Abstract
Microbial endophytes have a long-standing association with numerous plant species. A closer look into their diversity indicates the existence of novel species from biologically diverse regions on the earth, especially the tropics. The novelty is related to their ability to produce diverse chemical structures with reliable bioactive potentials, which has resulted in the addition of new compounds to the unending list of natural products. Hyphenated techniques have fastened the cumbersome screening of crude extracts with reliable bioassays resulting in the elucidation of novel compounds or molecules of interest. Biotechnological approaches are of added advantage in the production of such compounds with remarkable bioactivities. This chapter highlights the fungi and actinomycetes as endophytes from the medicinal and pharmaceutical plants of relevance, host-related metabolites, novel bioactive metabolites of endophytes, and approaches for the augmentation of metabolites and a special mention of the metabolites by Pestalotiopsis species. Therefore, endophytes are microbial chemical factories more suited for the production of novel metabolites with therapeutic potentials.
