Culturable Air Sampling

Overview Culturable air sampling is one of the most common methods of volumetric air sampling. The sampler works by drawing measured volumes of air through an instrument that contains a petri dish (or dishes) with culture media. Spores that impact onto the plate are then allowed to incubate and grow, after which the colonies may […]

Mold Growth & Sporulation in Buildings – Part 2

    Each stage of fungal growth (spore germination, vegetative growth, sporulation) has a specific set of conditions that is optimal. Important conditions in this set are nutrient types and concentrations, light, temperature, oxygen and water availability. Water availability (i.e., water activity) is one of the most important of these. Each fungus has optimal water activities […]
