      INTRODUCTION
      Microbial growth is defined as increase in number of
       cells, not the size of the cells.
      Microbial cells obtain all required nutrients from food
       nearby.
      Food may be plant or animal origin.
      Each type of food has its own characteristic constituents
       which may affect the growth of microbial cells.
      The growth depends on the availability of nutrients and
       other factors present over there.
       FACTORS  AFFECTING MICROBIAL GROWTH 
     Factors  affecting microbial growth 
     In general, there are of two types of factors exist: 
      (i) Intrinsic Factors : pH, moisture etc. 
      (ii) Extrinsic Factors : Temperature, Oxygen etc.
