This paper presents the alkaloids found in green, brown and red marine algae. Algal chemistry has interested many researchers in order to develop new drugs, as algae include compounds with functional groups which are characteristic from this particular source. Among these compounds, alkaloids present special interest because of their pharmacological activities. Alkaloid chemistry has been widel...

Marine organisms are rich source of structurally new and biologically active metabolites. There have been many reports of macro algae-derived compounds that possess a broad range of biological functions, such as antibiotic, antiviral, antioxidant, antiinflammatory, cytotoxic, and antimitotic activities. Bioactive components have been revealed in many marine algae. Marine algal compounds are pre...

Most marine pyrenomycetes are lignicolous, but some are epiphytic on marine phanerogims and algae. Meyers (1957) listed 30 species of algae known to be attacked by these fungi. A number of reports dealing with marine ascomycetes on algal hosts appeared before 1900, the most noteworthy being those of Winter (1887), and Jones (1898). Cotton (1908) described a pyrenomycete on Ascophyllum nodosum (...

Algae are a very large and diverse group of autotrophic organisms which ranges from unicellular to multicellular forms. They are primary producers which is a source of many nutrients and it has high protein content. The most complex marine forms are called seaweeds. Blue green algae ,red algae, green algae assigned higher contents of dietary fibres. Certain beverages are prepared from sea algae...

Marine red algae (Rhodophyta) are a rich source of bioactive halogenated natural products. The biogenesis of the cyclic halogenated terpene marine natural products, in particular, has attracted sustained interest in part because terpenes are the biogenic precursors of many bioactive metabolites. The first enzymatic asymmetric bromination and cyclization of a terpene, producing marine natural pr...

Bacteriol. 83:97-99. 1962-Homogenized preparations of 35 marine algae were tested for inhibitory activity against 6 pathogenic or opportunistically pathogenic fungi with saturated filter-paper discs on seeded Sabouraud agar plates; 11 of these preparations p...
