Indoor Air Hygiene - Microbiological

In addition to outdoor air, water, and soil, our living space also includes the indoor areas in which we spend a large part of our time.
Pollutants in indoor spaces can be dust-bound or airborne. They can have a lasting impact on health, so testing for potential contaminants can be an important part of preventive health care.

Molds and bacteria


The popular term "molds" includes numerous different species of fungi that form a typical mycelium with spore carriers that are visible to the naked eye as a downy coating. Molds, yeasts, and bacteria occur ubiquitously in our environment and play an essential role in the biological material cycle. They break down dead organic residues and make the resulting substances available to the food chain of higher plants and animals.
Molds, as a natural component of our environment, are also always present indoors as a background contaminant. However, when increased moisture allows mold to colonize materials beyond the background level, it is referred to as mold infestation or mold damage. In particular, when high levels of spores are released into indoor air, this can result in direct adverse health effects to the occupants of the space.
The assessment of mold damage requires extensive expertise and experience in order to be able to make statements on the health relevance and urgency of remediation. In addition to a detailed consultation, we offer inspections, sampling, analysis in our own laboratory, and an evaluation of the results according to the current standards in compliance with current guidelines (e.g. Federal Environmental Agency) by our experienced and trained staff.
Our services include:
  • Determination of molds and bacteria after cultivation (air, surface, smear and material samples)
    • Determination of total spore count (direct microscopy)
    • Foil contact samples (direct microscopy)
    • Determination of fecal bacteria after cultivation (e.g. after wastewater damage)
