Abstract The primary focus of this lab was on microscopy and simple stains. Crystal violet and Carbol fuchsine‚ simple staining components‚ were used to stain the slide in order to see the different microbes in order to determine their cellular shape and identify unknown ones by comparing. Introduction Bacterial cells are usually colorless because cytoplasm‚ for the most part‚ is transparent. Since the bacteria are colorless‚ it is almost essential to add a stain to make the bacteria more visible

What is Food Microbiology Food microbiology is the study of food micro-organisms; how we can identify and culture them‚ how they live‚ how some infect and cause disease and how we can make use of their activities. Microbes are single-cell organisms so tiny that millions can fit into the eye of a needle. They are the oldest form of life on earth. Microbe fossils date back more than 3.5 billion years to a time when the Earth was covered with oceans that regularly reached the boiling point‚ hundreds

unknown bacteria from a mixed culture provided to us. This study was done by applying all of the methods that have been instructed on thus far in microbiology laboratory class. Each test performed‚ provided us with some key information about the unknown microbes in question . The identification of unknown bacteria is a time honored part of microbiology courses. It will challenge knowledge and skill in performing laboratory techniques‚ ability to critically evaluate the information obtained from

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
