In recent years, there has been an increasing demand for the isolation and identification of new microbial polysaccharides that can compete with traditional polymers because of their improved chemical and physical properties, higher flocculating and emulsifying activities, and Microbial polysaccharides have pesticidal activities. Over the past few decades, chemical pesticides were widely used in agricultural practices. However, the widespread and prolonged use of these chemical pesticides resulted in bio-magnifications of insecticides and insecticide resistance, which in turn resulted in the export of agricultural products. The main advantages of biopesticides are less harmful, designed to affect only one specific pest, very effective in very small quantities, degrade quickly and with very less pollution. Currently, emergence of drug resistant bacterial strains has put forward an immediate need for other alternatives of antibiotics which can be efficient in controlling the infectious conditions caused by these strains. EPSs from such bacteria can serve as better and may be the novel source to combat such infections. Therefore, the present study was aimed to isolate efficient EPS producing bacteria. Studied the extracellular polysaccharide producing bacteria Xanthomonas Isolate and identified by biochemical characterization to This work attempts to synthesize xanthan using infected part of lemon by batch fermentation method. And finally, the effect of larvicidal and antibacterial activity was checked.
