Yeast is an ever-growing health issue, and concerns many people. Our environment is known to have yeast as a natural inhabitant and in many cases it is abundant in numbers. Yeast is not common in mold laboratory analysis and this cosmopolitan fungi goes undetected. The Florida Institute of Mold has written methods and protocols for the optimum recovery of yeast. In all types of sampling we have yeast recovered in the Stachybotrys Media from Micrology Laboratories. This recovery of yeast is not accomplished through traditional culture methods; liquid suspension is required and peptones, utilized as a stimulant, must be in the formula. Due to the characteristics of yeast growth, the growth that clearly excludes most mold forms of growth, distinct in color and growth morphology many yeast can be recognized as a yeast without formal identification. Identification is tricky and several culture attempts must be made so the yeast will grow in an identifiable form. Many times chemical fingerprinting is needed for true identification.
