Microbial Populations Occurrence in the Domestic Wastewater and Food Industry Effluents

Background and Objective: The development of sustainable pollution control necessarily involves the microbial community of the polluted environment. The current investigation attempts to isolate a population of bacterial colonies, identification of microbes from domestic greywater and wet grinding and pickle industries’ effluents. Materials and Methods: Samples of domestic greywater (GW) and effluents from the wet grinding industry (WGI) and pickle industry (PI) for the isolation and identification of bacterial and fungal colonies. Standard procedures were performed, including Gram staining and biochemical tests. Analysis of the ANOVA revealed significant variation (p≤0.05) in the Colony Forming Unit (CFU) of wastewater samples. Results: Abundant microbial load of microbial community was found in the raw pickle industry effluent samples, followed by wet grinding industry effluent samples. Whereas, grey water was determined with a relatively low microbial population. However, fecal contamination indicator of Coliform bacteria was noticed in greywater alone. Yeast colonies were noticed in untreated wet grinding industry effluent. An organic acid-rich pickle effluent was detected with Citrobacter species. Conclusion: Microbial communities inventory in wastewater and food industry effluents revealed the biological quality of wastewater and further would provide the method to develop proper management principles and guidelines, for the improved water quality.
