Abstract
(English)
A fluorescence-chromatography cross-investigation on C-18 Sep-Pak extractable organig matter produced by a laboratory culture of Phaeodactylum tricornutum (SPE-POM)is presented. A comparison with the fluorescence and chromatographic characteristics of the Sep-Pak extractable dissolved marine organic matter (SPE-MOM)is also described.The results show that Phaeodactylum tricornutum excrets two main groups of fluorescent compounds consisting of protein material and flavins, which are very quickly degradated to simplier structures which can be considered a part of the starting reagents of humification reactions in the sea. Reverse phase high performance liquid chromatography (RP-HPLC) allowed two degradation products of riboflavin to be isolated.
