摘      要：Addressing micronutrient deficiencies in agricultural soils to meet the growing demands of crops is a matter of great concern *** use of biosurfactant,a multifunctional microbial metabolite,to enhance nutrient availability may be a sustainable way of enhancing agricultural *** are generally less toxic than synthetic *** application of biosurfactants in agricultural soils is anticipated to improve nutrient status,increase wettability,and achieve a more even dissemination of complex *** studies have evaluated the influence of biosurfactants on bioremediation,antimicrobial activity,and soil flushing *** manuscript reviews the possibility of employing biosurfactants to mobilize and solubilize soil nutrients and make them available to plants through the formation of metal-biosurfactant *** significant progress regarding an explanation of the mechanisms behind many biosurfactant-induced effects has been made,there are still many aspects of this area that are not sufficiently elucidated,such as differences in specificity for nutrients(e.g.,Cu,Fe,Mn,and Zn)and toxins(e.g.,Cd and Pb).Biosurfactants from various isolates have been considered for their potential role in plant growth promotion and other applications related to improving the effectiveness of agricultural soils.
