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...

Algae are a common component of freshwater ecosystems. The presence and abundance of these organisms has often been used as an indicator of water quality. In addition, algae such as Enteromorpha are able to accumulate pollutants, and have been used to monitor toxic trace metal pollution in aquatic environments [l]. In marine algae, heavy metal pollution has been shown to affect acyl-lipid compo...

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...

Abstract Alginates are natural polysaccharides that extracted from brown seaweed varieties and it is widely used for their rheological properties. The main step in the extraction protocol of sodium alginate alkaline extraction. Sodium was produced by dipping 1% formaldehyde 2.5% carbonate solution properties were studied following standard methods. amount yield 31.7% Sargassum wightii . moistur...
