Invasive aspergillosis typically afflicts immunocompromised patients, whereas pulmonary aspergilloma is a recognized complication of pre-existing cavitary lung disease in immunocompetent hosts. In both cases, the most prevalent pathogens are Aspergillus fumigatus and Aspergillus flavus. We describe a case of fatal hemoptysis from invasive Aspergillus niger infection in the setting of bullous lu...

Purpose Helleborus niger (Ranunculaceae), commonly known as Christmas rose, is used in anthroposophically extended cancer therapy in the adjuvant treatment of different entities and reduction of chemotherapy-associated side effects. Although Helleborus niger is widely used in anthroposophic medicine, there is a lack of scientific clinical and preclinical data and until now it is applied on an e...

α-Galactosidase production by the fungal strains Penicillium chrysogenum LN33 and Aspergillus niger M47 cultivated in shaking and stationary conditions using soya meal extract as nutrient medium was investigated. Submerged shake flask fermentation was preferred over stationary cultivation for P. chrysogenum LN33 as it gave a high α-galactosidase yield (4200U/l). Because of pellet formation the ...

The characteristics of growth, productivity and morphology varied with the mixing system and the applied agitation regime. In the first series of experiments, the flow characteristics of Aspergillus niger broth under different mixing conditions were analysed in a model bioreactor using RTS1 and ACS1. The kinetic energy E of flow fluctuations was measured in gassed and ungassed water and ferment...

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...

Ten fungal isolates from coffee beans were morphologically identified as Aspergillus niger, A. ochraceus and A. carbonari-us (N = 5, 3, and 2, respectively). Only one isolate, morphologically identified as A. niger, was unable to produce ochratoxin A (OTA). This may be a new species in the Aspergillus section Nigri. OTA levels in all the other isolates were above the limit of detection (0.15 mg...

Hibiscus rosasinensis is a medicinal plant species which grows in moist soil favorable for the growth of Aspergillus niger (fungus) too. But extract of Hibiscus rosasinensis does n’t shows inhibition zone against Aspergillus niger in PDA (Potato Dextrose Agar) media in microbiological evaluation. In other hand, the Allium fistulosum root extract having antifungal activity shows moderate zone of...

PHB degradation capabilities of seven species of Aspergillus namely Aspergillus niger, Aspergillus flavus, Aspergillus ochraceus, Aspergillus nidulans, Aspergillus terreus, Aspergillus fumigatus and Aspergillus parasiticus on the polymer produced by Rhodospseudomonas palustris KU003 were assayed . Among all the fungi investigated, the ability of A.niger to utilize the biopolymer was the highest...

MS liquid medium supplemented with 3 mg/l NAA and 1 mg/l BAP with pH 5.7 was used for suspension cultures. Suspension cultures subjected to biotic elicitors Aspergillus niger, Fusarium oxysporium, Rhizopus oryzae and Penicillium notatum induced increase in forskolin content. Among all the elicitors tried Aspergillus niger proved to be best elicitor at 5% CF which was 6 times higher than the con...
