accidentally by Sir Alexander Fleming in 1928 at St. Mary’s hospital in London when he forgot to clean a Petri dish before leaving on vacation. Fleming’s experimentation with the left-behind mold led him to discover its dissolving effects on the Staphylococcus aureus bacterium. Through further trials he discovered that a pure culture of the mold effectively killed the harmful bacteria. 3) The Human Genome Project The crusade to map all human genes began in 1990 and was completed in 2003.

most common cause is Staphylococcus aureus. Mastitis is usually followed by swelling and redness of the cow’s udder. Testing for this you would use a strip cup test to see if the bacterium is present. You then take the result for this and see how bad the bacterium is‚ so then you would be able to carry out more investigations and be able to find out control methods. These methods would be hygiene and regularly cleaning the milking machines. 2.0 Introduction Staphylococcus aureus is one of the

MILK FABRIC ABSTRACT: The milk fabric is new born fabric. The milk protein fabric moistens skin and it is healthy and bacteriostatic - it is the perfect material to produce underwear and socks‚ pants‚ long-sleeve T’s and jackets also. The important ingredients of milk protein fiber are milk casein proteins‚ which can nourish and lubricate the skin. The milk protein contains the natural humectant factor‚ which can capture the moisture and maintain skin’s moisture to make the skin tender and smooth

Experiment 9: Growth curve of Serratia marcescens Abstract Bacteria grows by binary fission. The aim of this experiment is to follow the growth of Serratia marcescens in nutrient broth at 37oCby recording the changes in turbidity (cloudiness) by measuring the absorbance of visible light (600 nm) and also to prove that there is an increase in the cell number and not just in mass during the growth. In the experiment we measure the full growth curve of Serratia marcescens by measuring the absorbance
