Quantitative polymerase chain reaction method compared with traditional methods for Clostridium tyrobutyricum in grass-clover silage por Eklund, Madelene

“…C. tyrobutyricum is the most common type of bacteria to contaminate milk and cause late blown cheese caused by high spore counts in silage. The purpose of this thesis was to test a qPCR method to quantify C. tyrobutyricum in silage, by investigating potential differences in the clostridia spore estimate between the qPCR method, the MPN method and the plate count method. …”
