The Gram stain is one of the most useful staining procedures in microbiology . It is one of three differential staining techniques‚ is used to identify divide bacteria into two groups: Gram-positive bacteria and gram-negative (Madigan‚ Martinko‚ Dunlap‚ Clark (2009). These staining reactions take advantage of the fact that cells or structures within cells display dissimilar staining reactions that can be distinguished by the use of different dyes (Brown 2009). A gram positive bacteria can be identified

The problems that arise regarding the antibiotic resistance of certain bacteria has continue to worry the health industries. One of these bacteria is the Staphylococcus aureus. It has been one of the major causes of hospital-acquired infections which has resulted to a lot of deaths each year. Description Staphylococcus aureus is a gram-positive bacteria which indicates that it has a cell wall structure with a thick layer of peptidoglycan. It is a facultative anaerobe which allows it to perform

One of the most basic Filipino dipping sauces is made with soy sauce and calamansi juice‚ called toyomansi; and a simple‚ yet flavorful marinade is a blend of soy sauce‚ calamansi juice‚ vinegar‚ pepper‚ and garlic. While many growers see the calamansi as tiny decorative oranges and mostly ornamental‚ they are finding that the trees are problem free and easy to cultivate

Introduction- This lab experiment serves as a model for community succession using bacterial colonies as the model. A bacterial colony grows from a single bacterium and is composed of millions of cells. Each colony has distinctive colony morphology: size‚ shape‚ color‚ consistency‚ and color. Community succession is a phenomenon observed in the organizational hierarchy of all living organisms. Community succession is not limited to bacterial colonies‚ but spans the entire community of life

of the Pineapple peeling as stain remover. We observe that people who can’t afford commercialized stain remover use vinegar as alternative. And mostly of the vinegar are made up in coconut‚ apple and etc. We want to find out if pineapple peeling extract is effective as stain remover. That’s why we come up with this project/ experiment. Statement of the Problem and Objectives 1. To prove the effectiveness of the Pineapple Peeling as a stain remover 2. To know how long

Introduction Although bacteria is microscopic in size‚ it is largely important in the healthcare field‚ environmental work‚ food preparation‚ as well as many other industries. In particular‚ it is essential that healthcare workers be able to identify the species of bacteria invading a human reservoir in order to prescribe the correct antibiotic that will kill that species. For the purpose of bacteria identification‚ numerous tests have been devised to find out the exact species in question. However

4: Cell Structures and the Gram Stain Purpose: The purpose of this lab is to familiarize the student with the use of a compound microscope and the Gram Stain test. Students will review a brief video and slides to introduce the compound microscope. Students will also view a video about the Gram Stain procedure and then answer questions related to it. Hypothesis If I look at the slides I will see where the cell wall is and what lies inside it and in the Gram Stain if I watch the video I will learn

Escherichia coli and Staphylococcus albus Some bacteria’s require a certain amount of light in order to function properly and there fore survive. Escherichia coli is found in the gut and intestines of mammals. Staphylococcus albus is generally a skin dwelling bacteria Aim: To test whether the amount and type of light that the bacteria’s E.coli and S.albus are subject to causes changes in their growth rates and habits. To test whether the growth rates and habits of the bacteria’s E. coli
