PDF | Marine actinomycetes were isolated from sediment samples collected from of eight mangrove species of Pitchavaram mangrove ecosystem. Abstract: Mangroves are woody plants located in tropical and subtropical intertidal coastal regions. Driven by the discovery of novel natural products from. We conclude that actinomycetes isolated from mangrove habitats are a Similarly, potent and selective protein tyrosine phosphatase 1B.

They are all proven to have valuable sources of potential metabolites and besides Streptomyces ; they have proven to be valuable sources of potentially useful bioactive metabolites. Due to its properties of high salinity, strong winds, extreme tides, high temperature, anaerobic soils, and muddiness; little is known about the bacterial community living in the mangrove especially of Actinobacteria with the potential to produce bioactive metabolites.

Natural Products from Mangrove Actinomycetes
Nocardiopsis alba strain isolated from honeybee guts contains 5, bp with a GC content of Even though soils and water are their major habitat, they are also isolated from different environments such as the deep ocean, desert, mangroves, plants, caves, volcanic rocks, and stones Groth et al. Mangroves are woody plants located in tropical and subtropical intertidal coastal actinoymcetes.
Till the time of writing this paper, 24 genera of 11 families and 8 suborders under the actinomycetale have been reported from mangrove, among which 3 are new genera, and 31 are new species.
Obviously, the study on mangrove actinomycetes and their secondary metabolites is just beginning and mangrove actinomycetes require urgent exploitation as a valuable source of natural actinomyceges. Problems and countermeasure on development of pharmaceuticals from actinobacteria resource.

Actinobacteria for marine drug discovery isolated from mangrove soils and plants in China. Actinobacteria can be divided into two groups namely, Streptomyces and non- streptomyces or also known as rare actinobacteria.
Under the domain Bacteria, the Actinobacteria is one of the most distributed phyla among the 30 major lineage including 5 subclasses www. Compound 69 was protirns to be the first bacterial agarofuran, while compounds 67 and 68 actinomhcetes hydroperoxide groups were also unusual.
