Contamination of soil by textile effluent is a major threat found worldwide. These pollutants have diverse range of negative effects on the ecosystem, therefore restoration through cost effective biological strategy is the need of the hour. The aim of the current study was to enhance the decolourization of reactive green dye (RGD) using phytoremediation coupled with augmentation of effective bacteria to the rhizosphere. The isolate Klebsiella sp. VITAJ23 was isolated from textile effluent polluted soil and was assessed for its plant growth promoting traits (PGP) and the PGP functional genes were amplified. The soil was artificially polluted with RGD concentration ranging from 1000 to 3000 mg kg⁻¹ and Alternanthera philoxeroides plantlets were planted in phyto and rhizoremediation treatments, the setup was maintained upto 60 d. The isolate VITAJ23 was augmented in the rhizoremediation setup and the morphological parameters were assessed at regular interval. There was a significant increase in the chlorophyll content as well as root and shoot length of the plant when treated with the bacterial suspension. Decolourization study revealed 79% removal of reactive green dye with an enhanced oxido-reductase enzyme activity in the setup bioaugmented with bacteria. The biodegraded metabolites were identified as 2-allylnapthalene, l-alanine, n-acetyl-and propenoic acid by GC–MS analysis and a plant-bacteria degradation pathway was predicted using computational tools. Inoculation of PGP-Klebsiella sp. VITAJ23 enhanced the rate of plant growth and dye degradation.

纺织废水污染土壤是世界范围内的主要威胁。这些污染物对生态系统的负面影响范围各不相同，因此通过成本有效的生物策略进行恢复就成了当务之急。当前研究的目的是通过使用植物修复以及将有效细菌增加到根际来增强活性绿色染料（RGD）的脱色。分离株克雷伯菌。从纺织废水污染的土壤中分离出VITAJ23，并对其促进植物生长的性状（PGP）进行了评估，并扩增了PGP功能基因。土壤被人为与RGD浓度范围为1000〜3000毫克公斤污染^-1和水花生将小植株种植在植物和根际处理中，其设置维持至60 d。分离株VITAJ23在根治治疗中得到增强，并定期进行形态学参数评估。用细菌悬液处理后，植物的叶绿素含量以及根和芽的长度显着增加。脱色研究表明，在以细菌为生物增强剂的设备中，具有增强的氧化还原酶活性的活性绿色染料的去除率达79％。通过GC-MS分析鉴定出生物降解的代谢物为2-烯丙基萘，1-丙氨酸，正乙酰基和丙酸，并使用计算工具预测了植物-细菌的降解途径。接种PGP-克雷伯菌sp。VITAJ23提高了植物生长和染料降解的速度。
