摘要

背景:植物益生菌是一种活的微生物,能促进土壤健康和植物生长,并增强植物的抗逆能力。它们通过增加养分吸收和释放与压力有关的植物激素来使植物受益。与化肥相比,这些植物益生菌对植物的作用更大。使用砷和镉等化肥会导致土壤酸化,甚至释放甲烷等有害气体,进一步污染环境:结果:通过在选择性培养基上评估固氮能力和其他各种方法,从泰兰加纳州 Tattiannaram 的农田中分离出了不同的细菌物种,并确定其为具有促进植物生长重要品质的高效根瘤菌。在对分离菌进行分子鉴定后,确定其为棒状杆菌属、芽孢杆菌属、乳酸杆菌属和细胞杆菌属,并使用各种生物信息学工具对其系统发育模式的准确性进行了检验:结论:公认的植物益生菌物种在促进植物生长和增强植物免疫力方面具有公认的作用。本研究介绍了一种创新方法,用于评估和研究新近发现的细菌分离物,重点关注其独特的植物益生菌属性。通过利用优势微生物的潜力并理解它们与植物和土壤的相互作用,我们的目标是制定创新方法,以提高作物产量、增加土壤肥力并促进环境可持续发展和稳健的农业方法。这些特性显示了未来融入植物系统、强化生长和发育的巨大潜力,并凸显了它们在农业领域的独特意义。

Isolation of plant growth-promoting rhizobacteria from the agricultural fields of Tattiannaram, Telangana.

Background: Plant probiotics bacteria are live microbes that promote soil health and plant growth and build the stress-tolerant capacity to the plants. They benefit the plants by increasing nutrient absorption and release of stress-related phytohormones. These plant probiotic bacteria serve a better purpose to the plant when compared to chemical fertilizers. Use of chemical fertilizers such as arsenic and cadmium can lead to soil acidification and even release of harmful gases such as methane which further pollutes the environment.

Results: Different bacterial species were isolated from the agricultural fields of Tattiannaram, Telangana, and identified as the efficient rhizosphere bacteria with the essential qualities of plant growth promotion by evaluating the nitrogen-fixing ability on a selective media and various other methods. Upon the molecular characterization of the isolates, they were identified as Corynebacterium spp., Bacillus spp., Lactobacillus spp., and Cytobacillus spp. The results were also examined using various bioinformatics tools for accuracy in their phylogenetic pattern.

Conclusion: The recognized species of plant probiotics have established roles in promoting plant growth and strengthening plant immunity. This research introduces an innovative methodology for evaluating and investigating recently identified bacterial isolates, focusing on their distinctive plant probiotic attributes. Through harnessing the potential of advantageous microorganisms and comprehending their interaction with plants and soil, our objective is to formulate inventive approaches to elevate crop productivity, enhance soil richness, and foster environmentally sustainable and robust agricultural methodologies. These characteristics exhibit promising potential for future incorporation into plant systems, fortifying growth and development, and underscoring their distinctive significance within the realm of agriculture.
