3. Stationary phase. As the bacterial population continues to grow, all the nutrients in the growth medium are used up by the microorganism for their rapid multiplication. This result in the accumulation of waste materials, toxic metabolites and inhibitory compounds such as antibiotics in the medium.he time taken by the bacteria to double in number during a specified time period is known as the generation time.
