ABSTRACT
Abundant endophytes are discovered, isolated from various tissues of plants. With the advancement of biotechnology, research indicating the value-added scope of endophytes has increased globally. The intense diversity and unique host interaction capability of endophytes is an untapped source of generating novel compounds. Endophytes seem beneficial to the host plants in providing additional resources at the time of any biotic and abiotic stresses. They help in relieving stress through the production of valuable secondary metabolites, extracellular enzymes, and nutrients. Endophytes are proficient enough to resist the toxic substances released by host plants to limit their growth by producing extracellular enzymes. Extracellular hydrolases consist of cellulase, proteases, amylases, lipases, pectinases, xylanases, chitinases, which function outside the endophyte microbial cell in many biological and environmental stresses. The prospecting of endophytes for the production of extracellular hydrolases is encouraging. The likelihood of isolation and quantification of novel extracellular hydrolases will be satisfactory as substitutes for specialized industries. The current chapter emphasizes disclosure of the sources, types of hydrolase enzymes, and the outlook for promoting adequate research for enhancing the applications of endophyte-derived extracellular hydrolases.
