member used a pipet to gather a small amount of spore suspension. He squeezed the liquid in and out several times‚ before depositing 3 drops onto the agar solution in a petri dish. Next‚ another group member used an alcohol wipe to sterilize the spore spreader. It was necessary to ensure no contamination of the spores. He then proceeded to distribute the spores around the dish and solution. After sealing the petri dish back up‚ I labeled the dish with our group name and date. Finally‚ the petri dish

How to clean dishes properly There are two ways to wash your dishes: by hand or in the dishwasher. Even though they both give the same results‚ there seems to be a disagreement about which is better. Some prefer the dishwasher for its convenience‚ and others prefer hand washing because you can control how much water you use and ensure that your dishes are clean the first time. To wash dishes by hand‚ first make sure you use the hottest water that you can without making it so hot that you burn

Lab Report - Microbes Aim: To investigate four areas of the school and to find out which of the four have the most microbes. Areas to Sample: 1. Girl’s locker room (Senior school) 2. Girl’s locker room (Elementary school) 3. Boy’s locker room (Senior school) 4. Boy’s locker room (Elementary school) Hypothesis: We predict that the boy’s locker room in the senior school will have the most microbes. First of all‚ there are more people using our locker rooms in the Senior School

MANIPULATION OF BACTERIA INTRODUCTION: In this experiment that we performed‚ there were many methods that were used to help us manipulate and identify the bacteria E.coli on a MacConkey agar plate. The first part of the experiment involved the methods of manipulating‚ identifying and counting the bacteria and the second part was to find out whether the bacteria E.coli was the only type found in the given area by gram staining. E.coli was the chosen bacteria for this type of experiment. It is

Virus and Bacteria Virus - A virus is a capsule of protein that contains genetic material. A virus cannot reproduce on its own; it must infect a living cell to grow. Bacteria - Bacteria are one-celled organisms that live on their own. They can multiply and reproduce by subdivision Bacteria and viruses cause many of the diseases we are familiar with and may sound synonymous; they are greatly different from each other. [pic] o They differ greatly in size. The biggest viruses are only as large

Microorganisms can be prokaryotic—the bacteria or eukaryotic—the algae‚ protozoa or fungi. While viruses are acellular they are also studied in the scope of microbiology because they are small and because they infect cells. While most bacterial are unicellular they can also exist in colonial or multicellular forms. In this laboratory exercise you will examine the ubiquity and diversity of various microbes that are present in the environment or inhabit the human body. Most bacteria that inhabit the body are

CHAPTER TWO Beneficial bacteria in the environment and their uses. In today’s world‚ the environment and its related issues are steadily gaining a lot of importance. Some bacteria are helpful and are used to obtain balance in the environment. It has been seen that helpful bacteria are useful in dissolving organic sludge from water‚ breaking down the growth of algae‚ reducing the various noxious odours such as hydrogen sulfide odours‚ reducing ammonia levels‚ promoting faster growth of fish in the

Antibiotics attack bacteria by targeting a protein‚ or stopping the creation of a cell wall and or how they metabolize sugar. This method of targeting the specific functions of bacteria have allowed antibiotics like Penicillin to save millions of live throughout in the past few decades. As amazing as antibiotics are they have a really smart enemy. Bacteria are cleaver little single-celled organisms. Bacteria can actually barf up the antibiotics we use to fight them. The genetic information bacteria gather in

microorganisms in our planet‚ bacteria. Bacteria lives everywhere‚ in air‚ hot springs‚ and in our bodies. Some bacteria are harmful and some of them are helpful. Biologists use helpful bacteria in several ways. In my essay‚ I will focus on some uses of bacteria in medicine‚ environment‚ and industrial. Bacteria contains many distinctive characteristics that makes it very important for the environment. It is considered one of the basic decomposers in the environment because bacteria analyzes dead organisms
