Pectinatus cells are nonspore-forming, slightly curved helical rods, 0.4-1.0 by 2-50 pm or more, with rounded ends. They typically occur singly, in pairs or rarely in short chains. In older cultures elongated snake-like cells and various round cell formations can be seen (Haikara Juvonen, 2009). A distinctive feature of the Pectinatus... 

Detailed infonnation regarding strictly anaerobic beer-spoilage bacteria can be found from the reviews of Haikara and Helander (2006), Haikara and Juvonen (2009), Marchandin et al. (2009) and Suzuki (2011). Comprehensive information regarding lipolysaccahrides of Pectinatus can be found from the review of Helander et al. (2004). Detection and identification methods for these organisms have been described in a doctoral thesis by Juvonen (2009).
