The majority of mycotoxins produced by Aspergillus fungi are immunosuppressive agents, and their cytotoxicity may impair defense mechanisms in humans. The objective of the study was evaluation of the cytotoxicity of fungi isolated from an environment where inpatients with impaired immunity were present. The materials comprised 57 fungal strains: Aspergillus fumigatus, Aspergillus niger: Aspergi...

In this study, we examined the microbial population in different parts, gill, muscles and intestine region of Channa punctatus from two different fish culture farm. Based on their growth characteristics on specific culture media, the following human bacterial pathogen such as Achromobacter xylosoxidans (Gram +ve), Acinetobacter anitratus (Gram -ve), Bacillus subtilis (Gram +ve), Proteus vulgari...

Aspergillus luchuensis is known as an industrially important fungal species used for making fermented foods such as awamori and shochu in Japan, makgeolli and Meju in Korea, and Pu-erh tea in China. Nonetheless, this species has not yet been widely studied regarding mating-type genes. In this study, we examined the MAT1-1 and MAT1-2 gene ratio in black koji molds (A. luchuensis, Aspergillus nig...

Soil samples were collected from the different locations in Sathuragiri Hills (Western Ghats, Tamilnadu). The Total Fungal Counts in the soil samples of the different locations were analyzed. The percentage frequencies of occurrence of fungal isolates are identified. The fungal isolates were identified based on the morphological and cultural characteristics they were identified as Cladosporium ...

background: the antifungal activity of selenium nanoparticles (se nps) prepared by klebsiella pneumoniae has been reported previously for different fungi. in the present study, freshly prepared se nps produced by k. pneumoniae were purified and characterized by transmission electron microscopy and energy-dispersive x-ray spectroscopy (eds) and its post antifungal effects for two fungi were eval...

Aflatoxin contaminates foods including peanuts. Aflatoxin is a carcinogenic toxin mainly produced bty Aspergillus flavus. Other Aspergillus species that rarely produce aflatoxins are A. nomius and A. niger. Aflatoxin is associated with liver failure, hepatocellular carcinoma (HCC) and death. Recent studies have shown that peanuts in Kenya are highly contaminated with aflatoxins but information ...

Onychomycosis is a common nail infection caused by dermatophytes, while non-dermatophytes including Aspergillus spp. are causes of nail onychomycosis. Aspergillus niger is not common as a cause of nail onychomycosis. In the current study we present a 60-year-old woman with subungual onychomycosis due to Aspergillus niger mimicking a glomus tumor. Physical examination revealed right thumb had a ...

The present study aimed to assess and compare the ability to remediate synthetic textile and industrial wastewaters by Fenton treatment, a biological system and sequential treatments using Aspergillus niger (A. niger). All studied treatments were found to be effective in decolorization of the effluents under study. Fenton treatment followed by A. niger showed excellent potential for the maximum...

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...
