NTRODUCTION Often in the study of microbiology‚ the need to identify an unknown microbe may arise. This aids in the recognition of which microbes are harmful or pathogenic as well as those that may be beneficial to us in some way. This report will detail how a similar project was performed in order to identify two unknown micobes using the techniques that were learnt during the course of the semester. We embarked on the project with the knowledge that we would have to identify a Gram(+) as well

Regarding the cell walls of bacteria‚ a Gram stain determines what kind of bacterium the cell is. The Gram stain works by creating a purple dye that either attaches or fails to attach to the peptidoglycan either found or not found on the cell wall of the cell. Gram-positive bacteria are cells that have a large amount of peptidoglycan in their cell wall‚ and those that are Gram-negative have an extra cell

It is a story of epidemics such as the black plague and typhus‚ which ravaged Europe in the Middle Ages‚ killing millions in every city‚ and of smallpox‚ which swept through the New World. The battle is not over‚ however‚ and never will be. Pathogenic bacteria‚ fungi‚ viruses‚ protozans‚ and worms continue to plague every society and indeed every person. They are

In 1883 Hans Christian Gram discovered an important staining method that is used extensively today. The stain is called the Gram Stain. This experiment was done in order to differentiate microbes into two basic groups: Gram positive microbes and Gram negative microbes. The purpose of this

❖ INTRODUCTION • DEFINITION Minimal processing is defined to include all unit operations such as washing‚ sorting‚ trimming‚ puling‚ slicing‚ coring etc. The purpose of minimal processing is to deliver to the consumer a like fresh with an extended self life whilst ensuring food safety and maintaining sound nutritional and sensory quality i.e. at least 7 days domestic consumption and 7-15 days for overseas consumption. Minimally processed products are also called fresh cuts

the high moisture contents favors the faster-growing yeasts and bacteria. The deficiency of vitamin B discourages some bacteria. The normal change to be expected in raw yogurt in room temperatures is an alcoholic fermentation by yeasts‚ followed by the oxidation of the alcohol and yogurt acids by film yeast or molds growing on the surface if it is exposed to air or the oxidation of the alcohol to acetic acid if acetic acid bacteria are present. In additional to the usual alcoholic fermentation
