Fatty Acids in Lipids from Particulate Organic Matter in a Eutrophic Lake, Lake Nakanuma, Japan

Abstract

The depth profiles and seasonal abundance of fatty acids in lipids from the particulate organic matter in the eutrophic Lake Nakanuma, Japan, were closely related to both photosynthetic activity and the difltribution of phytoplankton. The changes in the relative proportions of the fatty acids suggest that their synthesis is directly related to the photosynthetic activity of phytoplankton.
