MANGROVE ACTINOMYCETES PROTIENS PDF

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.

Mangrove rare actinobacteria: taxonomy, natural compound, and discovery of bioactivity

Diverse mangrove actinomycetes as promising and productive sources are worth being explored and uncovered. Originally, this compound was isolated from the plant, Peganum harmala Zygophillaceae located in the Middle East, India, and North Acitnomycetes. A new compound named methyl hexadecanoic acid 2-acylglycerol 72 was discovered in Streptomyces sp. Introduction In the past few decades, repeated isolation of known natural products and a reduced hit-rate of novel compounds from heavily investigated terrestrial microorganisms have limited the development of new and effective drugs for treating ever increasing human diseases [ 1 actinomycetds.
