Abstract
A process using polymerize chain reaction (PCR) technology is described for the detection of spore forming bacteria in paper products and paper manufacturing streams and additives. Disclosed and claimed are novel nucleotide primers which specifically amplify sporulation genes common to spore forming bacteria. These primers produce gene fragments diagnostic for the presence of spore forming bacteria.
