Aseptic Technique.

Extracts from this document...


Introduction: Aseptic means without microorganisms. Aseptic technique refers to practices that help reduce the risk of post procedure infections in clients by decreasing the likelihood that microorganisms will enter the body during clinical procedures. Some of these practices are also designed to reduce service providers' risk of exposure to potentially infectious blood and tissue during clinical procedures. Only the wanted bacterium is invited to the experiment. Aseptic techniques are those that do some or all of the following: Remove or kill microorganisms from hands and objects. Empty sterile instruments and other items. Reduce client's risk of exposure to microorganisms that cannot be removed. Not to forget, the aim of the experiment is to make a culture of bacillus subtillus using aseptic technique. ...read more.


7) Just then I put the lid back on the petri dish immediately. 8) Finally I flamed the loop and allowed it to cool naturally. Safety Points Using aseptic technique if safe can prevent contamination such as bacteria, yeast, fungi and spores. Not to mention the environment such as people walking by, windows open and some lab equipment can introduce contaminated air. Extending the safety of the human being, washing hands and tying hair back would be necessary and taking when sick would make the experiment inaccurate. Cleaning all equipment that could be contaminated should be cleaned due to the fact that they can be infected with any sort of chemical bacteria. Results: Dish 1 Dish 2 Evaluation: After streaking the agar jelly and totally finishing my experiment, I was happy with the outcome of my result. ...read more.


Industrial aspects: Every Scientist that uses micro organisms has to use aseptic technique for their own safety. This will ensure that their culture of micro organism will be pure and therefore it will be free from other micro organism and also ensures that it does not go in to the air which will make people ill. Mentioning brewers, they use the yeast left over at the end of brewing to start their next brew. However, because of changes occurring to the yeast, they have to replace it with a pure yeast culture, about every ten brews. They will keep a pure culture of yeast in the refrigerator on an agar slope - you will culture it on a malt agar plate. Scientist's main indulgent of aseptic technique is to investigate bacterial samples when while researching bacterial diseases. Irslan Salim 11H ...read more.

    Have a control Petri dish were there is no water. This is to show that there should be no bacteria in the Petri dish were it empty. 6. The agar has previously been sterilised and kept as a liquid in a water bath at 60�C.

  2. Respiration of yeast

    The yeast that we used in our practical is technically classified as saccharomyces cerevisiae, as this is used for baking, brewing etc. We used this yeast as it most commonly studied in cell biology. It is also the microorganism behind the most common types of fermentation.

  1. The comparison of bacterial content in a range of milks.

    Exposure to exterior bacteria-results in contamination and inaccuracies. To prevent this the samples must be kept well away from possible sources of contamination-e.g food products or yeasts (that could increase the bacterial growth) etc. Also, it would be a good idea to wash your hands before each experiment, to eliminate contamination when handling the equipment.
