R. Thar et al., Fiber-optic fluorometer for microscale mapping of photosynthetic pigments in microbial communities, APPL ENVIR, 67(6), 2001, pp. 2823-2828
Microscale fluorescence measurements were performed in photosynthetic biofi
lms at a spatial resolution of 100 to 200 mum with a new fiber-optic fluoro
meter which allowed four different excitation and emission wavelengths and
was configured for measuring phycobiliproteins, chlorophylls, and bacterioc
hlorophylls. We present details of the measuring system and describe exampl
es of applications in different microbial communities.
