A micro biological culture Essay

Introduction The tenet of aseptic technique is to prevent the introduction of unwanted little-organisms into your culture or environment. When micro-organism are in the air, they mess enter the culture when the lid is removed. The micro organism ill be culturing is barm which is a fungi. Pure yeast cultures are grown in a medium of sugars, nitrogen sources, minerals, and water. The terminal product whitethorn take the form of dried yeast cells. fungus kingdom are a group of cells or multi cellular cells which feed go from absorption of nutrients.Aim During the course of this project I aim to successfully grow a yeast culture and sterilise the equipment that I use. I also commit to gain the skill of aseptic technique and hope to use it in high level science. Safety There are many safety issues that arise when dealing with chemics and laboratorys that is wherefore when conducting an experiment all safety feels need to be thought some before carrying out the experiment oth erwise someone could occur taint or a serious injury when conducting the experiment.One of the main part of the human frame when carrying out chemical experiments are they plazas do to the fact they can easily be damaged and are all the way one of the most delicate exposed parts of the human body. To cherish these fragile biological sensors a form of nourishion is crucial. The most super C form of eye protection in the laboratory are the gawk. The goggles appear to be precise unattractive to many mass only when and are often interoperated as a burden and not a safety precaution.The goggles are made out of thick shaping which prevents any liquids entering the eye and ca victimisation any disability. Many people who wear converge lenses are under the illusion that there get through lenses will perform as eye protection not realising that the contact lenses are creating a risk of chemicals to become trapped between the lenses and they eye and create extensive eye damage. The goggles can also protect the eye from objects being hurled across the laboratory by immature minds or by the smashing of glass which would send pieces flying in all directions.In the case that somebodys eye/eyes came in to contact with chemicals follow through the procedures of emergency eye was immediately peeing/eye final results should not be directly aimed onto the eyeball, entirely rather, aimed at the beastly of the nose. This increases the chance of effectively rinsing the eyes free of chemicals (harsh streams of water may drive particles further into the eyes). Eyelids may have to be forcibly receptive to attempt eye rinse. Flood eyes and eyelids with water/eye solution for a minimum of 15 minutes.Clothing is also another aspect of laboratory safety it may not seem like it but It plays a vital part in protecting the skin from the harm of chemicals that is why it is advisory to cover as much of the body as possible while dealing with chemicals due to the fact that ch emical can be corrosive and cause damage to the skin. The clothing can armed service by absorbing as much o the chemical as possible leaving hopefully a nonaged amount of the chemical to react with the skin. Another way of avoiding contact of chemicals with skin is to use instruments in laboratory such(prenominal) as pipits to transfer chemicals and tongues to handle test tubes and so forthAnother aspect of safety to consider when dealing with chemicals is diffusion it is a known fact the by inhaling certain chemicals, these chemicals are labelled as toxic chemicals, can cause serious damage with in your body just by inhaling the vapour through the air. One way of preventing this is by blockage lids on all chemicals after use by closing the lid you are also preventing wasteweirs so if the container is dropped the chemical remains at heart the container. Within the laboratory there are frequent goings thats why it is important to try and prevent spillages and knowing what the e ffect of a spillage is and what to do about it.When these spillages occur they can be on modest scale or a disastrous scale. This depends whether the chemical is hazardous or not most lab spillages are on a minor scale and can simply be wiped up by using a damp cloth. With hazardous spillages do not attempt the spillage seek someone qualified to attend to the spillage. A etna burner is very common within a laboratory the importance is safety. As u connects the etna make sure that the hit man pipe is secure and tight. When igniter a Bunsen burner use a splint at ordnance store length and make sure the safety flame is on.This is done by closing the air whole located at the bottom of the Bunsen. elucidate sure that the Bunsen is securely placed on a groove proof mat in the centre of the table the so if the Bunsen tips over it has less of chance of inflicting injury. Before using a Bunsen burner make sure ties are tucked in, long hair is tied back, any lose items of clothing sh ould be tightened or wrapped up and remove all unnecessary item of clothing e. g. jackets. These safety measures should be met to prevent any risk of exculpate.In the event of a acquit take immediate safety precautions such as turning of the gas as soon as possible and call the teacher our a member of staff, if the fire is on any item of clothing you are wearing which cannot be easily removed stop drop and roll. If the fire is out of your control inform the teacher and evacuate the classroom. The inhaling of a micro biological culture could lead to serious internal injury such as infections that is why it crucial not to disperse the culture at once it has grown and seal it tightly so it will not open without extreme force.
