IDENTIFYING GRAM POSITIVE COCCI As mentioned in Exercise 8‚ “Identifying Gram Negative Rods”‚ identifying bacteria is a common activity in the microbiology lab. Like the game Clue™‚ each time you gather a piece of information to solve the mystery‚ you gather some information that supports some identities and eliminates others from contention. In the lab‚ the process continues as you gather more information until only one microbe remains and all others have been eliminated as possibilities. Thus

Sampling of Gram-Positive Bacteria and Antibiotic Resistance Resting We thought it would be interesting to find out the different bacteria that grow on things we use on a daily basis and the level of antibiotic resistance that those bacteria have. We chose to swab the toilet seat in the MATC women’s bathroom and the ATM machine in the commons area on campus.

Gram Stain: Gram is an empirical method to distinguish the species of bacteria into two groups Gram-positive and Gram-negative based on the physicochemical properties of the cells. First‚ a smear was prepared by use a sterile transfer loop that been flamed to removes some bacteria from slant agar and placed on the slide; mixed with one drop of water and let air dried. After dried‚ heat fixation the slide by passed the slide over a flame quickly 2-3 times to stick bacteria to the slide. Next‚ the

INTRODUCTION The Gram Negative lab had two parts; the aim of the first part is to determine the concentration of gram negative bacteria in a water sample collected from a creek near Providence Road‚ Strickling. Gram negative bacteria have a cytoplasmic membrane‚ a thin peptidoglycan layer‚ and an additional outer membrane composed of phospholipids and lipopolysaccharides. Because gram negative bacteria have a relatively thin cell wall when compared to gram positive organisms‚ they are consequently

OYSTER SHELL AS CLOTH STAIN REMOVER Hypothesis 1. Oyster shell will be an effective alternative stain remover if further developed. 2. Pounded oyster shell has calcium carbonate. Calcium carbonate or chalk is one of the components of the detergent. .3. This will be ideal for promoting the care for our environment since it doesn’t have any harmful effects to plants and other organisms. 4. Soaking the stained cloth in distilled water with pounded oyster shell
