A study of isolation and identification of bacteria from lake water in and around Udaipur, Rajasthan

INTRODUCTION: Water is an essential nutrient which plays an important role in digestion, absorption of food and elimination of waste products by urine. Udaipur also known as ‘City of Lakes’ or even the ‘Venice of East’ due to its unique and beautiful lake system has an exceptional importance at national and international levels. The aquatic systems are mostly dominated by bacteria and fungi and in the natural environments micro-organisms have very specific roles with regard to the recycling of materials and purification of water. Presence of coliform bacteria in the water indicates the fecal pollution of water. METHODS: Water from all the three lakes were included for the assessment of their water quality parameters. Biological parameters like MPN of coliforms and presence of bacterial and cyanobacterial contaminants were read. The MPN (Most Probable Number) of Coliform was determined by the Presumptive Coliform Count (Multiple Tube Method) in 100 ml of sample water. CONCLUSION: The coliform bacteria is the primary bacterial indicator for fecal pollution in water. The purpose of study was to make people aware about the bacterial load in water bodies. Based on this, categorical representation of water was unacceptable for the purpose of swimming and bathing.
