Sterilization (or sterilisation, see spelling differences) refers to any process that effectively kills or eliminates transmissible agents (such as fungi, bacteria, viruses, spore forms, etc.) from a surface, equipment, article of food or medication, or biological culture medium. Sterilization does not, however, remove prions. Sterilization can be achieved through application of heat, chemicals, irradiation, high pressure or filtration. ApplicationsFoodsThe first application of sterilization by Nicolas Appert was thorough cooking to affect the partial heat sterilization of foods and water. Cultures that practice heat sterilization of food and water have longer life expectancy and lower rates of disability. Canning of foods by heat sterilization was an extension of the same principle. Ingestion of contaminated food and water remains a leading cause of illness and death in the developing world, particularly for children. From Wikipedia under the

It is for a microbiology and chemistry class Asked by LULU8908 - Thu Sep 10 12:56:43 2009 - - 2 Answers - 0 Comments A. Because the Bacillus anthracis spores are ridiculously resilient and can survive a long time (like decades and centuries): "Bacillus anthracis spores in particular are highly resilient, surviving extremes of temperature, low-nutrient environments, and harsh chemical treatment over decades or centuries." Answered by Firedragon524 - Thu Sep 10 13:08:55 2009 this is a long shot but can anyone help me find some definitions?
Q. out of the 84 definitions i had to do for my microbiology class over this break, these are the two i can not figure out, ive looked online and in every book i have. i can get a partial definition but not close enough. my teacher is picky about specifics. Ethylene oxide gas sterilization- alcohol- 95% and 70%- yes, i know what alcohol is, but i need the specific definition for both percentages. i need to define the following... Ethylene oxide gas sterilization 95% alcohol 70% alcohol Asked by marlasinger5 - Sun Dec 30 19:44:39 2007 - - 2 Answers - 0 Comments A. Ethylene Oxide (EO) gas is a satisfactory method of sterilizing plastic, rubber and many other items, which will not withstand steam sterilization. Source is the second eo gas link. (First link jic.) Alcohol (95%) is a mixture of ethyl alcohol and water. It contains not less than 92.0% w/w and not more than 92.7 w/w ethyl alcohol, corresponding to not less than 94.7% v/v and not more than 95.2% v/v at 15.56 C. I searched for the Alcohol 70% but could only find references to Rubbing Alcohol or "Isopropyl Rubbing Alcohol 70%". Sorry I couldnt be more help there.
