Isolation and Identification of a Strain of Aspergillus Tubingensis With Deoxynivalenol Biotransformation Capability [PDF]

International Journal of Molecular Sciences, 2008
Deoxynivalenol (DON) is one of the most common contaminants of various foodstuffs. A biotransformation system was used in order to lessen the toxicity of DON. A strain of Aspergillus (NJA-1) was isolated from soil and cultured in an inorganic salt medium containing DON. Bt2a/Bt2b primers were used to amplify the β-tubulin gene of NJA-1.

Sexual recombination in Aspergillus tubingensis

Mycologia, 2015
Aspergillus tubingensis from section Nigri (black Aspergilli) is closely related to A. niger and is used extensively in the industrial production of enzymes and organic acids. We recently discovered sexual reproduction in A. tubingensis, and in this study we demonstrate that the progeny are products of meiosis.

Biodegradation of polyester polyurethane by Aspergillus tubingensis

Environmental Pollution, 2017
The xenobiotic nature and lack of degradability of polymeric materials has resulted in vast levels of environmental pollution and numerous health hazards. Different strategies have been developed and still more research is being in progress to reduce the impact of these polymeric materials.

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.

Inverting character of α-glucuronidase A from Aspergillus tubingensis

Biochimica et Biophysica Acta (BBA) - General Subjects, 2000
Alpha-glucuronidase A from Aspergillus tubingensis was found to be capable of liberating 4-O-methyl-D-glucuronic acid (MeGlcA) only from those beechwood glucuronoxylan fragments in which the acid is attached to the non-reducing terminal xylopyranosyl residue.

Biosolubilization of poorly soluble rock phosphates by Aspergillus tubingensis and Aspergillus niger

Bioresource Technology, 2002
Three isolates of Aspergillus tubingensis and two isolates of Aspergillus niger isolated from rhizospheric soils were tested on solubilization of different rock phosphates. All the isolates of Aspergillus were capable of solubilizing all the natural rock phosphates. 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 ...

Identification of Aspergillus tubingensis causing pomegranate fruit rot in China

Australasian Plant Pathology, 2021
The fungus Aspergillus tubingensis is widely known from its use in industrial fermentation and other processes. More rarely, it is an opportunistic pathogen of humans or plants. In the present study, we found one rotten pomegranate fruit (Punica granatum) with black patches of rot and sporulation on the surface. Three A.

Interpretation of mtDNA RFLP variability among Aspergillus tubingensis isolates [PDF]

Antonie van Leeuwenhoek, 2006
Aspergillus tubingensis isolates collected from distant geographic areas were earlier classified into six groups on the basis of the mtDNA RFLP variability they exhibited (mtDNA types 2a-2f). In the present work, we investigated the reason for the intraspecific mtDNA variability and we describe here how this fungus, with a relatively small ...

Efficient immobilization behavior and mechanism investigation of Pb(II) by Aspergillus tubingensis

Biotechnology Letters, 2022
To understand the mechanism of Pb(II) immobilized by Pb(II)-tolerant microbes.Aspergillus tubingensis isolated from the lead-zine mine was investigated through surface morphology observation and multiple experimental analysis in order to elucidate the Pb(II) biosorption and immobilization behavior. The maximum Pb(II) uptake capacity of A.
