Abstract :

Byline: Yeonghee Ahn (1), You Jin Lee (2), Hyo-Seob Kim (2), Sunghoon Park (2) Keywords: coenzyme F; confocal microscopy; fluorescence; granular sludge; methanogen Abstract: Confocal, laser-scanning microscopy was applied to acquire coenzyme F.sub.420-based autofluorescence images of middle sections of sludge granules during start-up of a thermophilic reactor that were seeded with mesophilically-grown microorganisms of granular sludge. Digital images were analyzed to calculate weighted averages of autofluorescence. The values were related (r .sup.2=0.97) to specific methanogenic activities of granular sludge as the granules developed to steady state.
