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

What Is Microbiology? Microbiology is the study (logy) of very small (micro) living (bio) things. Microbiology is the study of microorganisms. These "bugs" include: bacteria (that’s the Latin plural for bacterium); viruses (that’s the non-Latin plural for virus - virii sounds weird‚ so I don’t say it); and‚ fungi (that’s the Latin plural for fungus - which by now you have guessed‚ or already knew‚ and may not be all that interested to know‚ anyway). Microbiology is actually made up of several

experiment‚ Escherichia coli is used as a sample to study the growth kinetic of microorganism in shake flask. A different volume of E.coli was transferred into 250ml Erlenmeyer/shake flask containing media for the nutrient of microorganism. The different volume of microorganism transferred will give the different effect of reading on the constant volume of media used. There are three ways to test the growth kinetic rate of microorganism on shake flask‚ which are by optical density (OD)‚ glucose analysis and

How would you convince a friend that microorganisms are more than just disease causing agents? An entire kingdom of microorganisms was brought into life 3 billion years ago. Since then «the earth is a fundamentally a microbial planet‚ to which the micro-organisms are recent the relatively unimportant additions» (Wheelis‚ Mark‚ Principles of modern microbiology‚ 2008‚ p.1). The term microorganisms consist of bacteria‚ archaea‚ fungi‚ and protest‚ which can either be unicellular or multicellular
