Coprogen is a hnear trihydroxamate produced by Penicillium species and Neurospora crassa and was first isolated and characterized by Hesseltine and coworkers . Coprogens are predominantly produced by fungi species and frequently several coprogens are produced by the same species. Coprogen is composed of Af -acyl-A -hydroxy-L-ornithine, anhydromevalonic acid and acetic acid.

Genes for pyruvate decarboxylases have been isolated from yeasts and fungi such as Saccharomyces cerevisiae [86-90], Hanseniaspora uvarum [91], Klyveromyces marxianus [92], Klyveromyces lactis [93], Neurospora crassa [94], Aspergillus parasiticus [95], plants, like maize (Zea maize) [96,97], rice (Oryza sativa) [98], tomato (Lycopersicon esculentum) [99,100], pea (Pisum sativum) [101], and tobacco (Nicotiana tabacum) [102] and from the bacterium Zymomonas mobilis [103-106].

Several decades ago, the earliest genetic work in molybdenum enzymes identified mutants of two fungi, Aspergillus nidulans (125) and Neurospora crassa (126) that lacked all molybdenum enzyme activities, specifically, nitrate reductase, XDH, and aldehyde oxidase. The mutant N. crassa produces an... 

The predominant class of intracellular iron-storage compounds is represented by ferritin in eukaryotes and bacterioferritin in prokaryotes (see Iron Proteins for Storage Transport their Synthetic Analogs). In various in vivo Mdssbauer spectroscopic studies on siderophore uptake in fungi, it was realized that siderophores can also function as intracellular iron-storage compounds. In the ascomycete Neurospora crassa, the transport siderophore coprogen represents an intracellular transient iron pool. A major part of coprogen-bound iron is transferred to a... 

Crook and Johnston and Martin and Adams were unable to find uronic acids in the cell walls of fungi. However, 2 % of a glucuronic acid was detected in the dry cells of Dactylium dendroides, and lesser proportions in Aspergillus niger (0.1 %), Penicillium album (0.2%), a Fusarium sp. (0.5%), and an Alternaria sp. (0.7%). Glucuronic acid residues are apparently present in the cell walls of Neurospora crassa. ... 

Dry citrus peels are rich in pectin, cellulose, and hemicellulose and may be used as a fermentation substrate. Production of multienzyme preparations containing pectinolytic, cellulolytic, and xylanolytic enzymes by the mesophilic fungi A. niger BTL, Fusarium oxysporum F3, Neurospora crassa DSM 1129, and Penicillium decumbens under SSF on dry orange peels was enhanced by optimization of initial pFI of the culture medium and initial moisture level (Mamma et al., 2008). Under optimal conditions A. niger...
