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

Hydrogen Fuel Cell Cars: Worth the Investment? Hydrogen is the most abundant element in the universe‚ but only recently have people been able to harness this resource and turn it into energy. Hydrogen fuel cell cars are one such advancement made in the effort to turn hydrogen gas into electricity. Fuel cells in the car are used to convert hydrogen into an electrical current‚ and thus power the vehicle. Fuel cells convert hydrogen and oxygen into water while producing electricity.
