The identification of an unknown bacterial environmental isolate through a series of morphological‚ physiological and differential exercises. The purpose of the environmental isolate report is to learn what is necessary in order to take an unknown environmental isolate (EI) and identify it. This was achieved through a series of exercises that provided information on the morphological‚ physiological and biochemical traits of the EI which were then compiled and interpreted in order to make a presumptive

process in which a bacterial cell takes up extracellular DNA. This can be especially useful for bacteria in order to acquire certain traits such as: antibiotic resistance‚ synthesis of catabolites‚ or any other trait that would help improve its survival. However‚ not all bacterial cells are naturally competent (able to naturally take up extracellular DNA). There are several techniques that can make cells artificially competent‚ some of which will be discussed later. Bacterial transformation was

2. Why Choose Microalgae culture or Microalgae as an Ideal biomass? Or Microalgae: advantages and disadvantages The microalgae culture have the infinite potential to be used as primary producers of biomass in coming years‚ eventually they will turn out to be as most significant energy source. They can act as feedstock for several types of renewable fuels such as ethanol‚ methanol‚ biodiesel‚ methane and hydrogen. Table 1 represents certain feedstocks used for biofuel production (Chisti 2007; Dominguez-Faus

lab experiment serves as a model for community succession using bacterial colonies as the model. A bacterial colony grows from a single bacterium and is composed of millions of cells. Each colony has distinctive colony morphology: size‚ shape‚ color‚ consistency‚ and color. Community succession is a phenomenon observed in the organizational hierarchy of all living organisms. Community succession is not limited to bacterial colonies‚ but spans the entire community of life. As the community grows

Cell size is limited by the efficiency of diffusion across the plasma membrane. A typical eukaryotic cell is 10 to 100 micrometers in diameter opposed to prokaryotic cells are 1 to 10 micrometers in diameter. Bacterial and Eukaryotic cells display different cell organization in their size and structure

Transformation of Bacterial Cells with Plasmid DNA Introduction: Transformation refers to the process in which the cell integrates foreign DNA to its genetic code‚ meaning it takes the genes and incorporates them into the cell’s current DNA. Cells that can do this naturally‚ most commonly bacteria and archea‚ are known as competent. The bacteria E. coli do not have high transformation competence under normal conditions‚ but can be manipulated to produce better results using

Biology101 McDowall 10/29/2012 Escherichia Coli “The Bacterial Beast” E.coli or binomial name Escherichia coli was discovered by a German pediatrician named Theodore Escherich in 1885. Dr. Escherich originally named the bacteria‚ bacillus communis coli. After the demise of Dr. Escherich the intestinal bacteria was then named Escherichia coli after the late doctor in 1919. The bacteria Escherichia coli are classified as follows. Domain- Bacteria Kingdom- Eubacteria Phylum- Proteobacteria

“Jamestown Colony” On May 14‚ 1607‚ a group of colonists from England arrived in the New World and formed a settlement in the Colony of Virginia. In the winter of 1609-1610‚ all but 60 of the 900 colonists died due to their mistakes. The settlers came to the New World unprepared‚ expecting to be able to trade with the Natives for food and supplies‚ but eventually were not able to. Overall‚ the settlement failed due to its dependency on outside resources and lack of skills needed to make a settlement

The Great Awakening and the Enlightenment sparked new ideas that lead to important documents such as The Declaration of Independence‚ The Constitution‚ and The Bill of Rights. The Great Awakening swept through the colonies in the 1730s and 1740s. It was a turning point back to religion and away from secular worldly views. People such as Jonathan Edwards George Whitefield presented a new Fire and Brimstone style of preaching. the difference between Old Lights and New
