Marine Algae from Black Sea - Important Resources in the Pharmaceutical and Medical Research

Abstract

During the past years, it became obvious that the ecosystem presents a marine algae surpluses, which should be turned valuable in one way or another. The importance of the macrobenthic flora – algae and phanero-gammes – for the general productivity of the marine environment, especially in shallow waters, is becoming more and more obvious from the biological as well as from the economical point of view. The macrophytes also represent a particular life form. The benthic macroflora includes 33 species 4: 16 Chlorophyta, 10 Rhodophyta, 5 Phaeophyta, and 2 Phanerogama. The quantity of green algae (Chlorophyta) was higher in the Constanta – Eforie area, as red algae are predominant in the southern part of the littoral. Brown algae (Phaeophyta) were encountered in the Constanta city area (Punctaria) and in Vama-Veche (Cystoseira barbata). Yet, this fact indicates a slight amelioration of the marine ecosystem, after many years of eutrophication. The superior capitalisation of the marine biomass represents a highly important resource for the pharmaceutical industry, supplying raw material for the extraction of bioactive substances and various other substances, the purity of which is strongly connected to the state of the marine ecosystem.
