Revisión de bacterias asociadas al cultivo de variedades de banano Musa spp. con potencial biotecnológico para el desarrollo de inoculantes

Abstract

Abstract:Banana (Musa spp.) is an important fruit crop with high nutritional value because it is a rich source of potassium and vitamins, making it an essential element in many diets. It is grown in more than 120 countries with an annual production of approximately 104 million tons, being a key product for the economy of many countries, especially developing countries. Currently, there is great interest in improving banana crop production, since there are several production problems due to the use of agrochemicals, inorganic fertilizers, and high volumes of irrigation water. In view of this, advances have been made in agricultural technologies that have brought real benefits to sustainable agriculture, seeking to increase crop yields and at the same time reduce the use of inputs by using certain groups of soil microorganisms, such as bacteria, in crops. In the specific case of banana, there are several studies focused mainly on the identification of microorganisms, however, there is not a complete vision of the potential that bacteria can have. In this review, we gathered and analyzed the scattered information and provided a broad view of the biotechnological potential for agriculture of bacteria associated with Musa spp. varieties. This review contains information on rhizobacteria, and endophytic bacteria associated with banana cultivation, with regard to plantations in different countries, information on the species, ecology, modes of action and functions. This review was limited to relevant studies conducted during the last two decades that can help to improve the understanding of the use of beneficial microorganisms to optimize banana production.
