During the last 5 years a number of scientific reports have
been published that demonstrate the value of molecular
techniques in the circumscription of microbial populations in
the environment. The needs for genetic characterization has
been called for when it became obvious that traditional
phenotype based techniques failed to detect the full diversity
of bacterial types and to isolate the majority of organisms
present in a given sample, e.g. it has been speculated
that the percentage of organisms discovered in the environment
does not exceed 20%(1). Besides the application of DNA
hybridization, most modern studies are based on information of
rRNA and rRNA genes, molecules that have intensively been
dealt with during the last two decades.
