“…The changes in physiochemical parameters during the bioremediation period showed substantial percentage decreases from day 0 to day 28 in both diesel polluted soil stimulated with cow dung and sawdust Table 4.These reductions indicated that the hydrocarbon degraders were actively utilizing the organic nutrient of nitrogen, phosphorus and potassium respectively. Similar observations have been made by Odokuma and Akpokodje (2004) and Odokuma and Okara (2005). The slight changes in the un-amended soil, control set up indicate that the indigenous micro-organisms in the diesel polluted soil were capable of utilizing the nutrients, but in low capacity, since there was no nutrient suplements to stimulate microbial growth as to enhance pollutant degradation.…”

The study was aimed at exploring the use of cow dung (CD) and sawdust (SD) as bio stimulants for enhanced ex-situ bioremediation of diesel fuel contaminated soil. Results of the microbial populations in a gram of soil showed that diesel polluted soil amended with CD had the highest total culturable heterotrophic bacterial (TCHB) population range (1.42 x 10 6-1.56 x 10 7 Cfu/g), total fungal (TF) (1.0 x 10 6-1.60x10 7 Cfu/g), hydrocarbon utilizing bacteria (HUB) (4.5 x 10 6-2.05 x 10 7 Cfu/g) and hydrocarbon utilizing fungi (HUF) (3.5 x 10 6-1.3 x 10 7 Cfu/g) respectively during the study. Diesel polluted soil amended with SD had lower TCHB populations (1.32 x 10 6-2.0 x 10 7 Cfu/g), TF (6.0 x 10 6-3.6 x 10 7 Cfu/g), HUB (5.4 x 10 6-1.28 x 10 7 Cfu/g) and HUF (1.2 x 10 6-2.0 x 10 6 Cfu/g) respectively, while the microbial populations in option C (control) were TCHB (1.

“…The decline in pH with time could be due to the production of acidic metabolites (Delyan et al, 1990). Odokuma and Okara (2004) attributed the pH of various treatments to be a function of the chemical composition of the treatment, which was related to the nature of the carbon source and other nutrients present, thus signifying that tobacco leaf dust had potential of fertilizing the pond as reported by Aleem (1987). The acidic condition of the water had resulted in the decrease in level of dissolved oxygen, free carbon (iv) oxide and temperature with a corresponding increase in the values of total alkalinity and conductivity.…”

“…BOD represents the amount of oxygen required for microbial decomposition of organic matter in waste water sample, it is roughly proportional to the amount of degradable organic matter present in the water sample (Nester et al, 2001). (Odokuma and Akpokodje, 2004;Odokuma and Okara, 2005).…”

Petroleum oil sludge resulting from crude oil storage, illegal crude oil refining and bunkering activities constitutes environmental hazards and pollution in the crude oil producing communities in the Niger Delta region of Nigeria. Biostimulation with N.P.K. fertilizer option C, bioargumentation with indigenous hydrocarbon utilizing bacteria (HUB) option B, combination of biostimulation and bioaugmentation as option A and option D was without any bioremediation treatment were employed in the bioremediation of brackish water artificially polluted with petroleum oil sludge. Brackish water sample was obtained from Elechi Creek, Port Harcourt Rivers State. Petroleum oil sludge sample was obtained from Crude Oil Processing Plant in Obegi community, Rivers State. Bioremediation was monitored for 56 days using the percentage ratio of total petroleum hydrocarbon (TPH) losses for each period to TPH loss at day 0. The result of physicochemical analysis of the petroleum sludge showed that aliphatic hydrocarbon (n-alkanes) ranged from C 13 -C 35, with concentrations ranging from 26.12-7,713.62ppmwith TPH of 89,509.9ppm. The polycyclic aromatic hydrocarbon (PAH) range was 0.03-5.36ppm with total concentration of 24.21ppm. Heavy metal analysis showed; iron (49.42mg/kg), Zinc (3.79mg/kg), Nickel (4.53 mg/kg) and manganese (6.90 mg/kg). The average total heterotrophic bacterial (THB) and (HUB) counts for petroleum sludge were; 2.5 x 10 5 cfu/g and 2.0 x10 5 cfu/g and for the brackish water sample were 1.39 x 106cfu/ml and 1.1 x 10 4 cfu/ml respectively. Statistical analysis (ANOVA) showed that the THB and HUB counts were significantly different at 5 percent levels (P<0.05) in the different treatment options during the bioremediation period. Changes in physico-chemical parameters showed that pH, alkalinity, conductivity, chemical oxygen demand, nitrate and phosphate were significantly different (P<0.05) while there were no significant differences (P>0.05) in the following parameter; salinity biochemical oxygen demand and total hydrocarbon continent.Using least significant difference (LSD), treatment option D and the control option E were different from treatments A, B and C. The phylogenetic analysis identification of the HUB isolates implicated in the degradation process revealed a closely related ness to the following organisms, Lysinibacillus sphaericus, Klebsiella pneumonia and Alcaligenes faecalis of different strains. The bacterial sequences submitted to Genbank were assigned Accession Number KX817218-KXV7225. The percentage losses in TPH from Gas Chromatography (GC) results showed the following; option A (91.8%), option B (92.5%), C (95%) D (57.8%) and option E control (39.5%) respectively. The results suggest that the application of biostimulation with N.P.K fertilizer, bioaugmentation with indigenous HUB or a combination of both will enhance the bioremediation of petroleum sludge polluted brackish water system in the Niger Delta of Nigeria.
