This globally occurring mold species is usally found on rotting organic waste, as well as in soil and on manure. The species plays a comparatively minor role indoors. Due to its low water activity, Aspergillus clavatus can also occur on dry substrates and is therefore classified as a xerophilic mold.

At GBA Group, we have more than 30 years of experience in environmental analysis. Our state-of-the-art laboratories ensure fast and competent environmental analysis services.

For a long time, the species Stachybotrys chartarum played a minor role in the analysis of indoor-relevant molds. Since the species grows relatively slowly, it is often strongly underrepresented in cultivating indoor air measurements because it is displaced by fast-growing genera (e.g. Aspergillus and Penicillium).

But what actually happens during sampling and how does the sample get from the environment to the laboratory?

We lift the curtain and offer an insight into the daily work at our environmental sites. To do so, we would like to share some impressions with you: From sampling to analysis in our state-of-the-art lab.

Penicillium griseofulvum was first described morphologically by Dierckx in 1901 and recognized as a distinct species within the genus Penicillium. The morphological identification of Penicillium griseofulvum is comparatively simple as it is one of the few interior Penicillium species to form tertiary and quarterverticillate spore carriers. That means, from one main axis branch up to three lateral axes, which end in terminal metulae and phialides.
