Determining pH Using a Red Cabbage Farnoosh Mazarei Food Microbiology April 22‚ 2011 Purpose: To test the pH level of many common household object by use of the juice from a red cabbage. Background: pH is the measure of the acidity or basicity of a solution. The pH scale ranges from 1 to 14 with 1 through 6 being acidic and 8 through 14 being basic; 7 is considered neutral. The use of the red cabbage‚ or red cabbage juice is because red cabbage can be used as an acid/base indicator

classification of bacteria according to the Gram stain. Accordingto the chemical make up of bacterial cell wall‚ a staining procedure‚ Gram stain‚ helps usclassify bacteria into two subgroups‚ The cell wall can stain either positive or negative‚depending on its chemistry. If the bacteria stains positive it will retain a purple/blue color. If the bacteria stains negative‚ the bacteria will not retain the purple/blue color‚ but rather have a pinkish/red color.Gram-positive bacteria have a thick layer of peptidoglycan

Whilst foods such as ‘meat’ form relatively well -defined groups of raw materials‚ ‘fish’ constitutes a large range of types (some sources recognise over 20‚000 identified species)‚ caught over

MICROBIOLOGY 3444-007 Gram Negative Unknown Unknown Bacteria #14 LeNaiya Kydd 4/2/2014 Abstract In order to be able to identify the unknown organism that was given to us‚ we had to conduct a number of different tests. These biological tests are used because they help us be able to identify the properties of the unknown we have and be able to compare our observed results with actual results of all the potential organisms. When all of the data of the test are put together it is easy to

INTRODUCTION Total Viable Count is a quantitative idea about the presence of microorganisms such as bacteria‚ yeast and mold in a sample. It counts the number of colonies produced by a very dilute suspension of bacteria on an agar plate and to observe the differential staining behaviour of the living bacteria. This involves counting the colonies produced by viable cells under favourable growth conditions. Some techniques needed before the viable count‚ like pour plate method‚ spread plate method

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 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
