Characterization of Bacterial and Fungal Populations Present in the Wastewater Released by the......

The goal of this study was to identify the bacterial and fungal concentrations found in the Ogbe slaughterhouse's wastewater. At two seasons, bacterial and fungal concentrations from Ogbe slaughterhouse wastewater were tested. Total heterotrophic bacterial count (2.0105-2.1105 cfu/mL) and total fungal count (1.5105-2.0105 cfu/mL) were obtained. Bacterial isolates of Acinetobacter sp. (0.50-3.65%), Citrobacter sp. (3.00-9.13%), Escherichia sp. (2.50-13.69%), Klebsiella sp. (2.50-14.16%), Proteus sp. (2.00-9.13%), and Staphylococcus sp. (11.00-13.69%) were greater in the dry season than in the Bacillus sp. (9.13-23%), Enterobacter sp. (0.00-3%), Micrococcus sp. (6.85-7.50%), Pseudomonas sp. (12.84-25.00%), Salmonella sp. (4.57-5.00%), Serratia sp. (0.00-1.50%), and Streptococcus sp. (4.57-13.00%) were all higher in the wet season than In the current investigation, mould isolates such as Absidia sp., Aspergillus sp., Fusarium sp., Cladosporium sp., Penicillium sp., and Rhizopus sp. were found. Apart from Penicillium sp., the percentage of detected mould isolates in wastewater for each season was higher than the control. Candida sp., Saccharomyces sp., and Torulopsis sp. were among the yeasts recovered from Ogbe abattoir wastewater in this investigation. When their potential risk as pathogens is evaluated, as well as the increased environmental health hazards they provide to humans living in the slaughterhouse environment, the observed isolates become significant.
