All isolates were identified by classical approach by means of morphological, physiological and biochemical characterization. Published online May 2.
Xiamycin, a pentacyclic indolosesquiterpene with selective anti-HIV activity from a bacterial mangrove endophyte. Research Journal of Environmental Sciences; 1 4: A new macrocyclic dilactone 49 named as JBIR with potential anti-MPM malignant pleural kangrove activity was obtained from Promicromonospora sp.
This producer strain was isolated from a mangrove plant Acanthus illicifolius root in Hainan, China and compound 11 was proved to have no antivirus effects on H1N1. Diversity and biological activity.
Mangrove Actinomycetes as the Source of Ligninolytic Enzymes
The corresponding chemical structure is shown in Figure 9. Streptomyces has the mangrive advantage in the ability to produce bioactive compounds as well as isolation quantity [ 25 ]. In this review, we summarize the vast majority of studies about mangrove actinomycetes natural products and pharmacological activity and attempt to uncover the value of mangrove actinomycetes as an important source of novel and bioactive compounds which could become new and effective marine drugs.
Reaction was stopped by boiling waterbath for 15 minutes.
Natural Products from Mangrove Actinomycetes
Toward a total synthesis of divergolide A; Synthesis of the amido hydroquinone core and the CC15 fragment. Three new 2-pyranone derivatives from mangrove endophytic actinomycete strain Nocardiopsis sp. Compound 69 was believed to be the first bacterial agarofuran, while compounds 67 and 68 with hydroperoxide groups were also actinimycetes.
An extracellular protease with [3] Das, S.
Germacrane-Type Sesquiterpenes Guan et al. Abstract Mangroves are woody plants located in tropical and subtropical intertidal coastal regions.
Plates were incubated for days at suitable temperature. In addition, the ability of selective Streptomyces isolates producing important enzymes such as amylase, protease, lipases, esterase and gelatinase were screened for industrial application. Strain 1 ferments all sugars except Whatman filter paper no. October 07, [Advance Publication] Released: App Env Microbiol ; Streptocarbazoles A 7 and B 8 were obtained from Streptomyces sp.

Natural Products from Mangrove Actinomycetes
Screening of marine actinomycetes isolated from the Bay of Bengal, India for antimicrobial activity and industrial enzymes. Other Benzene Derivative A novel nitrogenous compound named as p -tolylaminopropanoate 33 was produced by Streptomyces sp.
The Cellulase producing positive strain 4 days. The corresponding chemical structure is shown in Actiinomycetes Experiments in Microbiology, Plant pathology and Biotechnology. Likewise, previous findings also proved the production of enzymes from marine actinomycetes[34, 35]. Hence, the present data state that extremely various amounts of top valued enzymes were screened from numerous Streptomyces species isolated from mangrove environment.
Fungichromin B showed nematicidal activity against 2-stage juveniles of M.
Compound 38 was regarded as the first natural antimycin which has an 8- O -acetyl side chain. References Census Commission of India. Actinomycetes from sediments in the Trondhein Fjrod, Norway: The group of genus present in soil sample varied from one region to others.
It has been observed that the genus Streptomyces among mangrove actinomycetes as natural product producers is the richest source followed by the genus Micromonospora. Diverse mangrove actinomycetes as promising and productive sources are worth being explored and uncovered. Recently, the first cloning and characterization of an indolocarbazole gene cluster isolated from Streptomyces sanyensis FMA was reported and indolocarbazole biosynthesis was confirmed by gene inactivation and heterologous expression in Streptomyces coelicolor M [ 32 ].
Bacterial synthesis of diverse indole terpene alkaloids by an unparalleled cyclization sequence. Currently, increasing number of investigation has been done to identify ecological factors deciding for active compounds of soil actinomycetes in the estuarine mangrove ecosystem [10].
