factors affecting soil microbial communities in niger delta

dilution plate method and direct plating of serially washed root segments on PDA and The two main drivers of soil microbial community structure, i.e., plant type and soil type, are thought to exert their function in a complex manner. 0000007964 00000 n Results of analysis indicate that about $669 billion was generated from the sales of crude oil between 1970 and 2010. Overall, growth enhancement efficiencies of the applied treatments were in the order: PSOFM ˃ PSOF ˃ PSOFMS. The intrinsic and enhanced hydrocarbons biodegradation rates were estimated from the slopes of linear regressions of cumulative curves of O-2 uptake. 2 † Bacillus sp. Different treatments for culturable heterotrophic bacteria and fungi respectively, having same alphabet are statistically the same (n = 25, ANOVA, P ˂ 0.05). 0000004777 00000 n 2 Aspergillus sp. Conclusion Culturable heterotrophic bacteria and fungi isolated from uncontaminated soil Bacteria Fungi Bacillus sp. and Azospirillum sp., among rhizosphere isolates. 67%. Some organisms found in the water (primary bacteria and fungi) may break down some of the petroleum hydrocarbon fractions. Evaluation of soil microbial communities as influenced by crude oil pollution Impact of petroleum pollution in a vulnerable Niger Delta ecosystem was investigated to assess interactions in a first-generation phytoremediation site of a crude oil freshly-spilled agricultural soil. 3 † Corynebacterium sp. This community is a host to a major oil company in Nigeria. The effect of oil concentration on height, root length and leaf area growth varied with plant species (P ˂ 0.05). As an alternative, the addition of plants can greatly improve bioremediation rates and outcomes as plants provide microbial habitats, improve soil porosity (thereby increasing mass transfer of substrates and electron acceptors), and exchange limiting nutrients with their microbial counterparts. 0000001590 00000 n Modifications in the count and activity of microorganisms may lead to upsetting the biological equilibrium of soil, which in turn depresses its fertility. in the root zones (rhizosphere and rhizoplane) and non-rhizosphere soil of S. officinarum were assessed quantitatively There were 44.4, 71.8, 74.7, and 67.5, and 50.5, 71.8, 82.3, and 71.8% reduction in residual TPH in soil planted with P. australis and E. crassipes respectively for treatments PSO, PSOF, PSOFM, and PSOFMS as against 20.0, 62.6, 67.5, and 67.5% losses in SO, SOF, SOFM, and SOFMS. Results indicated that while culturable heterotrophic populations rose continuously throughout the study, hydrocarbon utilizing bacterial and fungal populations increased up to day-90 before diminishing in contaminated soils. In order to study bioremediation of petroleum contaminated soil, petroleum contaminated soils were collected from the Zhongyuan Oil Field and microorganisms that degradate petroleum were screened from the soil. Ekundayo, E. 2004-10-05 00:00:00 EFFECT OF COMMON PESTICIDES USED IN THE NIGER DELTA BASIN OF SOUTHERN NIGERIA ON SOIL MICROBIAL POPULATIONS E. O.

Autochthonous Microbial Bioaugmented Remediation of Crude Oil Contaminated Soil in the Niger Delta. Treatment SOFM had the highest TPH reduction in soil with 66.81 % loss at degradation rate of 39.25 mg/kg/day; SO had the lowest loss of 24.82 % at the rate of 14.58 mg/kg/day within 120 days. With in defined limits biological activity increases with increasing temperature. After a period of 10 weeks, bean seeds were planted on the remediated soil to observe if these various cells would sustain plant growth for the first 15 days. This review focuses on phytoremediation with particular interest on the interactions between and use of plant – associated bacteria to restore PHC polluted sites. The survival of these plants in oil-contaminated soils indicates that they could be used for rhizoremediation in the Niger Delta. The experiment was designed to have three treatments, (1) adding microorganisms, (2) growing plants, and (3) growing plants plus adding microorganisms. Soil inoculation with constituted autochthonous microbial consortium in conjunction with NPK fertilization was effective for localized remediation of crude oil contaminated soil. Analysis of the collected data also showed that, between 1999 and 2010, 742,983,000 m3 of gas was produced, equivalent to $192 billion if harnessed and 587,375,000 m3 flared, representing $151.3 billion loss of revenue. Corresponding treatments having different number of (*) for bacteria and fungi differ significantly (n = 5, Student's t-Test, P ˂ 0.05). %PDF-1.3 %���� This review focuses on recent data relating how plant type, soil type, and soil management regime affect the microbial diversity of soil and the implication for the soil's disease suppressiveness. The results showed that combined treatment (indigenous bacteria bioaugmentation + addition of a surfactant) was the most effective method of biodegradation enhancement as the 20-fold increase of biodegradation rate was observed. Risk communication has been identified as a significant factor in explaining why the health consequences of environmental degradation remain unabated in oil producing communities. 0000007517 00000 n Results showed culturable heterotrophic and hydrocarbon-utilizing microbial populations and TPH loss in planted soils were consistently higher than those in unplanted receiving corresponding treatments (P ˂ 0.05). Nature of soil and 11. antagonistic interactions and bacteriophage, Delta State, Nigeria, at 0 to 15 cm depth, Bioremediation studies was carried out by, Soils contamination in pots were prepared. Chindah and Braide 42 in a study on the effect of oil spill on crop production in the Niger Delta reported that oil spill on crops caused great damage to the plant community due to high retention time of oil occasioned by limited flow. The natural Niger Delta environment we inherited from our forebears was an environment rich in bio diversity, varied species of wild life, dense population of marine and aquatic life, in fresh and salt water bodies, with rich mangrove and fresh water vegetation, flamboyant raffia and shrubs. Ford, C. Z., Sayler, G. S., Burlage, R. S. changes in tropical agricultural soil. Same was done for uninoculated contaminated control. Results obtained were analysed with a 2-Factor Analysis of Variance Excel tool for data analysis. culturable fungal species were identified as HUF out of the eight isolated fungi from the rhizosphere and rhizoplane The effect of water hyacinth on the remediation process had P-values greater than 0.05 at 1.5 and 3% which indicated that water hyacinth application may not be necessary for remediating crude oil contaminated soil at 1 and 3%. This paper evaluates health risk communication in the oil rich Niger Delta region of Nigeria. Petroleum exploration and production in the Nigeria’s Niger Delta region and export of oil and gas resources by the petroleum sector has substantially improved the nation’s economy over the past five decades. Food and energy supply 10. The chemical properties of spilled oil often affect the productiveness of soil and pollute water bodies, thereby causing irreparable damage to agricultural lands as well as aquatic bodies. The paper identified and analysed the major challenges posed by this crisis to the Nigerian State. Soil temperature: Temperature directly affects the activity of the soil biota by determining the rate of physiological activity such as enzyme activity and indirectly by affecting physico-chemical properties such as diffusion & solubility of nutrients, mineral weathering and evaporation rates and so on. Composition, structure and functions of microbial communities in soil are, however, under the constant control of the environment including various agricultural management practices. S = soil; SO = soil + oil; SOF = soil + oil + fertilizer; SOFM = soil + oil + fertilizer + microorganisms (hydrocarbon utilizing bacteria and fungi); SOFMS = soil + oil + fertilizer + microorganisms (hydrocarbon utilizing bacteria and fungi) + solarisation. 0000003550 00000 n Soil was monitored and evaluated for 120 days for culturable heterotrophic and hydrocarbon utilizing bacteria and fungi populations, and residual total petroleum hydrocarbon (TPH). Bioaugmentation + addition of a surfactant was applied as the combined treatment. 0000010130 00000 n The Niger Delta region is the oil producing area of Nigeria, which consists of highly diverse ecosystems that are supportive of numerous species of terrestrial and aquatic fauna and flora. Plant-associated bacteria include endophytic, phyllospheric and rhizospheric bacteria, and cooperation between these bacteria and their host plants allows for greater plant survivability and treatment outcomes in contaminated sites. Brock and Machigam [10] described soil as a complex microbial habitat with differing microorganisms. and thus, its remediation.
