Evaluation of Kinetic Parameters of Total PetroleumHydrocarbon Degradation Using Grape Leaf as Nutrientto Catalyze the ReactionBy Ukpaka Chukwuemeka Peter, Chie Amadi Grace Orluma, Victor Chukwuemeka Ukpaka, Joy Chukwuemeka Peter Ukpaka, Abraham Peter Ukpaka
Abstract: The outcomes of the research are to determine and evaluate the kinetic parameters of total petroleum hydrocarbon degradation using grape leaf as nutrient to catalyze the reaction. The application of the Michaelis–Menten model equation in combination with the Lineweaver–Burk Plot theoretical conceptual techniques was adopted in handling the computation of the functional parameters and coefficients of the system. The impact of bio-remediant dosage was monitored, and the kinetic parameters were …

Investigation on the Comparison of the Physical Properties of Stimulants for Petroleum Hydrocarbon Remediation in SoilBy Ukpaka Chukwuemeka Peter, Samuel Nkanata Philip, Victor Chukwuemeka Ukpaka, Joy Chukwuemeka Peter Ukpaka, Abraham Peter Ukpaka
Abstract: Crude oil pollution is a major environmental concern that can cause significant damage to soil ecosystems. Bioremediation, a natural process in which microorganisms degrade pollutants, has emerged as a promising approach for the remediation of crude oil-contaminated soil. Grape leaf powder (Vitis Vinifera), a readily available and inexpensive organic material, has been shown to stimulate microbial activity and enhance bioremediation. This study investigated the effectiveness of grape leaf powder as …

Heat Generated Simulation with Bacteria and Fungi inCrude Oil Remediation in an Aerated LagoonBy Ukpaka Chukwuemeka Peter, Victor Chukwuemeka Ukpaka, Joy Chukwuemeka Peter Ukpaka, Abraham Peter Ukpaka, Obinuchi Wali
Abstract: Studies on the heat generated by bacteria and fungi in an aerated lagoon were monitored by theapplication of MATLAB computed software simulation. Mathematical models were developed in termsof substrate utilization by microbes and correlated with the Monod’s equation model which revealedthe trend of heat generated at different operating temperature of 15°C, 30°C, 45°C, 60°C, 75°C, 90°C,105°C and 120°C. The heat generated varies with increase in the microbial concentration as favoredby …

Total Petroleum Hydrocarbon Degradation with the Action of Bio-stimulant using NPK FertilizerBy Victor Chukwuemeka Ukpaka, Joy Chukwuemeka Peter Ukpaka, Abraham Peter Ukpaka, Ukpaka Chukwuemeka Peter
Abstract: The total petroleum hydrocarbon degradation with the action of bio-stimulant using NPK fertilizer was monitored with respect to different concentration of dosages. The nature of the curve in relationship to the establishment of the equation of the line as well as the square root of the best of each line or curve was considered. The application of this concept enhanced the determination of the kinetic values of each bioreactor process, …

Evaluation of Kinetic Parameters of Crude Oil Remediation Using Bio-Stimuant of Mint Leaf (Mentha piperita)By Abraham Peter Ukpaka, Victor Chukwuemeka Ukpaka, Joy Chukwuemeka Peter Ukpaka, Ukpaka Chukwuemeka Peter
Abstract: Kinetic parameters of crude oil degradation as related to total petroleum hydrocarbon (TPH) were evaluated. The experiment was set-up using crude oil, loamy soil polluted and addition of bio-stimulant (nutrient based substance). The depletion of the pollutant was monitored within the contact time of 7 to 35 days. At intervals of 7 days samples were collected and analyzed to determine the TPH concentration at each bioreactor set-up, through subjecting the …

Bio-stimulation with Fresh Avocado Seed for Crude Oil Remediation: Experimental and Bio-kinetic ModellingBy Joy Chukwuemeka Peter Ukpaka, Victor Chukwuemeka Ukpaka, Abraham Peter Ukpaka, Ukpaka Chukwuemeka Peter
Abstract: The remediation of crude oil-contaminated soils requires sustainable and cost-effective solutions. This study investigates the performance of fresh avocado seed (Persea americana) as a biostimulant for the remediation of Bonny Light crude oil-contaminated soil from the Kalarugbana community, Niger Delta. A 56-day laboratory-scale experiment was conducted using bioreactors containing 1 kg of soil contaminated with 100 ml of crude oil and treated with different volumes of fresh avocado seed slurry …
