Isolation and Identification of the (Myxococcus xanthus) Myxobacterium from the Grave Soil

Abstract

  The study was performed to isolate and identify the Myxococcus
 
xanthus from (50) samples of  grave  soils .Special growth conditions had been used to support the growth of  M.
   xanthus and to suppressed the growth of other microorganisms like (Drying , High concentration of antibiotics and specific growth media)
 M. . xanthus  isolates had been subjected to the morphological, cultural and biochemical examinations for identification .  Results obtaind could be summarized as follows : 1. Myxobacteria were found as normal flora  inhabitants of the arid soils. 2. Ten local  isplates  of   M.  xanthus out of (50) soil samples were  isolated as fruiting bodies depending on baiting technique by baker ' s yeast. 3. Soil extract agar with baker 's yeast was suitable  for  obtaining the best growth of vegetative swarms as pure culture
