Mold Remediation Certification Practice Exam

What type of nutrient does Stakey grow on?

1. Starch

2. Cellulose

3. Glucose

4. Protein

The correct answer is: Cellulose

Stakey, a term often used in discussions of certain mold or fungal species, typically thrives on cellulose as its primary nutrient. Cellulose is a complex carbohydrate that forms the structural component of plant cell walls, making it an abundant source of energy for many fungi. When Stakey breaks down cellulose through enzymatic processes, it is able to utilize the components for growth and reproduction. Fungi like Stakey play a crucial role in the ecosystem by decomposing cellulose, which is not digestible by many other organisms. This ability not only allows fungi to flourish but also aids in nutrient cycling within the environment, contributing to the breakdown of plant materials and the release of carbon back into the soil. In contrast, the other options listed do not represent the primary nutrient source for Stakey. Starch is another carbohydrate but is not typically the preferred choice for cellulosic fungi. Glucose, while an important simple sugar for energy in many organisms, is usually obtained as a breakdown product of more complex carbohydrates like cellulose. Protein serves as a macronutrient but is not a primary growth medium for Stakey, which relies on the degradation of cellulose instead. Understanding the nutritional preferences of fungi is pivotal for effective mold remediation and management strategies.
