The solid waste of sago industry using cassava was fermented by Aspergillus niger, Aspergillus terreus and Rhizopus stolonifer in solid state fermentation. Cassava waste contained 52 per cent starch and 2.9 per cent protein by dry weight. The amylase activity was maintained at a high level and the highest amylase activity was observed on the 8(th) day in R. stolonifer mediated fermentation. R. ...

The fungi isolated from 100 samples of flue-cured tobacco from 12 markets in 2 tobacco belts comprised 11 genera, including 10 species of Aspergillus. The mean percentage per sample isolated from 62 samples of tobacco from Middle Belt markets was Alternaria, 40.6%; Aspergillus niger, 47.8%; Aspergillus repens, 38.0%; and Penicillium, 25.8%. The mean percentage per sample isolated from 38 sample...

This study was conducted to evaluate fungus, Aspergillus niger, as probiotics in broiler chickens. The Chickens were divided into 4 treatments with average weight (375± 4 g). First treatment as control fed control diet and other chicks were fed diets supplemented with Aspergillus niger at the levels of 0.01, 0.05 and 0.1%. The birds were fed experimental diets until 27 d of age to evaluate the ...

Two inhibitors of CD45 tyrosine phosphatase, dihydrocarolic acid (1) and penitricin D (2), were isolated from a fermentation broth of the fungus Aspergillus niger and purified by HSCCC (high speed countercurrent chromatography) followed by HPLC. The structures were determined by NMR. The inhibitory activities of both compounds were specific to tyrosine phosphatases.

This work aims at optimizing the high cell density fungal cultivation for producing large quantities of fungal biomass to be used in azo dye residues bioremediation. In our previous studies the efficacy of using certain fungal strains to decolorize a range of commercial textile dyes of different structures (azo, disazo) were investigated. Several promising fungal strains belonging to Aspergillu...

Seventy-three fungal species belonging to forty-three genera were isolated from 40 samples of Saccharrum officinarum (collected from Naage-Hamadi canal in Qena Governorate, Egypt). Aspergillus, Trichoderma, Mucor and Pythium were the most common genera on the two isolation media. The dominant species of Aspergillus were A. niger, A. flavus, A. ustus, A. terreus and A. wentii. Some species were ...

The study is concerned with the isolation and screening of Aspergillus niger strains for the biosynthesis of acid protease using solid state fermentation. Thirteen A. niger strains capable of producing proteases were isolated from the soil. Of all the isolates, Aspergillus niger IHG9 was found to be the best producer of protease. Different agricultural by-products were evaluated as fermentation...

Oxalic acid produced by Aspergillus niger under submerged conditions in this work. Optimization done with different sources of carbon, nitrogen, minerals and at different pH then biomass production done of Aspergillus niger under submerged conditions for 7 days at room temperature. Further supernatant taken for titration and mycelium for oxaloacetate acetylhydrolase determination by SDS-PAGE. K...
