Bacteria in a closed bioreactor grow and decay in four stages because they sterile culture of cells. It a bioreactor incorporates environmental conditions such as temperature, dissolved gases and nutrient concentration that integrate to help bacteria and eventually decaying. The underlying conditions make the bacteria to grow to maximum level. Since the bacteria is in a closed bioreactor, the underlying conditions become more as the maximum growth is attained thus leading to their decay.
In the lag phase, growth and reproduction has just begun. Inoculum is the bacteria undergoing metabolism and the environmental conditions required include nutrient limitation, inhibitors, moderate temperature and spore germination.
In the log phase, bacteria is becoming more active with reproduction taking place very fast. cyano is the bacteria undergoing metabolism and the environmental conditions required include nutrient high temperature, high pressure and amino acid supplements.
In the stationary phase, the environmental conditions and food supply are not able to support growth. Antibiotics are the bacteria-undergoing metabolism and the environmental conditions required include oxygen concentration, PH and nitrogen requirements.
In the death phase, all the nutrients have been used up as a result, the population dies. The environmental conditions required include nutrient limitation, low or high temperature and living wrong conditions.
Carbon, Energy source and electron acceptor
If prototroph bacteria are used to treat latex in the presence of ammonium sulphate in a bioreactor, the carbon source would be carbon (IV) oxide. In addition, the energy source would be biogas and the electron acceptor would be the sulphate.
