Molecular techniques in rumen biotechnology: A review

This review analyses the use of molecular techniques in rumen microbial identification. The use of regular methods like roll tube and most probable number resulted in under estimation of rumen microbial growth. So molecular biology acts as an advanced tool for rumen microbial culture and identification of various new species. These techniques give complete descriptions of individual ruminal populations. Use of molecular techniques like PCR, DDGE and FISH, which also pave pathway for genetic manipulation of rumen microbes in the field of rumen manipulation. So the combination of traditional and molecular assays gives accurate and satisfactory results.
