Title : Effect of Lysinibacillus macroids on the growth and surival of their associated cyanobacteria lyngbya sp
Cyanobacteria and bacteria are prokaryotic in nature but they vary greatly by their food habits. In the natural system they tend to associate with one another to compensate their needs. This study shows the isolation of cyanobacteria and their associated bacteria from the water samples of Bhitarkanika mangrove region and their interaction with each other. The cyanobacteria and its associated bacteria were isolated on BG-11 and nutrient agar media respectively. The cyanobacterium and bacterium were identified as Lyngbya sp. and Lysinibacillus macroids respectively. In this study the bacteria was found to have synergistic effect on the growth and biochemical properties of Lyngbya sp. the growth and other biochemical properties were found in co-cultured Lyngbya sp. than that of axenic cyanobacteria on the 9th day of incubation. The enhanced growth of cyanobacteria was found to be due to the secretion of growth enhancing factors such as IAA, Siderophore and Vitamin B12 by the associated bacteria in the culture medium. This study of cyanobacteria- bacteria association has an emerging application in the recent trends in biotechnology field, microalgae harvesting, waste water treatment, aquatic animal’s food etc.

This research can be used in waste water treatment and in various biotechnological fields for algal bloom control and algal harvesting. As microbes are known as contaminants, but they are useful in various industrial and biological fields.
