—Wastewater is a combination of the liquid wastes conducted away from residences, hospitals and industrial establishments and treatment of wastewater is crucial for environmental and public health as treated wastewater is reused in many ways including drinking water. In a wastewater treatment plant, microorganisms and toxic chemical compounds are removed from wastewater by physical, chemical and biological methods to generate effluent wastewater.
Microorganisms play a critical role in activated sludge systems. A culture media is defined as a solid or liquid preparation used for the growth, transport, and storage of microorganisms which must contain all the nutrients required for the growth of the microorganism. The function of the media depends on its composition as well as the nutrients needed for the growth of all bacteria. It has been suggested that, no definitive standart exists for the assessment of culture media.
Herein, the aim of our study was to evaluate the effects of influent and effluent wastewater samples used in Mac Conkey agar on the growth of E. coli. Our preliminary results showed that influent wastewater was more effective on bacterial growth compared to effluent wastewater. The results of our preliminary findings need to be strengthtened with additional studies conducted using wastewater samples.
