The Effect of Metal Ions on Lichens Casey Stinnett ESC 1510 October 30‚ 2014 Introduction Lichens are a sybiotic association of fungus (mycobiont) and algae (Pediastrum boryanum . The fungus engulfs the algae‚ then supplies carbs‚ nitrogen‚ and vitamins while the algae photosynthesizes. This unusual relationship enables the lichen to grow in environments where neither fungus nor algae would normally be able to solely survive. They are found on every continent‚ ranging all the way from

can survive in extreme environments. Halobacteria are also useful by being a good organism to perform DNA transcription‚ translation‚ and transformation on (Kramer‚ 2006). There are two different types of Halobacteria that are being observed in this lab. The first is NRC-1‚ which is also called the wild type strain. Although the pigmentation of the Halobacteria is caused by the production of the membrane protein‚ bacteriorhodopsin‚ which is a red‚ the wild type strain is pink in color. This pink color

Isolation of Bacteria in our Physical Environment Introduction: The purpose of the lab is to apply what has been learned so far in Microbiology‚ and use it to collect and examine microbial species from the physical environment. The physical environment around the lab will be utilized to find out the variety of different microbial species growing in and around the lab. This investigation will help in preparation for the individual projects that will be done at the end of the semester. Materials

Enzyme Lab Using Jello INTRODUCTION: Enzymes are known as protein catalysts. The name protein catalyst suggests that most enzymes are made of proteins. A catalyst is a substance that speeds up chemical reactions without being consumed in the process. (Giuseppe‚ M 2002‚ p.69). After a reaction has been catalyzed‚ the catalyst can be used again to catalyze the same reaction. Enzymes reduce the activation energy (minimal energy) it takes for a reaction to take place. Enzymes can either catabolize

organism” (Simpson‚2010). Fermentation is the metabolic procedure in which an organism alters a carbohydrate‚ such as sugar or starch‚ into an acid or alcohol. For instance ‚ yeast performs fermentation to achieve energy by altering sugar into alcohol. Bacteria execute fermentation‚ altering carbohydrates into lactic acid (Helmenstine‚ 2013). Fermentation can be used in the food and drink industry as well‚ examples of this is bread. In the process of fermentation with bread‚ yeast produces carbon dioxide
