The biosynthesis of terpenoids in Gibberella fujikuroi

, 1987
The aim of this work was to study the terpenoid biosynthesis and its regulation in the fungus Gibberella fujikuroi. This was facilitated by the use of a number of mutants of G. fujikuroi produced using UV radiation or N-methyl-N'-nitrosoguanidine and selected mainly by mutation in colour and photoregulation (Avalos et al., 1985). A separation procedure

Carotenoid mutants of Gibberella fujikuroi

Current Genetics, 1987
The orange pigment neurosporaxanthin colours the mycelia of wild Gibberella fujijuori (Fusarium monifliforme) grown in the light, but is barely detectable in the dark. We have isolated carotenoid mutants from conidia exposed to N-methyl-N′-nitro-N-nitroso-guanidine and other mutagens.

Bikaverin and norbikaverin, benzoxanthentrione pigments of Gibberella fujikuroi

J. Chem. Soc. C, 1971
The chemical and spectroscopic characteristics of bikaverin and norbikaverin, two hydroxy-quinonoid benzoxanthones isolated from Gibberella fujikuroi and other Fusarium spp., are fully consistent with the established structures. Bikaverin forms two series of isomeric O-alkyl and O-acyl derivatives corresponding to tautomeric forms of the parent hydroxy-

The transformation of steviol by gibberella fujikuroi

Tetrahedron, 1968
Abstract Steviol (I) is converted to 6α,7β,13-trihydroxy-(—)-kaur-16-en-19-oic acid 9 → 6α lactone (II) by Gibberella fujikuroi.

THE KINETICS OF METABOLISM OF GIBBERELLA FUJIKUROI IN STIRRED CULTURE

Canadian Journal of Microbiology, 1964
Some aspects are described of the kinetics of the growth of Gibberella fujikuroi in nitrogen-limited media containing either ammonium nitrate, ammonium acetate, ammonium tartrate, urea, or glycine. Also varied were inoculum size, agitation rate, pH, and initial concentrations of glucose and nitrogen source.

Chemical modification of carotenogenesis in Gibberella fujikuroi

Phytochemistry, 1986
Abstract The wild type of the fungus Gibberella fujikuroi has no carotenoids in the dark and only moderate amounts in the light. The deep-orange mutant SG22 accumulates large amounts of carotenoids both in the light and the dark. The predominant compound is always neurosporaxanthin.

Regulation of secondary biosynthesis in Gibberella fujikuroi

Transactions of the British Mycological Society, 1974
Comparisons between submerged batch and chemostat fermentations of Gibberellafujikuroi show that major features of batch culture development relate directly to the degree of limiting substrate depletion and the corresponding growth rate. So-called secondary biosynthetic processes (mycelial carbohydrate accumulation, bikaverin and gibberellin synthesis)

The isolation of some metabolic products of Gibberella fujikuroi

Archives of Biochemistry and Biophysics, 1962
Abstract A number of compounds were isolated from the mother liquor, which remained after the separation of crystalline gibberellin. Their properties and derivatives are described and their possible presence in fermentation liquors of Gibberella fujikuroi is discussed.

THE METABOLISM OF GIBBERELLA FUJIKUROI IN STIRRED CULTURE

Canadian Journal of Microbiology, 1961
The growth of Gibberella fujikuroi in stirred culture was studied. Media were designed in which the initial concentrations of glucose (G), nitrogen (N), phosphorus (P), and magnesium (M) were varied so that the first nutrient was exhausted at a selected dry weight, and the remaining nutrients in all available sequences thereafter.
