But in addition many bacteria are able to modify hazardous chemicals, transforming them into other less toxic. Thus, some bacteria can reduce the bioavailability (make it less accessible and therefore less toxic) heavy metals such as mercury, arsenic, chromium, cadmium, zinc or copper. Likewise, the isolated microorganisms in soils are peroxidases and oxygenases activities that allow the oxidation of some petroleum fractions. This oxidation changes the properties of the compounds making them susceptible to secondary attacks and facilitating their conversion to carbon dioxide and water .. Follow others, such as Bill de Blasio, and add to your knowledge base. 6.2 Feasibility After degradation of soil contamination with hydrocarbons concentrations of hydrocarbons are subject to evaporation, dissolution in contact with the soil water altered by photolysis, or subject to biodegradation. The latter considered that the upper layer of uncontaminated soil with adequate carbon, oxygen and nutrients can contain between 107 and 109 organisms per gram total; of these, 0.1 to 1.0% can be hydrocarbon degraders, however the soil conditions do require humidity, oxygen and nutrients for their achievement. More than one hundred thirty genera microbial species are capable of using hydrocarbons as a means of subsistence.

"Oil is a source of carbon, is a nutrient," says Victor de Lorenzo. What to us is a toxic element for bacteria is a source of food. They have an enormous metabolic capacity, 6.3 Common forms of waste oil The drilling of wells with "dry lease" without sink. Is to use special equipment for sludge treatment, making more efficient use of them to better separate the liquid from the solid phase, bringing the final volume of the latter is substantially reduced and facilitates the processing and disposal of both phases.
