Microscopy

Under the topic microscopy i  learned on the types of microscope..there are optical,electron,scanning probe and scanning acoustic microscope..A few common light microscope such as bright field,dark field,phase contrast and fluorescence..Besides, I learned  on the microscope parts such as the baseocular or the eyepiece and others..The basic techniques of handling and operating the microscope is  compulsory to have for those who are going to use various types of microscope.Once we know how to operate the microscope,then we need to know what type of microbes or any microorganism that we are going to observe and what is the best microscope to be used to observe that particular microorganism.Using a microscope we can classified different type of microbes.For an example bacteria can be classified to gram positive and gram negative bacteria..Now you need to know on what type of stain to be used to determine different type of bacteria..Using the crystal violet stain will give result of dark purple upon gram positive bacteria under the microscope and using safranin willl give result of pink colour upon gram negative bacteria.Other types of stain such as iodine and alcohol..

Introduction to Microbiology

Microbiology is a field of study of  organisms that is too small that cannot be seen with our naked eye.Microorganisms make up a large part of the planet's living material and play a major role in maintaining the Earth's ecosystem. Some contribute advantages and some lead to distruction.Basicaly, microorganisms are divided into six types  bacteria, archea, protozoa, algae, fungi, and viruses.

The study in microbiology can be applied in our life.Microbiologist play an important roles in order to use and to apply the benefits of microbes to the Earth' s ecosystem and mostly to all living thing.

Microbiology can be divided into severals subdisciplines including in food,medical,enviromental microbiology,microbial genetic, and physiology.

Microbes are useful for us in many ways in various industries.. In the production of foods lactic acid bacteria are used to make yogurt, cheese, sour cream, buttermilk and other fermented milk products, vinegars are produced by bacterial acetic acid fermentation and yeast is used in the manufacture of beer and wine and for the leavening of breads. It is also involved in fermentations to convert corn and other vegetable carbohydrates into ethanol to make beer, wine and so for all the bacteria are the agents of most other food fermentations.While in medical and pharmaceutical  microbes can help us in the fight against other microbes. In human and veterinary medicine, that are used to  treat and prevent infectious diseases, microbes are a source of antibiotics and vaccines.
