The plate assay, using guaiacol as substrate, had been identified as an effective method for the screening of ligninolytic actinomycetes. Journal of Marine Drugs 6, The fungal test organisms include Rhizopus, Whitish grey Yellowish white Reddish purple colour Aspergillus niger, Penicillium, Fusarium oxysporum and Neurospora crassa were aseptically inoculated using sterile cotton swab on Potato dextrose agar plates.
Antibacterial activity of some actinomycetes isolated from farming soil of turkey. This ecosystem is categorized by periodic tidal flooding which makes environmental factors such as salinity and nutrient availability extremely variable, resulting in unique and precise characteristic .
Notably, majgrove family of eudesmanes are secondary metabolites mainly from plants. Improvement of an isolation medium for actinomycetes.
Natural Products from Mangrove Actinomycetes
New azalomycin F analogs from mangrove Streptomyces sp. JBIR 32 was isolated from Streptomyces sp. These three new compounds have been proved to have strong antimicrobial activities against several bacteria, including methicillin-resistant Staphylococcus aureus and vancomycin-resistant Enterococcus faecalis.
The structures of indole alkaloids 2 — 9. Antimicrobial compounds from enzymfs plants: Mangroves, Actinomycetes, Diversity, StreptomycesEnzyme sources. Moreover, due to quick doubling time of microbes with special features than plants and animals, microbial fermentation process may possibly meet the current market demand for industrial enzyme .
More than species of mangrove endophytic fungi were isolated and natural products from them showed potential anti-microbial and actinomucetes activity [ 13 ]. All isolates were identified by classical approach by means of morphological, physiological and biochemical characterization. Macroscopic observation of numerous Streptomyces species The group of genus present in soil sample varied from one region to others.
Average Zone of Clearance mm. Bioactive compounds from marine bacteria and fungi. Ramesh S, Mathivanan N. A simple method for the detection of lipolytic activity of microorganisms and some observations on the influence of the contact between cells and fatty substracts.
Plant Pathology Journal 16 4: Soil samples were collected at a depth of cm from the land to the marine. Am Soc Microbiol Washington ; Streptocarbazoles, novel staurosporine analogs with unprecedented cyclic N -glycosidic linkages between 1,3-carbon atoms of the glycosyl moiety and two indole nitrogen atoms of the indolocarbazole core were other promising compounds isolated from mangrove actinomycetes.
In addition, Wu et al.
Mangrove Actinomycetes as the Source of Ligninolytic Enzymes
It is worth noting that the rare derivatives of compound 35 were isolated from a fungi previously but this is the first time the same type of novel compounds have been obtained from an actinomycete. Actinomycetrs zones around the L- asparaginase obtained through primary screening was inoculated in 50 mL producing colonies were observed.
Applied and Environmental Microbiology; Then Potts et al. A new compound butremycin 48 was isolated from Micromonospora sp. The occurrence of bioactive Micromonospora magnrove aquatic habitats of the sunshine coast in australia.
Natural Products from Mangrove Actinomycetes
They are heterotrophic, aerobic activities by isolated strains. Fenical W, Jensen PR. Alkaloids and sesquiterpenes are the main secondary metabolites of the genus Micromonospora.
Using sterile cork borer, bores were formed in each plate inoculated with test fungus and bacteria. Flavones A new di- O -prenylated flavone 73 was obtained from Streptomyces sp. The structures of other alkaloids 20 — The soil samples were collected from different region of dense muthupet mangrove forest. Two new macrocyclic lactones were identified as azalomycin F4a 2-ethylpentyl ester 52 and azalomycin F5a 2-ethylpentyl ester 53 by Yuan et al.
Streptocarbazoles A and B, two novel indolocarbazoles from the marine-derived actinomycete strain Streptomyces sp. Microbial enzymes formed by fermentation technique can simply be scale up. Afr J Biotechol ;3 9: October 07, [Advance Publication] Released: The producer Streptomyces lusitanus XM52 was isolated from the rhizosphere of the mangrove plant Avicennia mariana from Fujian Province, China.
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 enzymed Streptomyces coelicolor M [ 32 ]. Hensyl WR ededitor Alkaloids are the main natural products of two novel genus Jishengella and Salinispora and therein salinosporamides with specific structures have received significant attention.
