Application endophytic microorganisms in agriculture and production of substances of economic interest Aplica o de microrganismos endofíticos na agricultura e na produ o de substancias de interesse econ mico

Endophytic microorganisms are mainly fungi and bacteria that live inside plants, generally inhabiting aerial parts such as leaves and stems, without causing any apparent damage to their hosts. In addition to many important functions for the host, the endophytic microorganisms are potentially useful in agriculture and industry, especially in pharmaceuticals and agrochemicals. By forming themselves into substitutes for chemicals by exercising stock biocontrol and/or promotion of plant growth, favoring theenvironmental preservation, has been appointed as a viable alternative agricultural production systems for environmentally and economically sustainable. Obtaining substances of economic interest, such as enzymes, antibiotics and other drugs from endophytic microorganisms has often been reported in the scientific literature. One example is taxol, a powerful anti-cancer substance that was previously obtained only from the exploitation of the plant Taxus brevifolia, and can now be obtained from different genera of endophytic fungi. Advances like this reinforce the great biotechnological potential of such microorganisms. This study presents an overview of potential applications of endophyticmicroorganisms in agriculture and production of substances of economic interest.
