Plant-associated bacteria have already been considered as the store house of bioactive compounds that confer the plant growth promotion and disease protection. Hence, the unique plant parts have already been expected to harbor diverse microbial communities with multi-beneficial properties. Based on this, the current study has been designed to identify the potential of Serratia sp. NhPB1 isolated from the pitcher of Nepenthes plant for its activity against the infamous pathogen Pythium aphanidermatum. The in vitro antifungal, plant growth promoting and enzymatic activities of the isolate indicated its promises for agricultural application. The isolate NhPB1 was also demonstrated to have positive effect on Solanum lycopersicum and Capsicum annuum, due to its plant beneficial metabolites. From the results of LC–MS/MS analysis, the isolate has also been revealed to have the ability to synthesize bioactive compounds including salicylic acid, cyclodipeptides, acyl homoserine lactone, indole-3-acetic acid, and serrawettin W1. These identified compounds and their known biological properties make the isolate characterized in the study to have significant promises as an eco-friendly solution for the improvement of agricultural productivity.

植物相关细菌已经被认为是赋予植物生长促进和疾病保护的生物活性化合物的仓库。因此，人们已经预期独特的植物部分将隐藏具有多种有益特性的多种微生物群落。基于此，目前的研究旨在确定沙雷氏菌属的潜力。从猪笼草植物的猪笼草中分离出 NhPB1，因为它对臭名昭著的病原体 Pythium aphanidermatum 具有活性。该分离物的体外抗真菌、植物生长促进和酶活性表明其在农业应用中的前景。分离株 NhPB1 还被证明对 Solanum lycopersicum 和 Capsicum annuum 具有积极影响，因为它具有植物有益代谢物。从 LC-MS/MS 分析结果来看，该分离物还能够合成生物活性化合物，包括水杨酸、环二肽、酰基高丝氨酸内酯、吲哚-3-乙酸和 serrawettin W1。这些鉴定的化合物及其已知的生物学特性使研究中表征的分离物作为提高农业生产力的环保解决方案具有重要的前景。
