acid mine drainage (amd) containing high concentrations of iron and sulphate, low ph and variableconcentrations of heavy metals leads to many environmental problems. the concentrations of cu and mnare high in the amd of the sarcheshmeh porphyry copper mine, kerman province, south of iran. in thisstudy, the bio-remediation of cu and mn ions from acid mine drainage was investigated using two nati...

We synthesized oligomeric anthocyanins from grape skin-derived monomeric anthocyanins such as anthocyanidin and proanthocyanidin by a fermentation technique using Aspergillus niger, crude enzymes and glucosidase. The biosyntheses of the oligomeric anthocyanins carried out by the conventional method using Aspergillus niger and crude enzymes were confirmed by ESI-MS. The molecular weight of the s...

Glucose oxidase (GOx) has found wide range of industrial applications. Commercial GOx are produced from Aspergillus niger and selected strains of Penicllium species, however, these strains are associated with some drawbacks. Aspergillus niger produces predominantly intracellular GOx, which requires extra recovery processes thus incurs more processing cost while Penicillium sp. exhibits filament...

In spite of the taxonomy of the Aspergillus species of the Nigri Section being regarded as troublesome, a number of methods have been proposed to aid in the classification of this Section. This work aimed to distinguish Aspergillus species of the Nigri Section from foods, grains and caves on the basis in Polyphasic Taxonomy by utilizing morphologic and physiologic characters, and sequencing of ...

The present investigation deals with the kinetics of submerged citric acid fermentation by Aspergillus niger using blackstrap molasses as the basal fermentation media. A laboratory scale stirred fermentor of 15-L capacity having working volume of 9-L was used for cultivation process and nutritional analysis. Among the 10 stock cultures of Aspergillus niger, the strain GCBT7 was found to enhance...

Some oxadiazole derivatives were tested in vitro against Aspergillus parasiticus, Aspergillus flavus, Aspergillus niger, Fusarium solani, Fusarium moniliforme and Stachybotrys chartarum. All compounds showed the highest antifungal activity against S. chartarum. Among these compounds (3a-j), compounds 3a, 3c, 3d, 3e, 3i, 3j exhibited the same level of antifungal activity against all tested mold ...

A newly synthesized Nickel (II) tyrosine complex was screened as potential antimicrobial agent against a number of medically important bacteria (Bacillus subtilis, Streptococcus β-haemolytica, Escherichia coli, Shigella dysenterae) and fungi (Aspergillus fumigatus, Candida albicans, Aspergillus niger, Aspergillus flavus, Penicillium sp.) strains. were used for antifungal activity. The antimicro...

Elastolytic and elastase inhibitory activities were investigated for 13 strains of Aspergillus fumigatus, three strains of Aspergillus flavus and three strains of Aspergillus niger. Nine of the 13 strains of A. fumigatus and all strains of A. flavus demonstrated elastase activity (more than 1 unit ml(-1)). Six of the 13 strains of A. fumigatus and all strains of A. flavus expressed elastase inh...
