worked with previously in lab. Initially a Gram stain was conducted in order to distinguish the unknown bacterium as a Gram-positive and/or a Gram-negative organism (Lancaster and Bennett‚ 2012; Kellenberger‚ 2001). Based upon the results‚ both Gram-negative and Gram-positive bacteria were observed in the unknown mixed culture (Table 1 and Table 2; Kellenberger‚ 2001). In order to isolate the two different bacteria‚ colonies that grew on the MSA were used to inoculate Gram-positive tests‚ where as

prepare the Potassium Hydrogen phthalate‚ a 2.00 grams of KHP was measured to an accurate measurement of 1.980 grams. A total of 100 mL of water was mixed with the KHP solution in the volumetric flask to finally prepare an acidic KHP solution. The molar mass of KHP was calculated and came to be 208.252 grams per mole. To find the moles of KHP‚ the mass of KHP (1.980 g) was divided by the molar mass of KHP ( 208.252 g) and .00951 moles are in the 1.980 grams of KHP. To find the molarity‚ the number of

FOR A STAIN REMOVER INTRODUCTION: The Calamansi is a fruit known for its usefulness‚ as well as its amazing use in the field of medicine; however it’s proved to be more than just a food and medicine. It was in fact‚ also a fruit for household purposes‚ and through our various digging of information‚ some researchers found out that calamansi is also beneficial in a lot of things. Such as: Useful for food recipes‚ Eliminates bad smell of fish‚ Skin lightening‚ Take away stains on clothes

1. Obtain 1 gram of an impure‚ unknown substance solid. Make sure to stir the mixture before measuring the sample; record the mixture’s code in the data section. 2. Add approx. 25-50 mL of water and several boiling chips to a 125 mL Erlenmeyer flask and heat the water to a gentle boil using a hotplate. 3. On a second hotplate‚ place a 125 mL Erlenmeyer flask containing the one gram of unknown solid along with a boiling chip. 4. Using a ring clamp‚ slowly pour approx. 5-10 mL of boiling water into

Abstract The primary focus of this lab was on microscopy and simple stains. Crystal violet and Carbol fuchsine‚ simple staining components‚ were used to stain the slide in order to see the different microbes in order to determine their cellular shape and identify unknown ones by comparing. Introduction Bacterial cells are usually colorless because cytoplasm‚ for the most part‚ is transparent. Since the bacteria are colorless‚ it is almost essential to add a stain to make the bacteria more visible

What Beverages Stain Your Teeth The Most? In my experiment I will be testing drinks‚ to find out which drink will stain your teeth the most. The drinks I will be using are coffee‚ soda‚ and tea. I am going to get ahold of an egg and let the egg saok in the diffrent solutions. Coffee is a beverage that is made of roasted or baked beans of several spices‚ that is why people call them coffee beans. Soda is a carbonated soft drink. They have diffrent artifical sweeteners. Just like tea and

Blood Stain Analysis On April 18‚ 2013 at 6:30pm‚ in ballroom 250 at the Student Union Building; I went to one amazing‚ interesting speech on Blood Stain Analysis. Paulette Sutton is from Memphis‚ Tn. She is one of the best forensic investigators‚ which is first called to observe a blood scene. As for her job is to go to a murder scene and investigate how a murder‚ homicide‚ or even a fight occurred according to how the blood splattered‚ or dripped. For someone who just investigated blood and

AIM: THEORY: Page No: C1 Date: To Gram stain the given bacterial suspension and to differentiate between gram positive and gram negative organism. Visualization of microorganisms in the living state is very difficult‚ not just because they are minute‚ but because they are transparent and almost colorless when suspended in an aqueous medium. To study their properties and divide microorganisms into specific groups for diagnostic purposes‚ biological stains and staining procedures‚ in conjunction
