Mangroves are woody specialized trees of tropics and are valuable flora contributing to economical, ecological, scientific and cultural resources. They thrive in salty environments like coastal regions and are aid towards disaster management facing the onslaught of giant waves such as Tsunami. Analysis of mangrove soil on the banks of the Adyar river behind the Theosophical society campus, Adyar, Chennai, India, gave a startling revelation of microorganisms that can tolerate different salinity ranges. Previous studies in Pichavaram delta, have reported bacterial isolates such as nitrogen fixing bacteria, halophiles and several others. However their efficiency in the growth of mangrove forest has been studied to a lesser extent. The present study has been designed and formulated to estimate halophilic (aerobic) bacterial load from mangroves soil sample based on depth and salinity of the soil and further the efficiency if any of these isolates in the growth of mangroves. Results have been correlated and a cohesive conclusion reached for further intensive research. This study throws light on the ecology of the bacterial population in the coastal marine environment inhabited bymangroves and its possible role in disaster mitigation.
红树林是热带地区的木本特色树种，是对经济、生态、科学和文化资源有贡献的珍贵植物群。它们在沿海地区等盐碱环境中茁壮成长，有助于应对海啸等巨浪冲击的灾害管理。对印度钦奈阿迪亚尔神智学社会校园后面阿迪亚尔河岸的红树林土壤进行分析，惊人地发现了能耐受不同盐度范围的微生物。此前在皮查瓦拉姆三角洲的研究报告了诸如固氮细菌、嗜盐菌等多种细菌分离株。然而，它们在红树林生长中的作用效率研究较少。本研究旨在根据土壤深度和盐度估算红树林土壤样本中的嗜盐（需氧）细菌数量，并进一步研究这些分离株在红树林生长中的作用效率（若有）。已将结果进行关联并得出了一个连贯的结论，以便进行进一步深入研究。这项研究揭示了红树林栖息的沿海海洋环境中细菌种群的生态及其在减灾中的可能作用。
