Produce biologically active secondary metabolites

The sea is a unique ecosystem for finding secondary metabolites from marine microorganisms. Many compounds produced by marine microorganisms with antibacterial activity have been applied in life. Furthermore, microorganisms are renewable raw materials and media for drug production, thus crucial for sustainable development in our life.

Plant growth promoting rhizo-bacteria (PGPR) affect plant growth by producing and releasing secondary metabolites (plant growth regulators/phytohormones/biologically active substances), facilitating the availability and uptake of certain nutrients from the root environment and inhibiting plant pathogenic organisms in the rhizosphere. At the same time, plants produce root exudates containing e.g. sugars, amino acids, organic acids, vitamins, enzymes and organic or inorganic ions.

Diabetes mellitus is a metabolic disorder characterized by hyperglycemia and alterations in carbohydrate, fat and protein metabolisms. Diabetes is associated with absolute or relative deficiencies in insulin secretion by pancreatic β-cells and/or insulin action. For the treatment of diabetes large numbers of herbal preparations are in vogue. Plant cells produced secondary metabolites which are biologically active constituents with therapeutic and prophylactic applications in humans.

Mangroves are the most productive ecosystems and contain highly diverse plants and microbial communities. Mangrove endophytes are proved to be a rich source of bioactive secondary metabolites. The biological molecules produced by endophytes play an important role in protection of mangrove plants against herbivores, insects as well as pathogens. The present study aimed to isolate the endophytic bacteria from the mangrove plant Rhizophora stylosa and screen antimicrobial and antioxidant activity of ethyl acetate extracts from the isolated endophytic bacteria.

Endophytic actinomycetes colonize in living plant tissues without causing harm to the host plant. In fact, they are regarded as effective bio-control agents and plant growth promoters due to their ability to activate plant self-immunity and produce biologically active secondary metabolites. Recent studies reported higher rates in finding new strains and antimicrobial substances among endophytes than actinomycetes from soil and plant surface.

Our previous studies revealed that the double variant of cytochrome P450 (CYP)105A1, R73V⁄R84A, has a high ability to convert vitamin D3 to its biologically active form, 1a,25-dihydroxyvitamin D3 [1a,25(OH)2D3 ], suggesting the possibility for R73V⁄R84A to produce 1a,25(OH)2D3 . BecauseActinomycetes, including Streptomyces, exhibit properties that have potential advantages in the synthesis of secondary metabolites of industrial and medical importance

The class of nonribosomally assembled siderophores encompasses a multi-tude of structurally diverse natural products. The genome of the erythro-mycin-producing strainSaccharopolyspora erythraeacontains 25 secondary metabolite gene clusters that are mostly considered to be orphan, including two that are responsible for siderophore assembly.
