The exopolygalacturonase from Aspergillus tubingensis is also active on xylogalacturonan

Biotechnology and Applied Biochemistry, 1999
Apple‐pectin hairy regions were prepared from apple pectin by combined action of the recombinant Aspergillus niger enzymes endopolygalacturonase II and pectin methylesterase and the A. tubigensis exopolygalacturonase. Using this enzymically prepared pectin fraction, an additional activity of the A.

Assessment of the ochratoxin A production ability ofAspergillus tubingensis

Food Additives & Contaminants: Part A, 2012
Aspergillus tubingensis is a black Aspergillus frequently isolated from different agricultural products, including grapes. Conflicting results have been published in recent years about its ability to produce ochratoxin A (OTA), a potent nephrotoxic and carcinogenic mycotoxin. This study re-examined six A.

Primary Structure and Characterization of an Exopolygalacturonase from Aspergillus Tubingensis

European Journal of Biochemistry, 1996
From the culture fluid of the hyphal fungus Aspergillus tubingensis, an exopolygalacturonase with a molecular mass of 78 kDa, an isoelectric point in the pH‐range 3.7–4.4 and a pH optimum of 4.2 was purified. The enzyme has been characterized as an exopolygalacturonase [poly(1,4‐α‐d‐galacturonide)galacturonohydrolase] that cleaves monomer units from ...

Three new aflavinines from the sclerotia of aspergillus tubingensis

Tetrahedron, 1989
Abstract Three new metabolites with the aflavinine ring system (2–4) have been isolated from the sclerotia (key survival structures) of the fungus Aspergillus tubingensis (NRRL 4700), and their structures were assigned primarily through NMR studies.

Aspergillus tubingensis and Aspergillus niger as the dominant black Aspergillus, use of simple PCR-RFLP for preliminary differentiation

Journal de Mycologie Médicale, 2016
This work aimed to identify the species distribution of common clinical and environmental isolates of black Aspergilli based on simple restriction fragment length polymorphism (RFLP) analysis of the β-tubulin gene. A total of 149 clinical and environmental strains of black Aspergilli were collected and subjected to preliminary morphological examination.

Mycoremediation of Sulfamethoxazole and metabolic pathway by Aspergillus tubingensis strain

Biotechnology Letters
Over the last few decades sulfonamides are being prescribed on a large scale for treating human beings and livestock. Contaminants of sulfonamide antibiotics are present in various environments and these residues can enter the food web, leading to health threat.

Decolourisation and dephenolisation potential of selected Aspergillus section Nigri strains – Aspergillus tubingensis in olive mill wastewater

World Journal of Microbiology and Biotechnology, 2006
Aspergillus section Nigri strains Aspergillus aculeatus Ege-K 258, A.foeditus var. pallidus Ege-K156, A. niger Ege-K 4 and A. tubingensis Ege-K 265 were used to treat olive mill wastewater (OMW) in an investigation aimed at exploring their dephenolisation and decolourisation ability and, consequently, the economic feasibility of using any or all of ...

Mechanisms of interaction of chromium with Aspergillus niger var tubingensis strain Ed8

Bioresource Technology, 2014
Experiments were conducted to determine the mechanisms of interaction with chromium of Aspergillus niger var tubingensis strain Ed8 in batch culture and in bioreactor experiments. Results obtained in this work showed that the interaction of A. niger var tubingensis Ed8 with Cr(VI) is based mainly in a reduction process and also, secondly, in a sorption

Conversion of Fusaric Acid to Fusarinol by Aspergillus tubingensis: A Detoxification Reaction

Journal of Chemical Ecology, 2013
The fungus Fusarium oxysporum causes wilt diseases of plants and produces a potent phytotoxin fusaric acid (FA), which is also toxic to many microorganisms. An Aspergillus tubingensis strain with high tolerance to FA was isolated from soil and designated as CDRAt01. HPLC analysis of culture filtrates from A.
