Which Species of Mold is Most
Successful in Transplanting
Itself into a New Environment
By Beau Levering and Taylor Yates
Introduction
Mold is a eukaryotic type of fungi. It uses spores as a
means of reproduction. These spores are extremely resilient.
Once landing on a suitable environment, it plants itself and
begins to feed and grow off of its host.
Some types of Fungi included yeast, mold, and
mushrooms.
Our Experiment
• Rationale: We are learning about mold
growth
• Purpose: We are trying to find out which
species of mold will be most successful in
transplanting themselves from one
environment to the next.
• Goal: We hope to successfully transplant
different species of mold from cheese,
tomato sauce, bread, and cottage cheese into
a different food medium
Experimental Design
IV: Type of mold
Aspergillus
Penicillium

DV: Amount of mold growth on new environment
Constants:
medium: spaghetti sauce
daily watering
Process
We will grow mold on 4 different foods;
cottage cheese, tomato sauce, cheese, and
bread. After enough mold growth has
occurred, we will transplant as many types
of mold into a plastic container next to
tomato sauce. We will then allow the mold
time to spread from its original food onto
the tomato sauce.
Types of Foods We Grow Our Molds On
(Before Growth)
Tomato sauce
Cheese
Cottage Cheese
Food with Mold Growth
Tomato Sauce
Cottage Cheese
Cheese
Bread
Analysis of Growth
Tomato Sauce: Variation of molds, but barely. Penicilum has
almost entirely overrun the tray. To put this in perspective, when
water is placed on the tray, its simply runs off the Penicilium.
Cottage Cheese: Penicillium growth exclusively.
Dutch Cheese: No mold growth.
Bread: Light Penicillium growth.
Results
We Identified 2 types of mold; Penicillium and Aspergillus.
This is the growth after four days after transplant.
Aspergillus
Penicillium
As you can see, there is Penicillium in our Aspergillus tray, partially this is due to lack
of a method for sterile technique. However, the Penicillium had overrun almost all of
the other molds in the sample we collected from (spaghetti sauce), which is why
Aspergillus is the only other mold we have.
Analysis of Transplants
(conclusion)
Aspergillus: Quickly grows, but fragile. Cannot survive when
competing with Penicillium for space.
Penicillium: Grows slower than Aspergillus, but when it begins
to produce spores, will easily take over a habitat with 1-3 days.
