The polymerase chain reaction (PCR) is used widely to recover rRNA genes from naturally occurring communities for analysis of population constituents. We have found that this method can result in differential amplification of different rRNA genes. In particular, rDNAs of extremely thermophilic archaebacteria often cannot be amplified by the usual PCR methods. The addition of 5% (wt/vol) acetamide to a PCR mixture containing both archaebacterial and yeast DNA templates minimized nonspecific… CONTINUE READING
