   Even if you "forget" to take care of me,

 I can adapt!

      Streptomyces Platensis have the ability to adapt to different conditions in soil thanks to the formation of numerous spores. Most of the spores produced are in a  semi dormant stage in the life cycle which helps for survival. Also, this bacterium has a wide range of pH tolerance: can live in a soil with a pH between 5 and 11.5 (on a scale of 0, acid, to 14, basic.). That implies that the bacteria can live in a polluted area where the pH gets lower (cf habitat). These bacteria have the ability to gain new valuable characteristics by lateral gene transfer if the pH changes for instance.

        The involvement of linear chromosomes is also really important for adaptation; but its mechanism is not as clear as the other adaptation behaviors. In fact, this bacterium is characterized by extrachromosomal elements used for transfers. The evolvement of linear chromosomes helps to exchange DNA during the conjugaison. As a remaining from the classification page, this bacterium is a gram positive bacterium which means there is not formation of pili between two Streptomyces platensis for the exchange. The scientist are still working on the question of chromosal exchange. It is still unclear on how the bacteria use the linear chromosomes to exchange information. However, it is a fact that there is an exchange and that it is helpful to adapt to a new habitat.
