The Effect of Convallaria Root Concentration on the Rate of Fermentation
Total CO2 Evolved by Different Concentrations of Convollaria roots. Actual values are the graduated pipette readings. For CO2 evolved values, subtract the initial reading from the actual reading. This is the amount of CO2 accumulated over time. | Time (min) | Tube 1 | Tube 2 | Tube 3 | Tube 4 | | Actual | CO2 Evolved | Actual | CO2 Evolved | Actual | CO2 Evolved | Actual | CO2 Evolved | | (A) | (A-I) | (A) | (A-I) | (A) | (A-I) | (A) | (A-I) | Initial reading (I) | 0.05 | | 0.01 | | 0.02 | | 0.05 | | 2 | 0.16 | -0.84 | 0.12 | -0.88 | 0.19 | -0.81 | 0.23 | -0.77 | 4 | 0.24 | -0.76 | 0.5 | -0.5 | 0.37 | -0.63 | 0.36 | -0.64 | 6 | 0.3 | -0.7 | 0.54 | -0.45 | 0.49 | -0.51 | 0.5 | -0.5 | 8 | 0.45 | 0.55 | | | 0.61 | -0.39 | 0.62 | -0.38 | 10 | n/a | n/a | | | 0.73 | -0.27 | 0.75 | | 12 | | | | | | | | | 14 | | | | | | | | | | | | | | | | | |

Discussion

In this experiment, the amount of CO2 evolved for different concentrations of Convollaria roots was studied. The question being answered was what kind of effect the increase in concentration of Convollaria roots had on the rate of fermentation. The hypothesis was that the antimicrobial activities in Convallaria majalis’s roots would hinder the process of yeast fermentation because it will cause self- destruction or death in the microorganism of the yeast. If the antimicrobial activities in Convallaria majalis’s inhibit yeast fermentation, then the amount of CO2 evolved in the fermentation process will slowly decease or no CO2 will be formed. However, the results did not confirm our prediction because the Convallaria produced an increasing amount of CO2. Thus, the plants extract increased the rate of yeast fermentation.
There may be several reasons why the Convallaria roots yielded a fast rate of fermentation, instead of inhibiting the amount of CO2 evolved. One reason is that the Convallaria Majalis roots contain

    Purpose: The purpose of this lab was to gain a complete understanding around the rate of cellular respiration within multicellular organisms, also to research and understand how to use a CO2. Background: Living systems require free energy and matter to maintain order, to reproduce, and grow. Energy deficiencies cause disruptions at the population and ecosystem levels as well. 1 mol of H2O produces 1 mol of CO2 through cellular respiration. Autotrophic organisms capture free energy from the environment through the process of photosynthesis and chemosynthesis.…

    Photosynthesis in Opuntia does not work the same way as in C3 plants because Opuntia is a CAM plant. Opuntia lives in a deserted region where it is hot and dry. Thus, Opuntia wants to conserve as much water as it can. To achieve this, the C4 pathway and the Calvin cycle take place at two temporal parts. In the mesophyll cell, at the C4 pathway carbon dioxide is hydrated to form bicarbonate ion, which reacts with enzyme, phosphoenolpyruvate, to produce the four-carbon compound, oxaloacetate. This process occurs at night when the stomata of the cactus are open and CO2 (Carla) was diffused in. Oxaloacetate is then reduced to malate, which is stored as malic acid in the vacuole. However, during the daytime malic acid is turned back into malate and is broken down to pyruvate and CO2. Exhausted, Carla complains on the purpose for traveling to different locations. Poor Carla, she doesn’t know that she is not even half way through her journey…

    The two types of fermentation that are well known are alcoholic fermentation as well as lactic acid fermentation. Fermentation is vital for many organisms, such as yeast and bacteria, because it allows them to obtain energy required to carry on life processes. Alcoholic fermentation is especially important for human beings, as it is used to produce alcoholic beverages, bread, and many other everyday items that are consumed (Alba-Lois, 2010). On the other hand, lactic acid is a waste product of certain bacteria (Lactobacillales), which is utilized to create many dairy products such as yogurt and cheese. In addition, humans can resort to lactic acid fermentation when oxygen is limited, so it is used as an extra source to obtain oxygen. In our experiment we will be using yeast, a single-celled organism that utilizes sugar as a food source, and it produces energy substances through the breakdown of sugar molecules. Specifically, the type of sugar as a source of food, impacts the speed of fermentation in yeast. In this lab, we will calculate the rate of fermentation in yeast with different solutions of sugar, such as sucrose, fructose, and lactose with glucose being the control. It is important to humans that the yeast uses the best sugar source during fermentation, as it creates important everyday items we consume like bread, alcohol, and…

    Abstract – The problem that led to this experiment was that when antibiotics were mixed with yeast cells, the antibiotics decreased the yield of yeast cells. However, this is unexpected result because yeast is not a bacteria and therefore antibiotics should have no effect on them. The hypothesis that was tested was that antibiotics decrease the yield of yeast cells. In general the materials that were used in this experiment were a clean hemacytometer, a pipette, a solution of yeast with no antibiotics (culture A), and a solution of yeast…

    In CAM photosynthesis, CO2 is taken up only at night and is stored in vacuoles. This causes a buildup of oxaloacetate (acidic) - which we just met in C4 photosynthesis - in those vacuoles. The effect is to partition the initial uptake of CO2 and the rest of the Calvin Cycle over time (as opposed to the partition of these reactions in space that occurs in C4 photosynthesis). The stomata are open only at night, when it is relatively cool and humid; they stay closed during the hot, dry…

    Citrinin Lab Report

    The effect of aqueous extracts of four medicinal plant extracts on citrinin production from both fungi has been reported in Table 5 and Table 6. All the four plant extracts effectively decreased citrinin production ranging from 14.2 to 91.8% in P. notatum and 13.4 to 90.3% in A. niger. Amongst all the four extracts RhazyastrictaDecne was more efficient than all in inhibiting the citrinin production ranging from 22.4 to 91.8% in P. notatum and 32.6 to 93.2% in A. niger (Table 5 and 6). It was also found that in case of P. notatum the aqueous extract of Aervalanatawas more effective ranging from 16.3 to 87% while as in A. niger it was comparatively less the aqueous extract of Cleome amblyocarpa was effective ranging from 19.2 to 90.3% in A. niger while as it was 19.3 to 84.6% in P. notatum. This study for the first time reports inhibition of citrinin from medicinal plant extracts at these ranges. The present investigation showed that all the medicinal plant extracts were effective in decreasing the fungal biomass and citrinin production. Hence these plant extracts can be used as fungicides in the stored food grains as these microorganisms most commonly grow on storage and produce citrinin under these conditions. The study emphasizes on preventing the accumulation of toxic substances in food grains under…
