Production and characterization of a thermostable antifungal chitinase secreted by the filamentous fungus Aspergillus niveus under submerged fermentation
(Springer, 2018-08-10)
The filamentous fungus Aspergillus niveus produced extracellular antifungal chitinase when cultured under submerged fermentation (SbmF) using crab shells as the carbon source. Maximal chitinase production was achieved at ...
Heterologous expression of an Aspergillus niveus xylanase GH11 in Aspergillus nidulans and its characterization and application
(ELSEVIER SCI LTD, 2011)
A xylanase was cloned from Aspergillus niveus and successfully expressed in Aspergillus nidulans (XAN). The full-length gene consisted of 890 bp and encoded 275 mature amino acids with a calculated mass of 31.3 kDa. The ...
Characterization of an extracellular β-d-fructofuranosidase produced by Aspergillus niveus during solid-state fermentation (SSF) of cassava husk
(2018-02-01)
β-d-Fructofuranosidases are biotechnologically important enzymes produced by various organisms. Here, Aspergillus niveus produced an extracellular β-d-fructofuranosidase during SSF of cassava husk. This enzyme was purified ...
Properties of a purified thermostable glucoamylase from Aspergillus niveus
(SPRINGER HEIDELBERG, 2009)
A glucoamylase from Aspergillus niveus was produced by submerged fermentation in Khanna medium, initial pH 6.5 for 72 h, at 40A degrees C. The enzyme was purified by DEAE-Fractogel and Concanavalin A-Sepharose chromatography. ...
Properties of a purified thermostable glucoamylase from Aspergillus niveus
(Springer, 2009-12-01)
A glucoamylase from Aspergillus niveus was produced by submerged fermentation in Khanna medium, initial pH 6.5 for 72 h, at 40A degrees C. the enzyme was purified by DEAE-Fractogel and Concanavalin A-Sepharose chromatography. ...
Purification and biochemical characterization of a novel alpha-glucosidase from Aspergillus niveus
(SPRINGER, 2009)
An extracellular alpha-glucosidase produced by Aspergillus niveus was purified using DEAE-Fractogel ion-exchange chromatography and Sephacryl S-200 gel filtration. The purified protein migrated as a single band in 5% PAGE ...
Tunicamycin inhibition of N-glycosylation of alpha-glucosidase from Aspergillus niveus: partial influence on biochemical properties
(SPRINGER, 2010)
Treatment of Aspergillus niveus with 30 mu g tunicamycin/ml did not interfere with alpha-glucosidase production, secretion, or its catalytic properties. Fully- and under-glycosylated forms of the enzyme had similar molecular ...
The fungal metabolite eugenitin as additive for Aspergillus niveus glucoamylase activation
(ELSEVIER SCIENCE BVAMSTERDAM, 2012)
Endophytic microorganisms live inside tissues of host plants apparently do not causing warning to them, and area promising source of bioactive molecules as antimicrobial and antitumoral drugs. In this work, we report the ...
Production of beta-fructofuranosidases by Aspergillus niveus using agroindustrial residues as carbon sources: Characterization of an intracellular enzyme accumulated in the presence of glucose
(ELSEVIER SCI LTD, 2009)
The production of beta-fructofuranosidases by Aspergillus niveus, cultivated under submerged fermentation using agroindustrial residues, was investigated. The highest productivity of beta-fructofuranosidases was obtained ...
Use of Cassava Peel as Carbon Source for Production of Amylolytic Enzymes by Aspergillus niveus
(BERKELEY ELECTRONIC PRESS, 2009)
Aspergillus niveus produced high levels of alpha-amylase and glucoamylase in submerged fermentation using the agricultural residue cassava peel as a carbon source. In static conditions, the amylase production was substantially ...
