Research Abstract

Laboratory incubation experiments were carried out to evaluate the effect of benthic microalgal photosynthesis on microbial loop in intertidal flat ecosystems. The results showed that the decomposition of long chain fatty acids, which are comparatively refractory components in sediment organic matter, was promoted resulting from benthic microalgal photosynthesis. Furthermore, the stable isotope ratios of not only bacterial fatty acid but also diatom fatty acid were decreased clearly. Therefore, it was considered that benthic microalgal photosynthesis enhanced detritus food chain.
