Experiment with Microbial Metabolism Science Projects (6 results)

Discover how microorganisms generate energy to stay alive by experimenting with conditions that allow them to thrive or inhibit growth. Explore the chemistry behind the bubbles that yeast produce as they break down sugar, or the movement of slime mold as it senses its environment.

Science Fair Project Idea
While looking at a package of dry yeast it is hard to believe that the package has organisms in it that are alive. But add the right ingredients and presto, the mixture becomes a bubbly, oozing, mess of life! What are the right ingredients? What does that yeast need to become active? Do this science project and figure it out for yourself! Read more

Did you ever wonder how yeast makes bread dough rise? This project will show you what yeast does to make this happen. You'll also investigate the conditions yeast needs to grow. Read more
Science Fair Project Idea
There is nothing quite like the smell of fresh-baked bread to make your mouth water! As any baker can tell you, you cannot bake bread without yeast. Yeast actually eat sugar so that they can reproduce and make more yeast, and make bread dough rise. But can they use sugar substitutes to do this? In this science project you will get to investigate how well yeast grow with sugar substitutes as a food source. Pass the butter, please! Read more
Science Fair Project Idea
This is a straightforward project on glucose metabolism in yeast. You will grow yeast under aerobic and anaerobic conditions and measure carbon dioxide output to assess metabolic efficiency. Read more

Have you ever wondered how antibiotics and other medicines are able to stop dangerous infections? How do such medications kill microorganisms without in general harming the person the microorganisms are infecting? Because many different types of microorganisms can infect us, we have had to develop an amazing number of ways to deal with these harmful microbes. Fungal infections can be particularly dangerous, but we have developed many different antifungal medications that can usually deal with… Read more

In this biology science fair project, you will observe how the Physarum polycephalum (P. polycephalum) organism responds to various amounts of glucose. P. polycephalum is easy to grow in a petri dish and responds in complex ways to its environment. Will it grow toward the chemical as it looks for a meal, or will it flee, trying to avoid further contact? Try this science fair project to learn more about chemotaxis in the fascinating Physarum polycephalum. Read more
