Diatom, Chlorophyll auto-fluorescentAbstract
Red auto-fluorescence refers to the emission of fluorescent light when high energy UV light was shined to chlorophyll a molecule. This specific type of auto-fluorescence was present in diatoms, but the intensity of auto-fluorescence varies with species. This study evaluates the relative auto-fluorescence intensity for diatoms taken from Dapeng Bay, Shenzhen. The auto-fluorescence intensity in Biddulphia mobiliensis was relatively high probably due to lower photosynthetic efficiency with high level of chlorophyll a; Other species, such as Melosira sp. and Skeletonema sp. examined in this study demonstrated lower auto-fluorescence intensity as they probably have more efficient photosynthetic processes and possess less overall number of chloroplasts.
