“…They also affect the biological properties of the soil by modifying the populations of particular microorganisms. This, in turn, affects the soil enzymatic activity (Wyszkowska and Kucharski 2001, Budny et al 2002, Delille and Pelletier 2002, Wyszkowska et al 2002a, b, Caravaca and Rodán 2003 and the content of assimilable macro-and microelement forms in it. Under such conditions, the take up of macroelements by plants changes and their content in particular plant organs fluctuates ).…”

The aim of the study was to determine the effect of soil contamination with diesel oil (3, 6, 9, 12 and 24 g/kg soil) on the yield and the content of macroelements in oat and maize cultivated in soil supplemented with nitrogen and sawdust. The correlation between the content of macroelements in the crops and the soil enzymatic activity was also determined. High doses of diesel oil had a definite negative effect on the content of all macroelements in oat, excluding phosphorus. The presence of diesel oil had a favourable effect on the accumulation of most of macroelements in the above-ground parts of maize. Nitrogen application to the soil caused an increase in the content of nitrogen and in the accumulation of calcium and magnesium in the above-ground parts of both crops as well as an increase in sodium content in maize. Sawdust applied to the soil had a considerably lower effect (several to less than 20%) on the content of macroelements in plants. A correlation between the activity of urease and acid and alkaline phosphatase in the soil and the content of macroelements in plants cultivated in diesel oil contaminated soil was observed. This correlation was positive only in the case of alkaline phosphatase activity and phosphorus content in oats.

“…Hydrocarbon oil spills in terrestrial regions widely affect the microbial population in the topsoil (Bundy et al, 2002) and deeper soil regions (Krumholz, 1998). The nutrient cycle of subsurface soil environments is mainly disrupted by the decrease in microbial activity, affecting the recycling of macro nutrients, affecting the oxygen availability to microorganisms (Krumholz, 1998).…”

-Two bacteria, namely Bacillus subtilis and Pseudomonas aeruginosa were exposed to different concentrations of diesel to increase their adaptation to the fossil fuel, and were used for the degradation of diesel-biodiesel blends. The biodegradation rate was evaluated using the redox indicator 2,6-dichlorophenol indophenol (DCPIP) test and gravimetric analysis. The preliminary exposure of cells to diesel proved to improve their biodegradation capacities, and exposure to a higher concentration (70%) of diesel resulted in maximum biodegradation of up to 58.38 g and 1.78 g of degraded oil per CFU/mL (10 10 ) for P. aeruginosa and B. subtilis respectively. It was found that the adapted cells preferably used diesel in the blend. P. aeruginosa and B. subtilis exhibited different adaptation capabilities and biodegradation behaviour. Biodiesel stimulated the biodegradation of the diesel-biodiesel blends by non-adapted cells only; the adapted cells exhibited a different behaviour.

“…En consecuencia, el entendimiento de la ecología microbiana y las restricciones de la biodegradación de un suelo contaminado con petróleo es extremadamente importante (Bundy, et al, 2001). Por lo tanto, la bioestimulación de la población microbiana indígena, puede acelerar el proceso de biodegradación de los contaminantes (Bento, et al, 2005).…”

“…Con respecto a la influencia de la estructura del suelo, en la biorremediación de suelos contaminados por hidrocarburos, existen varias publicaciones que han estudiado su influencia, principalmente basados en las diferentes tasas de biodegradación presentadas cuando varía el contenido de los tamaños de partículas que constituyen el suelo y de las agregaciones que están pueden producir (Young-Gyun, et al, 2000;Bronick, et al, 2005;Bento, et al, 2005;Baek, et al, 2004;Bundy, et al, 2001;Amellal, et al, 2001;Sessitsch, et al, 2001) coincidiendo que la textura juega un papel importante en la biodisponibiidad del hidrocarburo a ser metabolizado, disminuyen los porcentajes de biodegradación conforme aumenta la cantidad de partículas finas pero que existen otros factores que también influyen y que se los ha comentado a lo largo de este apartado.…”
