* -Coagulation 65. Describe the physical change that occurs during lactose fermentation. Name one microbe capable of producing this reaction. * Lactose Fermentation involves the initial breakdown of lactose to glucose and the subsequent fermentation of glucose to produce an acid end product. 66. Describe the physical change that occurs during an alkaline reaction. Name one microbe that would produce this response. * This change to the media will impart a blue color throughout

In 1676 Leeuwenhoek saw tiny organisms in water‚ he was the first man to observe and describe bacteria accurately. He discovered microscopic nematodes‚ blood cells and sperm. He also made over 500 microscopes to view specific objects. B. Microbiology is concerned with the study of all forms of life that are too small to be seen with the naked eye. Antonie’s work

BRONCHOPNEUMONIA Bronchopneumonia or bronchial pneumonia or Bronchogenic pneumonia is a type of pneumonia that is characterized by an inflammation of the lung generally associated with‚ and following a bout with bronchitis. This inflammation starts in the small bronchial tubes the bronchioles‚ and irregularly spreads to the peribronchiolar alveoli and alveolar ducts with a diameter of about 3 to 4 inches. The result is that the inflammatory changes lead to the localized

gets digested not by enzymes or acid as in the human stomach‚ but by the millions of microbes that live there and break down food through a process called rumen fermentation. Unlike the human stomach‚ which is relatively immobile‚ the rumen contracts about two times each minute‚ mixing its contents and ensuring that all food encounters the digestive microbes. Rumen fermentation is the process by which the microbes living in the cow ’s rumen break down the cellulose‚ or fibre‚

A FERMENTER OR BIOREACTOR MICROBE INPUT :- The microorganisms that will carry out the fermentation process are cultured separately until they are growing well. These are introduced into the fermenter through the microbe input. NUTRIENT INPUT :- The microorganisms require an energy source to carry out fermentation. The energy source is usually a carbohydrate. Growth materials like amino acids for protein synthesis are also added through the nutrient input. STERILE CONDITIONS:- It is necessary

injected materials from a cowpox virus into an 8 years old boy. By doing so he guessed that this would provide the protection needed to save many people from deadly outbreaks of the smallpox virus and it turns out to be successful. When foreign microbes invade the human bodies‚ the immune system is automatically activated itself to a series of responses by 1) identifying the invaders from entering the body and 2) eliminating them before it can harm the hosts’ bodies. The immune system is a way to

CHAPTER I INTRODUCTION 1.1 Background Food is one of human sources of calorie‚ protein‚ fats‚ and nutrition. Yet‚ because of the highly nutritious content‚ food is susceptible to growth of microorganisms. By the presence of microorganisms in food‚ the food is more likely to have shorter shelf life. Thus‚ mostly it is resolved by the addition of antimicrobial substances to food‚ such as condiments and preservatives. Condiments and preservatives could inhibit the growth of microorganisms

Microbial metabolism is the means by which a microbe obtains the energy and nutrients (e.g. carbon) it needs to live and reproduce. Microbes use many different types of metabolic strategies and species can often be differentiated from each other based on metabolic characteristics. The specific metabolic properties of a microbe are the major factors in determining that microbe’s ecological niche‚ and often allow for that microbe to be useful in industrial processes or responsible for biogeochemical
