In their monograph of the genus Aspergillus, Raper and Fennell () accepted species subdivided into 18 groups. The generic and species concepts were well circumscribed and this monograph is still valuable and by:   Auroglaucin and flavoglaucin are major end products of carbohydrate metabolism among members of the Aspergillus glaucus group. Striking quantities of these pigments are produced in both surface and submerged cultures. (2) Even after considerable growth has developed, aerobic conditions are essential for pigment formation. Cited by: 5. In Aspergillus nidulans, there are two putative glycerol 3‐phosphate dehydrogenases encoded by the genes gfdA and gfdB, while the genome of the osmophilic Aspergillus glaucus harbors only the ortholog of the A. nidulans gfdA gene. Our aim was to insert the gfdB gene into the genome of A. glaucus, and we reached this goal with the adaptation of the Agrobacterium tumefaciens‐mediated. Although Aspergillus glaucus is ubiquitous in warm moist environments, few cases of infections like IPA caused by the pathogen has been reported. Voriconazole might be one better choice to treat the diseases. However, the patient discharged voluntarily from the hospital without remission of symptoms after four days therapy and died one week later.

The Aspergillus glaucus group contains approximately 17 species (subject to continued molecular study and reassignment, I’m sure). Of these, some species are extremely xerophilic (need little or no water to survive) and as such, may be found in greater numbers in tropical to subtropical regions as opposed to temperate zones. The black aspergilli, Aspergillus section Nigri (Gams et al. ) includes species with uniseriate or biseriate conidial heads, spherical to pyriform vesicles, smooth-walled stipes and black or near black-coloured conidia. This group contains about 26 species with Aspergillus niger being the most common species isolated. Maja Peraica, in Environmental Mycology in Public Health, Ochratoxins. Ochratoxins are a group of mycotoxins produced by Penicillium verrucosum and various species of Aspergillus molds (Aspergillus alliaceus, Aspergillus auricomus, Aspergillus carbonarius, Aspergillus glaucus, Aspergillus melleus, Aspergillus niger) that contaminate crops in the field, leading to field and .

The occurrence of emodin, erythroglaucin, physcion, physcionanthrone, questin, catenarin, and catenarinmethyl ether in different species of the Aspergillus glaucus group (genus Eurotium) was investigated. So far catenarinmethyl ether (1, 4, 6-trihydroxymethoxymethylanthraquinone) has not been described as a natural product; it was therefore given the name rubrocristin.

However, although teleomorph forms of Aspergillus have been described in at least eight genera, Eurotium is arguably the most significant to humans as they are a common agent of food spoilage [1]. There are 81 species.
