Molecular Biology Method in Microorganism Ecology Research Application

Because of the difficulty associated with traditional isolating and culturing bacteria,but the molecular techniques based on culture-independent techniques,extract directly the variable genomic DNA from microbial samples and then analysis the genetic information,by the amplification of polymeric chain reaction(PCR) nucleic acid hybridizerRNA sequence and other methods.At present,these molecular techniques have opened up the new way and been widely used in the research of microbial ecology.
