Bacterial growth patterns and the effects of environmental factors on properties of colonies ERIC LI Abstract In this experiment we work with different types of bacteria and experiment with their different properties and how they grow in certain situations. Different samples of bacteria cultures were gathered from different places such as the mouth‚ shaded mulch‚ and from the table top. The samples were collected by using a cotton swab and swiped onto a petri dish filled with nutrient agar. The

David Kennedy Bio 210 Lab Report 1 10/11/13 Microbial Growth Background Information: This lab was conducted in order to understand basic differences among differential and selective media‚ while recognizing how each media is used to isolate and identify microorganisms (Wistreich‚ 2003). The first microorganism analyzed was Staphylococcus epidermidis. This organism is gram-positive‚ single celled‚ arranged in grape-like clusters‚ and cocci in shape (Bukhari‚ 2004). S. epidermidis is approximately

Research Plan Research Question: What is the antimicrobial effect of common household spices/herbs such as cinnamon‚ cloves‚ mustard‚ ginger‚ and garlic‚ on the zone of inhibition in the Staphylococcus epidermis covered nutrient agar? Hypothesis: If 3 teaspoons of chopped cinnamon‚ cloves‚ mustard‚ ginger‚ and garlic steep in half a cup of boiling water for 15 hours and then placed in nutrient agar covered with Staphylococcus epidermis (gram positive) bacteria for 24 hours (in an incubator)‚ garlic

Medium of exchange is what a buyer uses to purchase either a good or service from a seller‚ in most cases this is going to be money. Money is an accepted medium of exchange because we know that we will be able to obtain goods and services if we have the money to purchase them. Unit of account is used to measure and record economic value. This means that we use this when the amounts will be measured in dollars and not the quantity of goods. The store of value is when someone will keep the money that

The medium is the message. McLuhan tells us that a "message" is‚ "the change of scale or pace or pattern" that a new invention or innovation "introduces into human affairs." He always encouraged other people to look behind the scene and understand it. Here we consider example of theatrical productions. In general the message from these productions is not their music and plays but the tourism which means people travel more and more to see such kind of shows. On the other hand if we talk about

The Medium is the Message” The medium is the message is a phrase that challenges the idea behind the artwork‚ which was coined by Marshall McLuhan. McLuhan warns us that we are often distracted by the content of a medium. The true value of a medium is how can it be used to enhance our collective experience and understanding within society. It can discuss the meaning that the form of a medium embeds itself in the message‚ creating a symbiotic relationship by which the medium influences how the

What is the Meaning of The Medium is the Message? by Mark Federman Former Chief Strategist McLuhan Program in Culture and Technology a culture like ours‚ long accustomed to splitting and dividing all things as a means of control‚ it is sometimes a bit of a shock to be reminded that‚ in operational and practical fact‚ the medium is the message. This is merely to say that the personal and social consequences of any medium - that is‚ of any extension of ourselves - result from the new scale that is

After each streak‚ the inoculation loop need to heated. The plate was keep for 24 hour at temperature of 30ºC for colony growth. b) Sequestration of bacteria from shrimp Methodology Dissecting set was prepared and soaks it in a beaker that contains 70% alcohol.

Microbiology Module 02 Homework Assignment Use the information presented in this module along with additional outside research to answer the questions: 1) Compare and contrast prokaryotic and eukaryotic. a) Prokaryotes and eukaryotes are two types of cells that are very different but share some certain properties such as methods of reproduction‚ protein synthesis‚ an organized metabolism‚ response to stimuli‚ and plasma membranes. One significant difference is that prokaryotes are without a cell
