Isolation, Biochemical Characterization and Production of Biopolymers by Phytopathogenic Species of Xanthomonas from the Plants of Rutaceae Family

Abstract

Plants of rutaceae family, such as Citrus medica (citron, bijaura), Limonia acidissima (stone fruit, elephant apple) and Citrus limon (lemon) are well known for their nutritive and medicinal values. They were analyzed for the presence of citrus cankers on their various body parts such as leaves, stems and fruits. Isolated species of Xanthomonas were subjected to biochemical characterization for their identification. Different media were used for the cultivation of these organisms as well as production of biolpolymer from them under laboratory conditions. Isolated species were subjected to cross infect these three members of rutaceae family to investigate their host range. Different sugars, such as glucose and sucrose were tested for optimization of xanthan production. Biopolymers from Xanthomonas spp. have got wide spread biotechnological applications.
