Aspergillus fungus

Photolysis of hydiroxylated polymers E, F, G, benzylated polymers H and I, and poly(piperazinyl sebacamide) J all resulted in crosslinking as the polymer samples became insoluble after photolysis. Interestingly enough, however, with the exception of polymer H, all polymer samples were found to be better carbon nutrients for the fungus Aspergillus niger after photolysis. 

Compounds identified as cell cycle inhibitors are Trp-Pro DPK alkaloids isolated from the fungus Aspergillus fumigatus, namely, spirotryprostatin A and spirotryprostatin These compounds show potential as M-phase inhibitors of the mammalian cell cycle. ... 

Chlordane did not degrade in settled domestic wastewater after 28 d (Tabak et al., 1981). Chlordane was metabolized by the fungus Aspergillus nigerhul it was not the main carbon source (Iyengar and Rao, 1973). 

In the filamentous fungus, Aspergillus nidulans, NIMA (never in mitosis, gene A) kinase phosphorylates H3 at Ser-10 [48]. At mitosis NIMA kinase association with chromatin increases and following metaphase NIMA locates to the mitotic spindle and spindle pole bodies. A human NIMA-related kinase (Nek6) was identified as a putative mitotic HI and H3 kinase [49]. 

The aflatoxins are rather unpleasant fungal toxins. At high levels they can cause severe liver damage in animals and humans, and at lower levels they are implicated in liver cancer. These toxins are produced by the fungus Aspergillus flavus, a common contaminant on nuts and grains. Aflatoxin Bi is the most commonly encountered...

It was subsequently discovered that lucanthone is metabolized in the body in part to hycanthone (30), a compound with enhanced schistomacidal activity. The relatively high biologic activity of lucanthone in experimental animals compared to man was subsequently attributed to the inefficient hydroxylating system present in man for this biochemical conversion.Microbiologic oxidation of lucanthone by fermentation with the fungus Aspergillus scelorotium affords hycanthone. ... 

An interesting new penta-O-substituted flavanone is 8-hydroxyhesperetin (5,7,8,3 -tetrahydroxy-4 -methoxyflavanone, 20), which was produced by the fungus Aspergillus saitoi...

Aflatoxins, e.g., 40, comprise a family of related products that are elaborated by the fungus Aspergillus flavus and end by contaminating the food, such as peanuts, upon which the fungus grows. Several aflatoxins, notably B, and Gj, become covalently hydrated in the mammalian liver to give the true toxin 41, which is a hemiacetal. This change...
