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.

Natural Products from Mangrove Actinomycetes
The mangrove ecosystem is becoming a hot spot for natural product discovery and bioactivity survey. Currently, some Micromonospora from the mangrove environment has produced useful bioactive compounds for studies on drug discovery. Rare actinobacteria are always referred to as strains that are difficult to isolate and might correspond to the unmatched source of new natural metabolites Baltz, Marizomib, a proteasome inhibitor for pritiens seasons: This review is an attempt to consolidate and summarize the past and the latest studies on mangrove actinomycetes natural product discovery and to draw attention to their immense potential as novel and bioactive compounds for marine drugs discovery.
These high-throughput sequencing technologies have enabled researchers to discover the microbial diversity from different environments; and also enabled the parallel sequencing of multiple bioactive strains for the identification of secondary metabolites gene clusters through comparative genomics analysis.
This result was in line with other studies Cross, ; Jiang and Actinomycetew, ; Hatano, ; Ara et al.
