Abstract :

The present research is centered on the microorganism associated with aquatic nearby resources of Bay of Bengal. Different level of stress tolerance was studied for the isolated bacterial samples from Gostani River, Visakhapatnam, Andhra Pradesh, India. Multiple stress tolerant studies were studied on G3A strain.The isolate were found to be gram positive rod shaped spore forming motile Bacteria.The Biochemical analysis was prepared to recongnize the qualitative potential by the following conventional tests like Indole test,methyl red.voges proskauer,citrate utilization,Nitrate reduction,catalase,oxidase,and carbohydrate fermentation test.The G3A bacterial isolates were tested for their tolerance to different concentrations of salt in solid media(1–12%).In their natural environment ,bacteria most often,live in nutrient limiting conditions and are exposed to various stress such as Ultra Violet radiation was identified, Alkaline tolerant studies and heat shock treatment studies were conducted and the organisam was capable to sustain in the multiple stress tolerent levels.
