Bacteria Growth and Glucose Percentages

Bacterias dispatchshoot Affected by Various Glucose Percentages This research laboratory tested whether or not antithetic glucose levels activated bacterium harvest-time. My lab assembly and I wanted to figure out, if more(prenominal)(prenominal) glucose was dissemination on the bacterium surfaces, would thither be more bacterium fruit in the agar plate. My throng predicted that with 25% glucose (the highest percentage of glucose), the bacterium growth would be the greatest. In order to conduct this experiment, my group had 3 ager plates. One plate had 0% glucose, the next plate had 5% glucose and the one-third plate had 25% glucose in it.Once we acquire all the plates, we light an alcohol burner. We because used a pipet to sterile collect bacteria from the culture tubes. We accordingly capable the first ager plate (0% glucose) and transferred 10 drops of bacteria culture onto the plate. Then we did the identical for the next 2 plates (5% and 25% glucose). Next, we sterilised the broadcaster by waving it in the flame (alcohol burner) for 15 seconds. Then, we let the spreader cool for 10 seconds, and then opened the first agar plate and spread the bacteria around the plate by quickly and slightly sliding the spreader back and forth across the plate for 5 seconds.Then we closed the plate and did the same(p) thing for the next 2 plates. Next, we pissed each plate with a ecdysiast of Para film and then situated the plates with bacteria on the side of the way of life until the following week. After waiting a week, we received our groups ager plates back. We observe that with our experiment, the most mensuration of bacteria growth had no glucose in it. Our results were the following with no glucose, there was 25% bacteria growth, with 5% glucose added to the ager plates, there was only 15% bacteria growth, and with 25% glucose added to the ager plates, only 1% of bacteria growth was present.The least amount of bacteria growth contained the largest percentage of glucose. Based off of our groups results, we can pass up our hypothesis. We realized that our expectancy was not what our results showed us. Our prediction was that 25% glucose would have the most amount of bacteria growth, however we can directly conclude that bacteria growth does not need any glucose to reproduce. In fact, the more glucose there is, the least amount of bacteria growth occurs. If glucose is present in the bacteria, it is achievable for bacteria to reproduce however bacteria will reproduce the greatest when no glucose is present at all.
