resistance: intrinsic resistance and acquired resistance. There are some methods of observing the capability of the condiments in inhibiting the growth of microorganisms. In the experiment‚ the method used is well diffusion method‚ which used different type of condiments and added into holes of agar‚ where by the inhibition zone by the condiments could be observed. The larger the inhibition zone‚ the more effective the condiment was in inhibiting the growth of microorganisms. 1.2 Objectives By conducting

Introduction Gram staining was developed by Christian Gram in the 1800’s‚ a Danish bacteriologist. (Smith and Hussey‚ 2005) It was the first differential staining technique and most common used in microbiology. Furthermore‚ bacteria are transparent and cannot be seen through the microscope. For that reason‚ Gram staining is an important tool for distinguishing between two main types of bacteria Gram-positive and Gram-negative. The Gram stain differentiates the Gram positive and gram-negative on

Bacterial colonies that have a different shape‚ size‚ or color are generally different bacteria. In this exercise you are streaking only one bacterium‚ so all the colonies should look pretty much the same. You will need the following: 2 tryptic soy agar (TSA) plates Broth culture of Escherichia coli After you have streaked your plates‚ they will be incubated at 37°C. The plates MUST be labeled and incubated in an inverted position. Next
