The biological treatment of wastewaters (municipal and industrial) is an important topic in the field of biochemistry and biotechnology, as well as in the field of environmental engineering. It has many advantages, such as the simple operation of the basic bioreactor, the potential for the production of valuable bioproducts and efficient wastewater treatment in a short time. However, the biological wastewater treatment also has certain downsides, such as air pollution in places which are near bio-lagoons, and endangering the health of personnel involved in this process. By studying and analyzing data from the reference literature, this paper provides a comprehensive overview of information on microorganisms involved in the wastewater treatment process, the factors with a negative effect on their development, as well as the negative effects of these microorganisms and the biological wastewater treatment process on the environment.
