microorganisms isolated from garage soil (petroleum contaminated soil) was studied. Modified diesel engine oil medium was used and two most abundant microorganisms were isolated from garage soil – Micrococcus sp. and Pseudomonas sp. were found to be hydrocarbon degraders and these two bacteria’s were selected for the degradation test. The degradation of diesel engine oil was monitored at a five day interval up to twenty five day period‚ using gravimetric method. After 25 days of incubation period‚ Pseudomonas

Chemistry Unit 1 – Revision Questions Chemistry 1A 1) Define an element. How many are there in the Periodic Table? 2) Write a table with the charges and masses of protons‚ neutrons and electrons. 3) Define atomic number and mass number. 4) Draw electron (energy level) diagrams for Be‚ S‚ Al‚ Cl and K. Also‚ write down the number of protons and neutrons for each. Finally‚ write the symbols (with mass no. and atomic no.) 5) Why have all Group 7 elements (halogens) got similar chemical properties

PROPERTIES OF HYDROCARBONS Introduction Hydrocarbons are compounds which contain only carbon and hydrogen‚ can be classified into several types‚ depending on their structure. Aliphatic hydrocarbons are divided into three classes: alkanes (e.g. methane‚ ethane and propane) have only single bonds‚ and are said to be saturated; alkenes (e.g. ethene and propene) and alkynes (e.g. ethyne) have carbon-carbon double or triple bonds‚ and are said to be unsaturated. Aromatic hydrocarbons are cyclic compounds

Hydraulic Fracturing “Fracking‚” or hydraulic fracturing‚ is a controversial technology that was originally developed over 60 years ago. It allows us to obtain oil and hydrocarbons from otherwise inaccessible underground locations by drilling thousands of feet into the Earth and intentionally fracturing the shale. The oils and hydrocarbons are collected and then refined into pipeline quality natural gas. Natural gas is cleaner‚ more reliable‚ and more abundant than other fossil fuels. In recent years

When the Deep water Horizon had blown up there were pollutants that were released into the water and into the air. In the air it consisted of smoke and hydrocarbon fumes. The water was polluted with oil out of the rig and there were now dead sea animals that were spread threw out the Gulf of Mexico after the rig had spilled. The smoke and the hydrocarbon fumes were pollutants and that means that they are the kind of pollutants that are put into the air directly from where it was coming from (Hager &

This paper contains an extensive review of the three main groups of catalysts‚ which have been estimated for the elimination of these hydrocarbons. These three groups of catalysts are dolomite‚ alkali metals and nickel. Keywords.

to stick to itself and more likely to interact with oil and grease. Soaps are sodium or potassium fatty acids salts‚ produced from the hydrolysis of fats in a chemical reaction called saponification. Each soap molecule has a long hydrocarbon chain‚ sometimes called its ’tail ’‚ with a carboxylate ’head ’. In water‚ the sodium or potassium ions float free‚ leaving a negatively-charged head. Soap is an excellent cleanser because of its ability to act as an emulsifying agent. An emulsifier
