Kigalkree Methylpendolmycin, an indolactam from a Nocardiopsis sp. Mangrove rhizosphere soil and root Hainan, China. This article is an open access article distributed under the mangroce and conditions of the Creative Commons Attribution license http: The important physical features of the mangrove that aid their survival in the boundary zone between ocean and land are adaptations for mechanical fixation in loose soil, specialized dispersal mechanisms, breathing roots and air exchange devices, and specialized mechanisms for dealing with excess salt concentration Spalding et al.
The NGS technology is known to be costly for the assessment of huge numbers of environmental samples with high sequencing depths Zhou et al. Mangrove rare actinobacteria: taxonomy, natural compound, and discovery of bioactivity This article has been cited by other articles in PMC. However, the recent search for the novel compounds always lead to the rediscovery of known compounds from the same species Koehn and Carter, Even so, new species and genus in mangrove represent to a certain degree the uniqueness of prtoiens actinomycetes and indeed produce novel bioactive compounds or chemical scaffolds.
Ansa-macrolides Ding et al. The producer Streptomyces lusitanus XM52 was isolated from the rhizosphere of the mangrove plant Avicennia mariana from Fujian Province, China. From Monsoons to Microbes: As a result, there is a dramatic increase in demand to look for new pharmacological important compounds. Then Liu et al. Root of Avicennia marina collected at mangrove forest in Wengchang, Hainan province, China.
Natural Products from Mangrove Actinomycetes Actinomycetes populations in mangrove rhizosphere. Actinobacteria Under the domain Bacteria, the Actinobacteria is one of the most acfinomycetes phyla among the 30 major lineage including 5 subclasses www. The isolation of rare actinobacteria could definitely increase the chances of discovering potentially novel bioactive compounds, therefore it is vital to be equipped with better knowledge of their diversity and distribution in the environment; in order to facilitate the isolation of these strains using an efficient approach Hong et al.
As some Streptomyces strains from different environments produced the same types of compounds, possibly due to frequent genetic exchange between species Bredholt et al.
