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

Enumeration of Bacterial Contamination in Hamburger Meat from Unknown Sources C March 6‚ 2012 The importance of bacterial enumeration has become even more apparent in recent years due to the increasing numbers of harmful bacteria found in meat products. This process is the key to understanding the populations of microorganisms that contaminate the food supply. Much of the bacteria in meat has been shown to be resistant to multiple drugs; so disease-causing microbes

Project Title: Examination of bacterial content of sea water samples from selected sites in South East England Introduction Over the past few years coastal beaches across the UK has seen lavished with recognition for their cleanliness‚ by sections of the media and various organisarions. Majority of these beaches have been awarded the Blue flag award in recognition for meeting set criteria on various standard including cleanliness‚ water quality‚ environmental management and environmental education

Cristina Alzandua General Biology 1401 Dr. Erin Schuenzel February 13‚ 2014 Bacterial and Eukaryotic Cell Structures All organisms are composed of cells which are characteristically microscope in size. 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

MORPHOLOGY MARTOS ALFITRI PBI V D 10714000764 Morphology Morphology is the study of the construction of words out of morphemes Morpheme The morpheme is the smallest meaningful unit of language. (lexical and grammatical meaning) A morpheme must have a meaning‚ and it is the smallest unit of meaning (the smallest sound-meaning union which cannot be further analyzed into smaller units). The word lady can be divided into two syllables (la.dy)‚ but it consists of just one

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

Behavior vs. Morphology on Ectotherm body temperature Introduction: Endotherms are organisms that maintain a stable body temperature. The environment has little effect. Endotherms consume different resources to maintain a stable body temperature trough changes in their metabolism. Ectotherms are organisms that cannot maintain a stable body temperature on their own. Ectotherms depend on its environmental surroundings to stabilize its body temperature. Stabile body temperatures are very important

OBSERVATION OF BACTERIAL CELLS VIA MICROSCOPE In this experiment‚ we have learned several basic molecular biology techniques. Here they are; Simple staining: Only one type of dye used for simple staining and it stains all cells the same color. Creating contrast between cell and background to observe cell morphology is aimed. Differential staining: A differential stain uses more than one dye and stains different kinds of organism with different colors. Positive staining: If cell itself is stained
