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.

The genome sequence of Salinispora revealed a great number of novel biosynthetic gene clusters, and based on the analysis; these findings confirms that this genus actinomycetew one of the important sources of novel drug-like molecules.


Even though Strepotomyces is the genus producing various types of natural compounds for medical and pharmaceutical purposes, rare actinobacteria isolated from mangrove have a wide range of metabolites with different biological activities. Toward a total synthesis of divergolide A; Synthesis of the amido hydroquinone core protins the CC15 fragment.

Natural Products from Mangrove Actinomycetes

This strain consists of 5, bp in size, which is approximately 3 Mbp smaller than the genome of Streptomyces Bull and Stach, Conclusion The discovery of novel species and novel natural compounds from the mangrove rare actinobacteria is becoming a popular and attractive approach. Actinomycetes from sediments in the Trondheim Fjord, Norway: Also the antibacterial activity from a combination of rifamycin S and the geometric isomer of rifamycin S from Micromonospora rifamycinica AM was higher than rifamycin SV.

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

Salinispora Salinispora is a genus within the family Micromonosporaceae that was isolated from marine sediment in Maldonado et al. It is apparent that the discovery of novel rare actinobacteria can be expected to provide new bioactive compounds Lazzarini et al. 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.
