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

The NGS technologies enabled the production of results in a rapid, low-cost and reliable manner compared to actinomycetez approaches. The first reported compound from mangrove actinomycetes was the novel chalcomycin B 51 isolated from the culture broth of a marine Streptomyces sp.

Antibacterial agents from actinomycetes- a review. The mangrove forests are among the world’s most productive ecosystems which improves coastal water, produces commercial forest products, supports coastal fisheries, and protects coastlines. The mangrove ecosystem is among the world’s most productive environment, and it is a huge unexplored source of Actinobacteria with a high potential to produce active secondary metabolites Hong et al. This valuable microbial community produces different types of fascinating mangrvoe structurally complex natural products with biological activity.
