Identification of Unknown # 15 Abstract. One of the most fundamental differential staining techniques used in the study of bacteriology is gram staining. There are two main types of bacteria‚ gram negative and gram-positive. The purpose of this experiment was to perform a variety of tests to identify the bacteria contained in the unknown sample labeled number 15. The following are the tests that were used to identify the two different bacteria. The

The first test conducted on unknown bacteria 32 was the Gram stain. From this stain‚ unknown 32 was found to be a Gram-positive cocci. This test eliminated all possible Gram-negative bacteria‚ Gram-positive rods and Gram-positive spirillium. Next‚ the endospore test determined whether or not the Gram-positive bacteria contained endospores. With the use of malachite green‚ steam‚ and safranin it was found that unknown bacteria 32 did not contain endospores. This eliminated Gram-positive cocci Sporosarcina

Research Question: How does increasing the concentrations of Dettol Antiseptic Liquid from 0% to 100% affect the growth of Escherichia coli bacteria on the agar plates? Hypothesis: As the concentration of Dettol Antiseptic Liquid increases the inhibition of bacterial growth around the antiseptic disks also increases. Variables: |Type of variable

pyogenes. The sputum sample was first inoculated in the agar plates MAC‚ SBAP‚ CHOC and also a direct gram stain of the sample was performed. After a day of incubation‚ the MAC agar gave a negative result‚ therefore it is not a Gram-negative bacteria and non-lactose fermenting. The SBAP and CHOC showed growth of colonies. The CHOC agar had a mixed formation of colonies (gray colonies and 2+ tan colonies)‚ so it was isolated in another CHOC agar and it was mixed again. A gram stain procedure was done
