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

Introduction to Biochemistry Biochemistry : a multidisciplinary science that explores the chemistry of living organisms and molecular basis for changes occurring in living cells. Principal areas of Biochemistry 1. Struture and Function of Biomolecules Based on structure depend the function (structure function relationship) Example: Hemoglobin S differs from regular adult hemoglobin (hemoglobin A) by just one single amino acid. A valine replaces a glutamine in the 6th position of the beta

Background Theory Photosynthesis: Plants require water from the soil‚ sunlight and carbon dioxide found in the atmosphere for growth and development. In the process of photosynthesis‚ carbon dioxide and water – in the presence of chlorophyll and light energy – are converted into sugar and oxygen‚ which is given off as a by-product. Generally‚ as sunlight increases in intensity‚ the rate of photosynthesis also increases [1]. This means greater food production within the plant. Many garden vegetables

Lichens are composite symbiotic organisms consisting of a fungus and a photosynthetic organism (usually algae or a cyanobacteria). Current approaches to therapy : • Image showing the spongiform changes found in brains of prion disease-affected individuals.

other words is the process of conversion of atmospheric nitrogen in to a form that growing plants can use. A little number of conversion occur in lightning strikes‚ all the rest is done by bacteria. Nitrogen fixation is done by many types of cyanobacteria‚ which are photosynthetic‚ and various types of non-photosynthetic bacteria‚ for example Azotobacter‚ and actinobacteria. In order to fix nitrogen these bacteria consume large amounts of ATP and an enzyme called nitrogenase. To be more detailed:

Water pollution in China is a serious problem. It threatens the health and well being of humans‚ plants‚ and animals and it is one of most common types of pollution. This paper will outline the negative affects of water pollution in Lake Tai that is caused by industries in China and the effects that it has on surrounding communities. The Chinese government is aware of the pollution problem in its country; however China has pursued economic growth any cost‚ growth is too fast for the government to

The truth‚ that in the bid to improve our lives‚ we have put our own survival to stake‚ is finally hitting us hard. When is it that we are going to learn... when is it that we will understand that the well-being of the environment and our survival are intricately woven into each other. Good morning respected teachers and my dear friends ...today I Nikita am going to speak about how human activities are affecting flora and fauna? We are facing a serious crisis in biodiversity‚ the variety of animals
