IDENTIFICATION OF FUNGICOLOUS FUNGI OF IRAN. II. TELEOMORPHS BELONGING TO THE GENUS

Three Hypomyces and one Cladobotryum species are studied and reported as new records and also new anamorph/teleomorph connections of fungicolous fungi for Iran. Anamorphs of two species H. aurantius and H. rosellus (Cladobotryum varium and C. dendroides, respectively) have already been reported from Iran. The anamorph/teleomorph association of H. polyporinus/C. clavisporum was also found and wa...

Pigments and citrinin biosynthesis by fungi belonging to genus Monascus.

Citrinin is a mycotoxin, which is produced by fungi belonging to the genus Monascus, known in biotechnology as producers of azaphilone pigments. The relation between biosynthesis of these secondary metabolites was investigated in different species of the genus Monascus in batch-culture at the following cultivation conditions: T = 28 degrees C, agitation 220 rpm, and a medium, which induce citri...

Hydroxylation of steroids at carbon 21.

Hydroxylation of steroids in V&O at carbon atom 21 by adrenal tissue preparations has previously been reported by Plager and Samuels (l), Hayano and Dorfman (2), and the present authors (3). The former workers described a system consisting of a 20,000 X Q supernatant fraction of beef adrenals which effected hydroxylation in this position of progesterone and ita derivatives in the presence of ad...

Hydroxylation of deoxyguanosine at the C-8 position by ascorbic acid and other reducing agents.

The C-8 position of deoxyguanosine (dGuo) was hydroxylated by ascorbic acid in the presence of oxygen (O2) in 0.1 M phosphate buffer (pH 6.8) at 37 degrees C. Addition of hydrogen peroxide (H2O2) remarkably enhanced this hydroxylation. The Udenfriend system [ascorbic acid, FeII, ethylenediaminetetraacetic acid (EDTA) and O2] was also effective for hydroxylation of dGuo in high yield. Guanine re...

Carbazole hydroxylation by the filamentous fungi of the Cunninghamella species

Nitrogen heterocyclic compounds, especially carbazole, quinolone, and pyridine are common types of environmental pollutants. Carbazole has a toxic influence on living organisms, and the knowledge of its persistence and bioconversion in ecosystems is still not complete. There is an increasing interest in detoxification of hazardous xenobiotics by microorganisms. In this study, the ability of thr...
