“…Okere et al (2012) investigated the natural attenuation potential of indigenous microorganisms on Livingstone Island, Antarctica, for degradation of 14 C-labelled phenanthrene at 4, 12 and 228C. The results provided evidence of evaporation but little biodegradation at 48C, consistent with previous findings (Snape et al 2005;Snape et al 2006;Revill et al 2007;Dias et al 2012). However, the addition of nitrogen, peaking in the range 1000Á1600 mg N kg-soil-H 2 O (1 enhanced the mineralization of 14 C-octadecane in soils from Old Casey Station, Antarctica (Ferguson et al 2003).…”

“…Biostimulation of indigenous soil microorganisms through nutrient addition and optimization of environmental conditions such as oxygen content, pH and temperature has been well reported in cold regions (Delille et al 2003;Walworth et al 2007;Das & Chandran 2011;Dias et al 2012;Mair et al 2013). In the Antarctic, limited nitrogen, cold temperatures and water availability contribute to significantly slower degradation rates of total petroleum hydrocarbons (TPH), relative to temperate regions (Ferguson et al 2003;Walworth et al 2007).…”

“…There were also appreciable levels of other trace elements. With mean of 0.05%, the TOC level of test soil was less than 12% reported for soils derived from mineral sources (Dias et al, 2012) [18] and is in consistent with findings of previous reports on the study area (Adesua, 2014) [6]. However, contamination of test soil increased the TOC of the soil to range of o.14 -0.21%, the TON was reduced from 0.39 to 0.21 -0.28 depending on the level of contamination.…”

“…The particle size arrangement of soil determines the texture of the soil, while soil texture determines the water absorption capacity, water storage, ease of tilling as well as soil aeration and fertility (Dias et al, 2012) [18]. The pH range of 5.67 revealed a strongly acid soil and acid soils are known to exhibit intensive leaching, low exchangeable basic cations content and slow microbial activity (Adesua, 2014) [6].…”

Land contamination with crude oil is one of the challenges of effective crop production in the Niger Delta Region of Nigeria. This condition is inherent thus creates the need for developing effective remedial methods of managing contaminated lands as well as improve crop production. This study was designed to assess the effect of Brewers Spent Grains (BSG) on microbial activities and growth of Capsicum annum L cultured in crude oil contaminated soil. The results have shown that depending on the level of contamination, crude affected both the physical and chemical attributes of soil. It increased the acidity from pH 5.67 to a range of 5.58 -5.64 and the total organic carbon content from 0.05% to 0.14% -0.21 while the total nitrogen and available phosphorus levels of soil were remarkably reduced from 0.39% to 0.21% -0.28%, and from 0.036% to 0.028% -0.032% respectively. Amendment of contaminated soil with BSG had variable influence on the microbial properties of test soil. It increases the heterotrophic activity of bacteria in soil while retarding the activities of nitrogen fixing bacteria (Nitrosomonas sp and Nitrobacter sp). However at a stimulating amendment level of 150g of BSG in a 0.208% level of contamination, the activities of hydrocarbon degrading bacteria was enhanced from the hitherto low number of 3.6 log CFU/g found in test soil to 6.2 log CFU/g obtained on the 6th week of the remediation period. This resulted in 62.09% hydrocarbon degradation in soil at the end of the 8-week remediation course. BSG amendment of the oil contaminated had clear but variable influence on some agronomic traits of the cultured pepper. Growth was generally promoted by the amendment and the most significant (P<0.05) growth attributes affected were the plant height, number of branches, leaves, flowers and fruits as well as the leaf area. Pepper seedlings exposed to 0.624% of oil and remedied with 300g (1.5%) had the highest number of flowers but the flower did develop into fruits. However plant exposed to 0.416% of oil contamination and remedied with 0.75% of BSG produced flowers that formed fruits. Although the cultured pepper plants exhibited necrotic spots, this study has shown that plants grow in crude oil contaminated soil if alternative source of nutrients is provided. This tend to grow more in lightly contaminated soil and remediation using BSG has proven to enhance the activities of microorganisms and subsequent degradation of hydrocarbons in contaminated soil. It is highly recommended for use as soil conditioner to "unmask" nutrients in contaminated soils.

“…Estos pueden determinar un ambiente ácido o alcalino en la fase líquida e influir en el desarrollo de especies microbianas capaces de degradar los hidrocarburos adsorbidos en los poros del suelo. Dias et al (2012) han reportado relaciones de nutrientes esenciales C:N:P (100:10:1) en la fase líquida del suelo que mejoran el pH, es decir que lo incrementan de 5 a 7 y con ello, se favorece un crecimiento microbiano eficiente que promueve la biodegradación de los hidrocarburos intemperizados. Por consiguiente, se deben de considerar todas las fuentes de nutrientes que afectan los procesos metabólicos así como el tipo de fracción mineral o arcilla y los contaminantes presentes en el suelo.…”

The weathered hydrocarbons are mainly constituted of highly persistent heavy petroleum fractions. Thus, the soil chemical complexity delays the hydrocarbon biodegradation. The objective of this study was to increase the bioavailability of highly persistent compounds by obtaining the greatest nutritional conditions for indigenous microorganisms. A consortium was previously adapted in order to achieve the full potential of degradation through the biostimulation process which was carried out by the Plackett-Burman
