Abstract

Wastewater samples from abattoirs in Bayelsa and Rivers State were evaluated for their microbiological and physicochemical properties. The microbiological parameters were analyzed using standard microbiological techniques while the Physicochemical parameters were analyzed based on the APHA standard method. The mean range of the total heterotrophic bacterial, bacterial, total coliform, total Vibrio, total hydrocarbon utilizing, total heterotrophic fungal and hydrocarbon utilizing fungal counts of the wastewater were: (1.9×107to 5.2×107, 2.1×105 to 4.0 × 105, 1.0×103 to 3.1 × 103, 1.0×105 to 2.2×105, 1.8×105 to c4.1×105 and 1.1×103 to 3.2 ×103)CFU/ml respectively. Kruskal-Wallis H test showed that there was no significant difference (P≥0.05) in the counts for the bacterial and fungal counts. Bacillus sp (17.32%), Escherichia coli (16.33%), Streptococcus sp (15.34%), Staphylococcus sp (14.35%), Pseudomonas sp (11.38%), Shigella sp (10.39%) Alcaligenes sp (9.9%), Vibrio sp (6.93%) and Salmonella sp (4.93%), were the bacteria isolated. The percentage of occurrence of hydrocarbon utilizing bacteria isolates were: Bacillus sp (34.28%), Pseudomonas sp (26.71%), Alcaligenes sp (20%). Escherichia coli (14.28%), Staphylococcus sp (5.71%). Among the fungi isolated Aspergillus niger, Fusarium sp, Geotrichum sp were found in 18.75% each while Penicillium sp recorded 23% occurrence, Aspergillus fumigatus and Candida sp were found in 6.25% occurrence each but Mucor sp exhibited 8.33% of occurrence. The percentages of occurrence of hydrocarbon utilizing fungi were Aspergillus sp (22.22%), Fusarium sp (16.66%), Penicillium sp (33.33%), Geotrichum sp (16.66%), Mucor sp (5.55%) and Candida (5.55%). The mean of physicochemical parameters was: pH: 6.7-9.1, EC: 156-4981, Turbidity: 11.1-149NTU, TSS: 62-239, TDS: 104-3320, NO3: 20.97-30.97, SO4: 14.5-54.6, PO4: 1.78-20.21, salinity: 41.25-2800, DO: 4.29-41.18, COD:3600-5476.0 and BOD-:1600.0-7761.4. The high microbial load and physicochemical parameters in these wastewaters is alarming and could pose serious human health and environmental challenges if the disposal of untreated wastewater continues unabated.
