Analysis method of intracellular iron accumulated in phytoplankton

Abstract

A colorimetric method for the assessment of iron accumulated in the cells of phytoplankton utilizing potassium ferrocyanide was developed. Two experiences with Phaeodactylum tricornutum and Chlorella sp. were carried out: the first one, on uptake of the iron relatively to the age of the culture: the second one, on the iron uptake by the cells, relatively to different concentrations of the chelator EDTA.

Effects of varying concentrations of certain major and minor nutrients on the interaction between a blue-green alga and a diatom

“…There have also been numerous studies of the intracellular iron concentrations in several different phyla, with the concentrations being in the yg*l ~ range (Eyster, 1978;Gerloff and Skoog, 1957;Jurajda, 1974;Udel'nova e^ , 1974;Walker, 1954). Paredes and Schmidt (1977) noted that a Chlorella sp.…”
