There are two independent variables in this experiment which are the brand of dishwashing detergent; Palmolive‚ Morning Fresh and Ultra Coles Brand and the type of bacteria used which are; Micrococcus Luteus and an unknown bacteria from a sponge. Dependent Variable The dependent variable is the factor that is being tested which is the size of the zone of inhibition from the detergent solution and the bacteria. It will be measured in millimetres using a ruler

Report Unknown Bacteria Staining Gram Acid Fast Spore The first practical for microbiology was staining of an unknown bacteria. Professor Goode provided an unlabeled bacteria in which each individual were to conduct gram‚ acid fast‚ and spore staining tests from memory. When the gram staining test was conducted a positive results was obtained. When views on oil bacteria appeared purple and rod-like. I noted this result and looked at the lab key to see what the results narrowed my bacteria choices

techniques‚ is used to identify divide bacteria into two groups: Gram-positive bacteria and gram-negative (Madigan‚ Martinko‚ Dunlap‚ Clark (2009). These staining reactions take advantage of the fact that cells or structures within cells display dissimilar staining reactions that can be distinguished by the use of different dyes (Brown 2009). A gram positive bacteria can be identified by retaining a purple color dye within its peptidoglycan exterior. A gram-negative bacteria‚ which doesn’t retain this purple

Microbiology UNKNOWN LAB REPORT Kateryna Petrakova INTRODUCTION Microorganisms cause a great amount of diseases. For healthcare providers it is very important to be aware of what organisms are pathogenic and cause a disease and‚ therefore‚ to find an appropriate treatment. Different microorganisms require various environments in order to replicate and to become dangerous for a person’s health. An integral part of any medical treatment is to be able to recognize and

Past generations have been able to eat raw beef without even considering consequences like e-coli‚ but at this point in the United States e coli is the least of our worries. It is time to stand up against the food industry and make a change for the better of our world‚ and our future generations. The United States is a country where food is being mass-produced. We
