Currently, there is an absolute concern for all nations in agricultural productivity to meet growing demands of human population. In recent time, biosurfactants produced by diverse group of microorganisms are used to achieve such demands as it is known for its ecofriendly use in elimination of plant pathogens and for increasing the bioavailability of nutrients for plants. Endophytic fungi are the important source of secondary metabolites and novel bioactive compounds for different biological applications. In the present study, endophytic fungi recovered from the cones of was evaluated for its biosurfactant producing ability and plant growth-promoting abilities through various screening methods and also via its antagonistic activity against phytopathogens like . In addition, was also tested for a various range of growth parameters in chilli under greenhouse conditions. Significant increase in shoot and root length, dry matter production of shoot and root, chlorophyll, nitrogen, and phosphorus contents of chilli seedlings was found, which reveals its ability to improve the growth of crop plants. Hence, this study suggests the possibility of biosurfactant producing endophytic fungi as a source of novel green biosurfactant for sustainable agriculture to achieve growing demands.
目前，所有国家都非常关注农业生产力，以满足不断增长的人口需求。最近，人们利用多种微生物产生的生物表面活性剂来满足这些需求，因为它在消除植物病原体和提高植物养分的生物利用度方面具有环保的特点。内生真菌是次生代谢物和新型生物活性化合物的重要来源，可用于各种生物应用。在本研究中，从 的球果中分离出内生真菌，并通过各种筛选方法以及对 等植物病原菌的拮抗活性来评估其生物表面活性剂产生能力和植物促生能力。此外，还在温室条件下对 进行了一系列辣椒生长参数的测试。结果发现，辣椒幼苗的茎和根长、茎和根干物质产量、叶绿素、氮和磷含量均显著增加，这表明它有能力促进作物生长。因此，本研究表明，产生生物表面活性剂的内生真菌 有可能成为可持续农业中新型绿色生物表面活性剂的来源，以满足不断增长的需求。
