.
