rhamnolipid biosurfactants on the first-order biodegradation rate constant for a microbial consortium growing on a mixture of hydrocarbons representing four structural classes of hydrocarbons. The microbial biodegradation rate of hexadecane‚ dodecane‚ benzene‚ toluene‚ iso-octane‚ pristane (2‚6‚10‚14 tetramethyl pentadecane)‚ naphthalene‚ and phenanthrene in the presence and absence of a mixture of rhamnolipid biosurfactant was determined. A first-order biodegradation model was applied in these studies

Biodegradation OF Xenobiotics . OVERVIEW Microorganisms play an important role in the removal of synthetic organic compounds from the environment. This chapter gives an overview of the evolution of biodegradation pathways and describes the strategies that microorganisms have evolved to transform important molecular structures. The actual effectiveness of biodegradation in the environment is determined by the bioavailability of the

Kirat Hundle 1. What is the difference between an element and a compound? An element is an isotope made of the number of neutrons it has. A compound is a substance made of two or more different elements (a mixture). 2. What is the periodic table? A periodic table is where the chemical elements are organized based on their atomic number (number of protons in the nucleus)‚ electron arrangement‚ and chemical properties. 3. Give two examples of each of the four major mineral groups (silicates‚ carbonates

FACTORS AFFECTING SULFUR MINERALIZATION Sulfur content of organic matter Mineralization of sulfur depends on the sulfur content of the decomposing material in much the same way that nitrogen mineralization depends on the nitrogen content. Smaller amounts of S042- are liberated from low sulfur containing residue‚ which is similar to nitrogen mineralization. At or below a C/S ratio of approximately 200/1 only mineralization of sulfur occurs. Source of mineralizable sulfur Because of the contribution

What is the difference between the phases of internationalization and of globalization? Internationalization and Globalization are two terms that are often assimilated and sometimes used as synonyms. This is a mistake because these terms have many differences‚ starting with the time they began to occur. Internationalization started as part if the Industrial Revolution between 1870 and 1914‚ whereas globalization is a post 1960’s phenomenon. Other differences between these two terms include their

For example‚ economics‚ religion‚ government‚ and politics shared some similarities but also some differences did occur as well. Economically the North and the South were similar in a few ways. “Squatting was a way of life among the

Revolution brought about significant changes‚ both within the United States and globally. Some of the key changes include: 1. What is the difference between a. and a. **Independence**: The most obvious change was that the thirteen American colonies gained independence from British rule. This established the United States as a sovereign nation. 2. What is the difference between a’smart’ and a’smart’? **Political Systems**: The Revolution led to the creation of a new government system based on democratic

What is the Difference between Intranet and Extranet? Intranets and extranets are network systems that are used to maximize business productivity. In this case the intranet would be the macro-system and the extranet would be the micro-system. When I think about intranet I think of a business’s personal World Wide Web; although it is not the internet it still has more resources and capabilities than the extranet. One way to look at it is to think on a scale of private and non-private. The intranet

What’s the difference between myths and theories? Well that’s an easy question to answer isn’t it; myths involve fiction while theories involve facts‚ we should not make any parallels between science and superstition. There‚ we’ve answered the question‚ or have we? Although many people will agree that myth and theory are two totally different things‚ I would debate that the line between the two is much thinner than one would think. In fact in some cases the line is inexistent and myths make up theory
