“…This increased count in BPD has been attributed to the diverse bacterial populations present in poultry droppings in addition to nutrients contained in it (Williams et al 1999; Ijah and Antai 2003). This finding is in line with the report of El-Nawawy et al (1992) that combining oily sludge with the application of inorganic fertilizers gave higher numbers of aerobic bacteria months after application when compared with untreated sediments. Amendment of the crude oil-polluted sediments with the various nutrient regimen stimulated more microbial proliferation in the sediments.…”

Crude oil-polluted marine sediment from Bonny River loading jetty Port Harcourt, Nigeria was treated in seven 2.5 l stirred-tank bioreactors designated BNPK, BNK5, BPD, BNO3, BUNa, BAUT, and BUK over a 56-day period. Five bioreactors were biostimulated with either K2HPO4, NH4NO3, (NH4)2SO4, NPK, urea or poultry droppings while unamended (BUNa) and heat-killed (BAUT) treatments were controls. For each bioreactor, 1 kg (wet weight) sediment amended with 1 l seawater were spiked with 20 ml and 20 mg of crude oil and anthracene which gave a total petroleum hydrocarbons (TPH) range of 106.4–116 ppm on day 0. Polycyclic aromatic hydrocarbons (PAH) in all spiked sediment slurry ranged from 96.6 to 104.4 ppm. TPH in each treatment was ≤14.9 ppm while PAH was ≤6.8 ppm by day 56. Treatment BNO3 recorded highest heterotrophic bacterial count (9.8 × 108 cfu/g) and hydrocarbon utilizers (1.15 × 108 cfu/g). By day 56, the percentages of biodegradation of PAHs, as measured with GC–FID were BNK5 (97.93%), BNPK (98.38%), BUK (98.82%), BUNa (98.13%), BAUT (93.08%), BPD (98.92%), and BNO3 (98.02%). BPD gave the highest degradation rate for PAH. TPH degradation rates were as follows: BNK5 (94.50%), BNPK (94.77%), BUK (94.10%), BUNa (94.77%), BAUT (75.04%), BPD (95.35%), BNO3 (95.54%). Fifty-six hydrocarbon utilizing bacterial isolates obtained were Micrococcus spp. 5 (9.62%), Staphylococcus spp. 3 (5.78%), Pseudomonas spp. 7 (13.46%), Citrobacter sp. 1 (1.92%), Klebsiella sp. 1 (1.92%), Corynebacterium spp. 5 (9.62%), Bacillus spp. 5 (9.62%), Rhodococcus spp. 7 (13.46%), Alcanivorax spp. 7 (13.46%), Alcaligenes sp. 1 (1.92%), Serratia spp. 2 (3.85%), Arthrobacter spp. 7 (13.46%), Nocardia spp. 2 (3.85%), Flavobacterium sp. 1 (1.92%), Escherichia sp. 1 (1.92%), Acinetobacter sp. 1 (1.92%), Proteus sp. 1 (1.92%) and unidentified bacteria 10 (17%). These results indicate that the marine sediment investigated is amenable to bioreactor-based bioremediation and that abiotic factors also could contribute to hydrocarbon attenuation as recorded in the heat-killed (BAUT) control.

“…The decrease may be due to inhibitory effects of the components of chicken droppings or fertilizer on soil bacteria. This finding is however, contrary to the report of EL-Nawawy et al (1992) that, combining oily sludge with the application of inorganic fertilizer gave higher numbers of aerobic bacteria months after application compared with untreated soil. One reason for the higher bacterial counts in oil-polluted soil than the oil-free soil was probably because the oil served as a source of carbon and energy to the organisms and therefore, encouraged their proliferation.…”

“…Enhanced crude oil biodegradation in soil using organic manure or chemical fertilizer has been reported elsewhere (Sandvik et al 1986;El-Nawawy et al 1992;Ijah & Antai 2003a;Philp & Atlas 2005;Ubochi et al 2006;Abu & Onisuru 2006). The enhancement may be due to nutrients (nitrogen and phosphorus) present in the chicken droppings and fertilizer.…”

“…Some substances in this category include petroleum subsidiaries, aliphatic and sweet-smelling hydrocarbons, mechanical solvents, pesticides and metals (Korda et al, 1997;Ojewumi et al, 2018d ). Of all the technologies and methods that have been researched into in the recent past for cleaning up oil spills on soils, bioremediation has come out as the most desirable approach due to its low cost and ability to hinder the formation and accumulation of contaminants (El-Nawawy et al, 1992). Bioremediation is a term used to describe a process that takes advantage of the natural ability of microorganism to degrade toxic waste.…”

The study was done to investigate the kinetics of first order bioremediation. The effectiveness of remediating soils polluted with raw crude oil and treated crude oil using Aspergillus niger (fungi) and Pseudomonas aeruginosa (bacteria) were investigated. Eight systems of 500g soil sample were polluted with both raw and treated crude oil. Four systems were polluted with 40g treated crude oil while the other remaining four systems were polluted with 40g raw crude oil. Two systems with raw crude and treated crude were left as control (RCC and TCC). Raw crude samples were treated with Aspergillus niger only (RCA) and Pseudomonas aeruginosa (RCP) while treated crude samples were also treated with same (TCA) and (TCP) only. The last two systems were treated with both Pseudomonas aeruginosa and Aspergillus niger (RCAP and TCAP). The first order bioremediation kinetics and biostimulant efficiency for these systems were studied by monitoring Total Petroleum Hydrocarbon (TPH). At the end of the bioremediation period, the results obtained showed that treated crude oil polluted soil generally remediated faster and better than raw crude oil polluted soil. The highest level of bioremediation occurred in systems amended with both Pseudomonas aeruginosa and Aspergillus niger which had about 98% TPH decrease.
