Figure 4: Total Culturable Hydrocarbon Utilizing Bacteria counts. Key: BUNa (Un-amended control); BHKD (Heat killed contol); BNPK (NPK); BAUG (Bioaugumentation); BURE (Urea); BPOUT (Poultry dropping); BCD (Cow dung). BHKD recorded no bacterial growth throughout the 64 day period of experimentation. BUNa showed statistically significant difference when compared to other amended treatments. There were significant differences in TCHUB counts when the bioaugumented slurry was compared with those amended with NPK, Urea and cow dung.
