MICROBIAL NUTRITION Nutrition which is also called as nourishment or aliment is a provision to the cells and organisms with the materials necessary to support life. Here it deals with the nutrition in microorganism which is called as microbial nutrition. Nutrients may be divided into three general‚ often overlapping categories: Those that supply energy‚ those that supply carbon‚ and those that supply any and everything else. In this lecture we will consider nutrition from the point

Microbial spoilage There are three types of microorganisms that cause food spoilage -- yeasts‚ moulds and bacteria. Bacteria are round‚ rod or spiral shaped microorganisms. Bacteria may grow under a wide variety of conditions. There are many types of bacteria that cause spoilage. They can be divided into: spore-forming and non-spore-forming. Bacteria generally prefer low acid foods like vegetables and meat. In order to destroy bacteria spores in a relatively short period of time‚ low acid foods must

Control of Population Growth by the Government Population growth is the increase in the number of people who live in a specific area. Population growth has a huge impact of economies‚ education‚ etc.‚ therefore the levels of population growth is a huge concern around the world. There have been a number of countries that have been encouraging the population to produce more offspring‚ such as Shanghai. However‚ these policies are just to motivate the population to have more babies and there are always

Ways to control Population Growth Population growth is the rate of increase in the size of a given area‚ such as a city‚ country or continent. Population growth is closely linked to fertility‚ which is the rate at which women produce offspring. Due to the limited resources on earth and in various countries‚ rampant population growth can lead to inadequate food and other amenities‚ so in certain cases it can be beneficial to attempt to limit population growth. Laws One way for a country or

engineering of microorganisms for their improvement as steroid transforming agents are the areas of drug development. Site selection oxygenation‚ particularly hydroxylation of exogenous steroids is frequent in bacteria genera Bacillus. Several microbial bioconversion of steroids and sterols have been reported‚ focusing mainly on steroid hydroxylations‚ ∆1-dehydrogenation and sterol side-chain cleavage. These biotransformations‚ mostly associated to chemical synthesis steps‚ have provided adequate

Microbial Fuel Cells (MFCs) which capable of harvesting electricity from renewable biomass and organic wastes arise as a promising yet challenging candidate to the existing sustainable energy portfolio (Picioreanu‚ et al. 2010).

Microbial Keratitis Microbial keratitis‚ or corneal infection‚ is a very rare but serious complication of contact lens wear. This website provides information on the infection and its symptoms‚ how to minimise your risk‚ and what to do if you suspect you have an infection. The website provides information resulting from the Australian and New Zealand Microbial Keratitis Study‚ which concluded in 2005. This was a major study looking at the rate and risks of microbial keratitis‚ which collected
