Six fungal isolates were selected from the rhizosphere of black pepper (Piper nigrum L.) plants and were tested in vitro for their plant growth promoting (PGP) abilities in the soil. The species of Aspergillus selected were tested for the siderophore production, indole acetic acid (IAA) production, catalase enzyme activity and biological control of pathogens through antagonism. The results indi...

Within the family Solanaceae, tribe Hyoscyameae comprises eight genera distributed across Eurasia. Despite a few attempts to understand relationships within this tribe, affiliations among most remain unresolved. Recently, complete chloroplast genomes from several species of were published, enabling phylogenomic inferences. We sequenced plastome Scopolia carniolica, second genus be reported. Gen...

Plant Flavonoids are considered as naturally occurring bioactive compounds. In the present study, chitosan and Aspergillus niger elicitors were used as chemical and fungal elicitors, respectively. The cell suspension culture of Andrographis paniculata (Burm. f.) Nees was established in 50 ml MS media supplemented with 2,4-D: BAP (1.0:0.5 mg/l) and treated with chitosan and Aspergillus niger eli...

This study investigates effects of six kenaf cultivars named Cubano, Niger, Cubano 2032, 9277, 7551, and 7566 and three harvesting time stages on the properties of pulp and handsheet paper made from kenaf. Six cultivars of an Iranian kenaf (Hibiscus Cannabinus L.), were planted on 19 May 2007, and harvested after 85, 105, and 135 days. It was understood that with the increase of plant age, fibe...

the removal of uranium and any other heavy metals from wastewater might be achieved via several chemical or physical treatment techniques. biosorption process has been considered as a potential alternative way to remove contaminants from industrial effluents. moreover the surface of biosorbent was characterized by sem. the biosorption characteristics of uranium (vi) on pretreated a. niger were ...

BACKGROUND The industrially relevant filamentous fungus Aspergillus niger is widely used in industry for its secretion capabilities of enzymes and organic acids. Biotechnologically produced organic acids promise to be an attractive alternative for the chemical industry to replace petrochemicals. Itaconic acid (IA) has been identified as one of the top twelve building block chemicals which have ...

Out of 12 fungal strains, two fungal strains, namely Aspergillus flavus AT-2 and Aspergillus niger AT-3, were found to produce maximum cellulase production. The CMCase activities of A. flavus AT-2 and A. niger AT-3 under state solid fermentation (SSF) conditions were of 42.69 and 40.08%, respectively, which was higher than those obtained under submerged fermentation (SmF) conditions. A fungal i...
