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

1. What is the difference between a. and a. Summarize the meaning of “federalism” in your own words. Federalism is a governmental structure that allocates authority between a national government and smaller entities‚ like states or provinces. In the United States‚ this means that certain powers are delegated to the federal government‚ while others are reserved for the states. This means that the federal government holds certain powers‚ while other responsibilities are given to individual states.

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
