AMMONIUM OXIDATION BY CELL-FREE EXTRACTS OF ASPERGILLUS WENTII

Canadian Journal of Biochemistry, 1964
Cell-free extracts of Aspergillus wentii were found to catalyze the oxidation of ammonium to nitrate; small quantities of hydroxylamine and nitrite accumulated during the oxidation. The oxidations of hydroxylamine to nitrite and of nitrite to nitrate apparently took place through the respective cytochrome c reductases.

Aspergillus nidulans gfdB, Encoding the Hyperosmotic Stress Protein Glycerol-3-phosphate Dehydrogenase, Disrupts Osmoadaptation in Aspergillus wentii

Journal of Fungi (Basel, Switzerland)
The genome of the osmophilic Aspergillus wentii, unlike that of the osmotolerant Aspergillus nidulans, contains only the gfdA, but not the gfdB, glycerol 3-phosphate dehydrogenase gene. Here, we studied transcriptomic changes of A.

Production of amylase by a submerged culture ofAspergillus wentii

Folia Microbiologica, 1978
Soluble starch was hydrolysed to maltose by Aspergillus wentii Wehmer (IMI 17295). Studies on nutritional requirements of Aspergillus wentii for production of amylase revealed that the optimum conditions were achieved in fermentation culture medium containing 1% starch, and incubated at 20 degrees C for 3 days at pH 6.0.

The production of β-glucosidase in shake-flasks by Aspergillus wentii

Journal of Fermentation Technology, 1987
Abstract Studies in shake-flasks showed that Aspergillus wentii produces the maximum activity of β-glucosidase among the cultures tested. The activity against cellobiose was about 2–3 fold that against 4NPG. Aspergillus wentii produced a maximum activity of 16.5 U/ml in 14 days on malt extract.

An Inhibitor of Plant Growth-produced by Aspergillus wentii Wehmer

Nature, 1965
IN the course of an empirical screening programme we found that culture nitrates of Aspergillus wentii, grown on Raulin–Thom medium (5 per cent glucose) supplemented with 0.1 per cent Difco yeast extract, have a pronounced inhibitory effect on the growth of ‘Meteor’ pea seedlings.

Endoglucanase from the mixed culture of Trichoderma reesei and Aspergillus wentii

Bioprocess Engineering, 1990
The level of α-mannanase in mixed fungal culture of Trichoderma reesei, D1-6, and Aspergillus wentii, Pt 2804, affects the extracellular activities of cellulase. The endoglucanase component of the cellulase system is a glycoprotein having mannose and other sugars and sugaramines in its glycan moiety. Its activity is inhibited by α-mannanase.

Catalysis by β-glucosidase A ₃ of Aspergillus wentii

J. Chem. Soc., Perkin Trans. 2, 1980
(1)α-Deuterium kinetic isotope effects on Vmax. for hydrolysis of both β-D-glucopyranosylpyridinium ions and aryl β-D-glucopyranosides are in the range kH/kD 1.08–1.14, indicating that bond-breaking limits the rate of hydrolysis of both sets of substrates. The variation of kcat with aglycone acidity, expressed by log kcat=A+βlgpKa, is governed by a βlg

Ultraviolet induced mutations in Aspergillus wentii.

Acta microbiologica Polonica, 1979
Aspergillus wentii (IMI 17295) and its three nutritional mutant strains were irradiated with UV rays. New mutants obtained differed from the parent strains in colour of the conidia, growth factor requirements and amylase activity. Arginine deficient strains showed greater amylase activity.

Three new xanthone derivatives from an algicolous isolate of Aspergillus wentii

Magnetic Resonance in Chemistry, 2012
Three new xanthone derivatives, yicathin A (1), yicathin B (2), and yicathin C (3), and three known anthraquinone derivatives, alatinone (4), 1,5‐dihydroxy‐3‐methoxy‐7‐methylanthraquinone (5), and 5‐hydroxy‐1,3‐dimethoxy‐7‐methylanthraquinone (6), were isolated from the cultures of Aspergillus wentii pt‐1, an endophytic fungus isolated from the marine ...
