24, 2014 Unknown number: thirty-four I. Abstract There are many types of bacteria and they produce different enzymes. However, some bacteria can produce same enzymes. In order to identify the particular enzymes produce by each bacteria specific test needs to be done. Among various types of enzyme producing bacteria, gram- negative and gram-positive bacteria are given priority in our experiment. There are four main types of Gram-negative bacteria and four Gram-positive bacteria including: Escherichia
right treatment is prescribed to a patient; in controlling and preventing disease outbreaks, and in laboratory studies. In this experiment, a series of tests were conducted to narrow down and identify the unknown bacteria. In the first step of identification, a sample of bacterial culture was used from the tube labeled #17 to perform a Gram stain test. As controls, Staphylococcus aureus, gram-positive cocci that stain purple, and Escherichia coli, gram-negative bacilli that stain pink, were stained
was differentiated and identified through a series of biochemical tests. After performing the tests on the
Title: Analysis of Mini unknown Summary: A series of test was done with Microbe 3B. A Gram stain was done and the sample was gram positive. A streak plate was completed revealing that the microbe was circular, convex, entire, smooth, yellow, and opaque. The last test completed was the MSA. The microbe was oxidase positive. Thus, Microbe 3B was Micrococcus luteus (Sarcina). (MMB,2015) Procedure 1 Gram stain: Purpose/ Introduction: The Gram stain reveals whether a microbe is gram positive
