Mystery bacterium I would not say science is storybook fun‚ but who knew it become a mystery. Trying to find out what was in our number seven vial would become a battle we were willing to take on. As I began the test of deciding if our little bacteria friend was gram positive or negative‚ Jordan my science teammate‚ was putting together a smear plate. In as little as ten minutes we had discovered by the pink oval shapes we were observing‚ our microbe friend was a gram negative rod. We had narrowed

A gram-negative bacteria like Escherichia coli protect its cells from stresses that cause the misfolding of proteins‚ which are later secreted across the cytoplasmic membrane (Raivio et al.‚ 2013). In response to the secretion of misfolded proteins‚ gram-negative bacteria use two major envelope stress responses (Raivio et al.‚ 2013). One of the envelope stress responses is the Cpx envelope stress response and it is activated by a diverse set of inducing signals‚ such as alkaline pH‚ chloride ions

The purpose of the following study is to determine where the two unknown bacteria acquired in Microbiology lab should be classified in regards to temperature‚ pH level‚ and osmoregularity. It is important to classify bacteria in order to identify them. Identification of bacteria is important because they are not only useful but potentially dangerous as well. The identification of bacteria can lead to breakthroughs in healthcare regarding treatment of old and new diseases alike. Identifying bacteria

Taxonomy ultimately comes down to questions of origins. Some of the beginning of certain groups is surprisingly straightforward. Some involved steady adoptions to solely changing environment and conditions. In other situations dramatic changed in the conditions seem to force sudden and noteworthy changes to the evolution. And sometimes‚ a gigantic event makes a big splash in evolution. The origin of eukaryotes appears to have been a big splash in the form of endosymbiosis‚ a condition in which different

Halobacterium Lab Investigation Mason Pirio 12/12/13 Period 5 Table Group 3 PS 2- Experiment Design PS 3- Conclusion Writing PS 13- Nitrogen Cycle Abstract- In this experiment we tested to see how well halobacterium grows in different levels of salinity. We found out that the higher salinity in the growth medium the better the halobacterium grows. Background Information- Halobacterium is a bacteria that is found in the great salt lake. Halobacterium is an extremeophile which means it thrives

1. A functional cell could be built with a single chromosome‚cytoplasm‚a cell membrane‚ and ribosomes.Why are these four components absolutely necessary to the functional cell? If these structures are all a cell needs‚ why do most cells have many more structures? A chromosome is necessary so that there is a “map” of the cells function and structure‚ cytoplasm is necessary as it is where most of the cell’s activity occurs‚ ribosomes are essential as they are the site of protein synthesis‚ which

Lab 10: Cell Structure & Function Questions 1. For each structure identified‚ do you think its location affects its ability to function? Why or why not? (Hint: those buried deep in the cell probably do different things than those closer to the cell membrane) Structure does not affect function of the cells‚ cells have a particular structure that enables them to carry out their function in the best way. Everything in a cell is there to enable it to perform in the most efficient manner possible

Contagious Bovine Pleuropneumonia (CBPP) What is CBPP and what causes it? Contagious bovine pleuropneumonia (plur-OH-new-MOAN-ya)‚ or CBPP‚ is an easily spread respiratory disease of cattle. It is caused by the bacteria Mycoplasma mycoides mycoides (my-COplaz- MA my-COYdees)‚ a similar but different organism than Mycoplasma bovis‚ the bacterium associated with mastitis and shipping fever in cattle. Contagious bovine pleuropneumonia is a serious disease in Africa causing death rates of up to 80%.

Bacterial Diversity Project John FreesackSection A24 Kim Daffer‚ John Chang September 23‚ 2012 Introduction: Bacteria are everywhere. Some can be seen with the naked eye and some require a microscope but how do we distinguish one kind of bacteria from another? To answer this question‚ we were required to complete three bacterial labs that helped us to understand what microorganisms are and how to identify and classify them. Thus‚ the main purpose of this project is to identify our unknown microorganisms
