Have you ever wondered how fungal mycelium in soil impacts climate change?

My name is Lily Truong and in BIO299, I dug into the fascinating world of fungal decomposition to uncover how different types of mycelium break down under various climate conditions and what that means for carbon storage in soil—an essential factor in managing climate change.

The research focused on the decomposition of two distinct types of fungal mycelium: melanized (black) and non-melanized (white). By studying their behavior across diverse climate gradients and plant compositions, we aimed to understand how factors like temperature and precipitation influence the breakdown of fungal necromass (dead fungal material) and its effect on carbon sequestration. Over three intensive weeks, I analyzed approximately 150 soil samples, spending about eight hours a day weighing, transferring, and preparing them for freeze-drying to ensure accurate decomposition rate analysis.

My main role involved meticulously transferring tiny fragments of fungal necromass from it’s teabag into falcon tubes—a tedious but crucial step in achieving reliable results. After that i weighed the sample before freeze-drying and after. This hands-on work sharpened my precision and gave me a newfound appreciation for the intricate details of experimental biology.

Through this experience, I gained a deeper understanding of how small-scale biological processes, like fungal decomposition, connect to global challenges such as climate change. Never would I have guessed that soil and decomposition could be so captivating, but after a semester immersed in this project, I’ve developed a profound respect for the hidden dynamics of the underground world.

The project not only helped me refine my lab skills but also taught me the importance of communication with your superiors—whether it’s through a scientific report or a poster. I’m excited to apply everything I’ve learned in future research.

And hey, who knew fungi could play such a big role in fighting climate change?
