Modified Multiplex PCR Methods for Comprehensive Detection of Pectinatus and Beer-Spoilage Cocci

Specific PCR primers were designed based on the 16S rRNA genes of recently proposed beer-spoilage species, Pectinatus haikarae, Megasphaera sueciensis, and M. paucivorans, and two sets of our previously reported multiplex PCR methods for Pectinatus spp. and beer-spoilage cocci were reconstructed. Each modified multiplex PCR method was found specifically to detect beer-spoilage species of Pectinatus and cocci, including new species.
