Endophytes: A Hidden Treasure of Novel Antimicrobial Metabolites

  • Chapter
  • First Online:
Antibacterial Drug Discovery to Combat MDR

Abstract

An endophyte is a microorganism which colonizes the healthy tissues of the host plant without causing any symptoms of disease. The relationship between the endophyte and the host ranges from latent phytopathogenesis to mutualistic symbiosis. Endophytes obtain nutrition and protection from plants and, in return, help their hosts to adapt to different ecological stress conditions by producing certain functional metabolites. Consequently, endophytes are usually metabolically more active than their non-endophytic counterparts. By virtue of their functions in nature, endophytes produce multitude of natural products, particularly those having potential antimicrobial activities. As all the plants analysed for endophytism have been found to possess such organisms, endophytes represent a comparatively unexplored as well as a huge reservoir of bioactive metabolites. In this chapter, an effort is made to present an overview of the potential of endophytic microorganisms as a source for antimicrobial agents.
