Discussion: Each test is a pertinent contribution to drawing an educated conclusion. After performing the gram staining and observing which unknown culture was gram positive, a catalase test was performed. The catalase test allows lab workers to differentiate Staphylococci and Streptococci genus. The test was performed only on the gram-positive culture. Bacteria that respire by the use of oxygen, otherwise known as aerobic respiration, produce enzyme or “catalase”. This protects the bacteria…
will later on lead you down a certain side to contribute in defining the genus and species. All the following procedures were carried out on the gram positive cocci unknown in this order: Catalase, Oxidase, Nitrate Reduction, Oxidation-Fermentation, Phenol Red, Bacitracin, Coagulase, and lastly, Gelatin Hydrolysis. These tests led me to believe that unknown number 93 is Kocuria rosea. Discussion Looking at the dichotomous key, the first test that helps narrow down the bacteria…
Bergey’s manual was used to identify the unknown to be either from genus Flavimonas also known as Pseudomonas or Frateuria based on the results of the experiments. Multiple different experiments were conducted to identify the unknown, however only seven characteristics of the unknown were discovered from the data in Bergey’s manual. Not all test performed in lab were used due to the fact that some tests were not listed on the manual, while others did not apply to the category of the bacteria.…
Now days, microorganisms are very important to identify to Genus and species because they can cause various diseases. We need to know that what helpful or harmful microbe in this environment. This project’s purpose is to identify an unknown bacterium by various methods. Most stains used in microbiology are differential stain, which use more than one dye so that different cells, chemicals, or structures such as Gram staining, TTC reduction, Oxygen requirement test, Catalase test, Nitrate test,…
when combined with rose and juniper oil. Bay contains a rich mixture of active ingredients, including alcohols, esters and terpenes. Phenols: Phenols give bay oil its warming properties. They are stimulants to the nervous system, activate healing and are highly antiseptic. Oils such as bay may irritate your skin if used in high concentrations. The principal phenol in bay is eugenol. Also found in clove and cinnamon, eugenol gives bay a spicy, clove-like fragrance. Cineole oxide: Also known…
Sausage is one of the most important and popular meat products throughout the world. Production of dry cured sausage is an important part of the meat industry. Its production process comprises blending the meat with curing ingredients, flavoring and coloring agents in order to accomplish an acceptable product with respect to sensory and technological properties. Nitrite / nitrate is a key ingredient which is employed in meat products for curing. Nitrite plays the following roles: 1- It…
as olive, coconut, sunflower and rice bran oils, the emulsification activity of biosurfactants. Pseudomonas aeruginosa had higher emulsification activity than Saccharomyces cerevisiae. While checking the sugar and lipid content in biosurfactants by phenol sulphuric acid method and vanillin reagent method, found high in Pseudomonas aeruginosa than Saccharomyces cerevisiae. Under this study, after centrigugation of crude extract,the pellets were suspended in a 40 mL of dichloromethane in a…
beneficial changes in better sensitivity to improvements in blood clotting; these changes aid in the prevention of small blood clots that block arteries being the major cause of heart attacks and strokes. In addition, beer and wine contain antioxidants (phenols) that protect against heart disease. The high alcohol content in vodka kills bad odor in the mouth. Also, consuming alcohol in moderation helps the neurons in the brain by aiding in the recovery of the use of each neuron as it is known…
species of oregano especially in the Mediterranean. There are a multitude of conditions that Oil of Oregano treats, but the most famous use is its ability to kill infections in the body. Most organisms cannot survive when exposed to the powerful phenols (carvacrol and thymol) which are the active ingredient in this Wild Oil of Oregano. These ingredients work well on their own but have an added potency when found together in nature. The ancient Greeks were among the first to take advantage of…
