Introduction

Comparison of the Laboratory and Industrial Processes GNVQ Intermediate Science When going through the process of fermentation in a laboratory they use certain methods to achieve their goals and some of the methods that they use are completely different from the ones that are used in the industry of fermentation. A fermenter is a container that maintains optimum conditions needed to grow a particular organism I will be using different criteria's to compare the laboratory and industrial process of fermentation in this assignment; some of them are listed below: * Equipment Used * The Quantity of the Product * Method Used * Quality of the Product Before I get right on into the assignment I will firstly talk about penicillin is and what it is used for today in our society because penicillin will come up. Penicillin was discovered by Alexander Fleming in 1929 and penicillin is one of the earliest discovered and widely used antibiotic agents, derived from the penecillium mold and the use of penecillium did not begin until the 1940s. Penicillin kills bacteria by interfering with the ability to synthesis the cell wall and this will disallow it from splitting and reproducing and it will only lengthen longer Below are is a table that shows the most obvious differences in fermentation in a laboratory and fermentation in the scientific industry: Laboratory Fermentation: Industry Fermentation: It is ...read more.

A thermometer is not used in a laboratory because they would rather use cheaper equipment probably and choose not to use a thermometer. * Batch/Culture Industry: - In the industry they use something called contous Culture and what this means is to grow the culture and Then they will be able to repeatedly use the same Culture over and over again, so it's basically like Recycling the yeast culture and in a laboratory they use Something called batch culture which means that they Yeast culture is grown, used once and then killed. * Food Supply: - When scientist do fermentation in the laboratory they would often Feed the yeast culture only once and that would be in the beginning of the experiment, and from this point on the yeast population will not be fed again, but on the other hand in the scientific industry they would do something called food replenishment, which basically means to continually feed the yeast population probably daily or weekly, this way they yeast wont ever run out of food and the yeast culture is being used again and again so its just one cycle. Above are only the equipment that the science industry use when they use fermentation, I will now write about the added features that the industry fermenter has equipped onto itself and why they use it. ...read more.

Conclusion

yeast cells, this is so that it helps them reach their specifications, because the industry would like to try and obtain 100% success, perfect fermentation! They cannot allow anything to go wrong at all when they are performing the fermentation, this is because the solution is quite delicate and it can become infected and then they will have the start the process straight from the beginning again, this is why in the industry they use pure culture, it lessens the chance of it becoming infected and also it helps them to achieve something close enough to 100%, their specification! Also, in the scientific industry they do something called 'quality control' this is basically what it says it is, it is to control the quality of the product by taking samples of the product along the processing of it, for example the diagram below fully explains what quality control is and how it works. 1. Three or so samples of the product are taken and then checked if it is within tolerance and if so they continue with the production of the product. 2. If the product is not within tolerance then they will make adjustments to the product and try and make it as good as possible than before, they will then run the production again and check if it is within tolerance. 3. And the whole cycle starts again! ...read more.
