Isolation and Screening of Phosphate Bacteria Showing Alkaline Phosphatase Activity

Abstract

India is basically an agricultural country. The economic stability of India is dependent on the agricultural yield. Modern agriculture is evolving with much greater emphasis on the efficiency of the production process than in the past & great deal of research has been carried in the last 50 years by agricultural scientists has its major thrust on increasing production and productivity. The process has gathered momentum with the development of high yielding varieties of crop plant in response to the challenge of feeding the rapidly increasing human populations in most developing countries. The new technology has already made an impact although the crop yields in most developing countries continue to be low relative to the genetic potential, which has been created. A major factor contributing to this gap is the heavy dependence on costly non-renewable resources of energy such as chemical fertilizers. Most developing countries do not have the industrial development, which helps to subsidize high input agriculture in developed countries. For this reason, and as a result of major scientific advances in the field of microbiology and molecular genetics in recent years, scientists are exploring new ways of meeting the nutrient needs of crop plant aiming at high productivity. Soil microorganisms like bacteria; cyanobacteria and fungi have a particularly important role in the exploration of these new approaches.
