Mangroves are salt-tolerant forest ecosystem that extends between tropical and subtropical intertidal regions of the world. Mangroves are biochemically unique vegetation that produce wide array of natural products with immense medicinal potential. These plants are the most valuable resources and provide economic and ecological benefits to the coastal people. Natural products from these plants are of great interest as they provide innumerable direct and indirect benefits to human beings for the discovery of novel antimicrobial and other bioactive compounds. They possess active metabolites with some novel chemical structures that belong to diverse chemical classes such as alkaloids, phenol, steroids, terpenoids and tannins. Several mangrove species have been used in traditional medicine or have few applications as insecticide and pesticide. To date, several mangroves, and their associated species and solvent extracts are screened for antimicrobial activity along with the presence of potent bioactive compounds. The present article emphasizes and creates awareness about the potential mangrove plants and their associates as a source of biologically active compounds with potent antimicrobial properties. This paper also elaborates the mechanisms of action and various methods for screening of antimicrobial compounds.

AIM:
Mangrove is one of the oldest living tree species and its leaves are among the most extensively studied botanicals in use today. Scientific research throughout the world has found evidence to support the fact that its foliar extracts have great potential against human microbial pathogens. This study highlights the isolation of foliar fungi from Rhizophora mucronata, Avicenna officialis and Avicenna marina.
METHOD:
It was isolated in Sabouroud's Dextrose Agar and mass cultivation was done in Sabouroud's Dextrose broth.
RESULTS:
The ethyl acetate extract showed maximum antibacterial activity which inturn checked for different concentration against bacterial pathogens and anticancer activity for Hep2 and MCF7 cell line in vitro. The DNA was isolated from the fungi and the ITS region of 5.8 s RNA was sequenced and assigned to new species as they are separated from the type strains phylogenetic neighbors by sequence similarities.
CONCLUSION
This preliminary screening of fungal endophytes revealed their potential to yield potent bioactive compounds for drug discovery programmes.
