some people see bacteria as something that is harmful and that causes nothing but illness and infections. Bacteria can actually be helpful as well. It can provide vitamins to your body‚ help digestion‚ destroy bad organisms‚ help make medicines and also help out with the environment. In this research paper‚ it will describe two bacteria that are helpful and sometimes harmful to humans and the environment‚ which are E. coli and Lactobacillus Acidophilus. E. coli E. coli is the bacteria that live in

resistance occurs when an antibiotic is no longer effective against a particular bacteria‚ making that organism resistant to the effects of the antibiotic. Bacteria become resistant due to selective pressure. Those organisms which resist the antibiotic‚ and do not die from it ’s effects have a greater chance of survival within the host‚ therefore allowing them to reproduce and spread it ’s resistance to other bacteria. while the ones susceptible to the antibiotics die. This can be caused by unnecessary

Abstract Some bacteria are able to go through transformation making new combinations of genes. Transformation is a way of gene variability in bacteria. This experiment is based on the transformation mechanism of bacteria and gene regulation. The bacteria used for the experiment was Escherichia coli and the genes introduces for the transformation were: gfp and bla by a pGLO™ plasmid. After the insertion of the target genes and growing the bacteria on specialized LB media‚ it could be seen that the

Lecture 14 Lecture Gene Complementation in Bacteria In order to perform tests for dominance or for complementation in bacteria we need a way to make the bacteria diploid for part of the chromosome. To do this we need to consider a different extrachromosomal element: Ori T The F plasmid (length 105 base pairs) Tra genes There are some special terms to describe the state of F in a cell: F– refers to a strain without any form of F‚ whereas F+ refers to a strain with an F plasmid. F‚

Question: Suppose a meteor impact blows some extremophile bacteria from the Earth into the depths of a gas giant planet called planet X ‚ where they evolve into an intelligent species which practises physics. Do you think their physical theories would be similar to ours‚ and if so in what ways would they be likely to be similar? Your answer will necessarily involve some speculation‚ but make sure it involves some careful argument as well. Theoretical physics is one of many braches of physics that

Application of lactic acid bacteria There are four major categories for the current uses and applications of LAB: food‚ cosmetic‚ pharmaceutical‚ and chemical applications. In food industry Recent years the interest increased in using LAB by using bacteriocin-like inhibitory substances (BLIS) because of their potential use as a natural antimicrobial agent to enhance the food safety of food products and increase the nutritional values of the food. Foods that fermented by LAB such as cheese
