1 Farley Conor Farley BMZ Lab Section BA Lenna Odstroka 30 October 2011 There Can Only Be One Fungi Hypothesis: In basic solution, the sample of Aspergillus niger will extrapolate the sample of Aspergillus flavus, due to a more aggressive growth rate. Results: The average initial growth rates of each fungal culture drawn from six trials and the class data were as follows: A. niger had an average growth rate of 4.71 cm squared per day, A. flavus had an average growth rate of 2.42 centimeters squared per day, and P. camembertii had an average growth rate of 2.31 centimeters squared per day (Table 1). Three separate Petri dishes were used in this experiment as the experimental samples, with a combination of fungi samples from Aspergillus niger and Aspergillus flavus . The three experimental dishes were treated with a basic solution to monitor growth rate of both fungal species, in regards to the hypothesis stated above. In all three dishes, A. flavus actually extrapolated A. niger completely, with no trace of A. niger to be measured. In Dish 1, A. flavus was measured at 46 cm squared after sitting for seven days, and the growth rate of this sample was measured at 1.64 cm squared per day (Table 2). The sample of A. flavus in Dish 2 was measured at 12 cm squared after sitting for

2 seven days, and the growth rate of this sample was measured at 0.429 cm squared per day (Table 2). Finally, Dish 3 of the experimental plates held a sample of A. flavus measured at 45 cm squared, after sitting for seven days, with a growth rate of 1.61 cm per day

    As a current student on this bumpy collegiate pathway, I stumbled upon Course Hero, where I can find study resources for nearly all my courses, get online help from tutors 24/7, and even share my old projects, papers, and lecture notes with other students.

    I cannot even describe how much Course Hero helped me this summer. It’s truly become something I can always rely on and help me. In the end, I was not only able to survive summer classes, but I was able to thrive thanks to Course Hero.

    The ability to access any university’s resources through Course Hero proved invaluable in my case. I was behind on Tulane coursework and actually used UCLA’s materials to help me move forward and get everything together on time.
