Growth Pattern of Microorganisms
• These growth stages are important for sewage
treatment processes
• Food becomes the limiting factor in further growth in
between log phase and stationary phase. This is called
declining growth phase and is generally used for
biological treatment systems
• To produce maximum amount of microbes and
microbial products, they must be consistently
provided with new nutrients to prevent them from
entering the stationary phase
