government who will keep our water unpolluted and free of bacteria and other germs?Do people need government? By: Arianna McCoy In my view people do need government because the government does a lot of things they don’t get recognition for. For example‚ they keep our water fresh. The government makes large investments to keep our drinking water safe. Without the government who will keep our water unpolluted and free of bacteria and other germs?Do people need government?

Unknown Bacteria: Bacillus cereus Brittany Moy Coastline Community College Abstract Bacillus cereus is a Gram-positive‚ facultative aerobic‚ spore-forming‚ rod-shaped bacterium that is widely distributed among the environment. Introduction The reason for identification of unknown bacteria was to help students recognize different bacteria through different biochemical tests and characteristics. This is important in the medical field because identification of unknown bacteria can help

to classify bacteria through their chemical nature as well as the physical structure of their cell walls. Through this experiment one would be able to observe either a thick or thin layer of peptidoglycan by the appearance of the bacteria staining either gram-positive blue-purple or gram-negative pink. Question: Is there a subsequent effect of the bacteria when decolorizing with alcohol? Hypothesis: If there is either a removal of the outer cell membrane or dehydration of the bacteria then there

and classify bacteria‚ it is a differential stain that allows you to classify bacteria as either gram-positive or gram-negative. The foloowing is a breif summerary of the gram staining procedure. Apply the primary stain Apply Mordant Apply decolorizing agent Apply the secondary stain Bacteria that lose color easily after decolorization are referred to as gram-negative‚ and bacteria that retain the color from the primary stain is called gram-positive. Bacteria stain differently

Unknown Lab Report April 25th‚ 2006 Introduction The purpose of this lab was to identify two unknown bacteria cultures using various differential tests. The identification of these unknown cultures was accomplished by separating and differentiating possible bacteria based on specific biochemical characteristics. Whether the tests performed identified specific enzymatic reactions or metabolic pathways‚ each was used in a way to help recognize those specifics and identify the unknown cultures

Title Antimicrobial properties in different type of plants. Introduction A substance that kills or prevents the growth of microorganisms for example bacteria‚ fungi or protozoans is called an antimicrobial. This substance has 2 major roles which are to either kill microbes (microbiocidal) or prevent the growth of microbes (microbiostatic). Disinfectants are antimicrobial substances used on non-living objects outside the body. This substance included antibiotics‚ antifungals‚ antiprotozoals and

Staying on the topic of food‚ the process of fermentation requires the use of bacteria which is a microbe. A big example of this is the production of bread which uses yeast to make the bread rise. This works as it is aerobic respiration so gives off carbon dioxide‚ making the bread rise. Another use of yeast is in anaerobic respiration

It spreads faster because of how common it has become to go out and eat. It is too late to stop the bacteria from spreading after the contaminated food is sent to the restaurants and spread throughout the community (“Food
