The minimal inhibitory concentrations (MICs) of lucknomycin, a new polyenic derivative, were determined for 101 clinical isolates of Candida, 38 clinical or environmental strains of Aspergillus fumigatus, and 30 isolates of A. niger. The most susceptible species were Candida albicans and Candida tropicalis (mean MIC, 0.4 micrograms/ml). Aspergillus spp. were less susceptible, with mean MICs of ...

The biotransformation of sucrose to fructooligosaccharides was investigated using the catalytic action of fructosyltransferase originated from marine Aspergillus niger, using whole cell immobilization. The biomass production and enzymatic reaction were carried out in shake flask. A fructosyltransferase enzyme producing fungi locally isolated from sea water from South East cost of India, by usin...

aspergillus species (a flavus and a niger) are important sources of inhalant allergens. current  diagnostic  modalities  employ  crude  aspergillus  extracts  which  only  indicate  the source to which the patient has been sensitized, without identifying the number and type of allergens in crude extracts. we report a study on the identification of major and minor allergens of the two common air...

Leaf spot was found on field bindweed (Convolvulus arvensis L.) in Shihezi City, Xinjiang Province, China, during the summer of 2015. Pathogens were isolated from the infected leaves of field bindweed and identified as Aspergillus niger based on morphological and molecular analyses (internal transcribed spacer rDNA and β-tubulin gene). A pathogenicity test confirmed that Aspergillus niger cause...

In an effort to develop alternate techniques to recover metals from waste electrical and electronic equipment (WEEE), this research evaluated the bioleaching efficiency of gold (Au), copper (Cu) and nickel (Ni) by two strains of Aspergillus niger in the presence of gold-plated finger integrated circuits found in computer motherboards (GFICMs) and cellular phone printed circuit boards (PCBs). Th...

Aflatoxin B₁, a type of highly toxic mycotoxin produced by some species belonging to the Aspergillus genus, such as Aspergillus flavus and Aspergillus parasiticus, is widely distributed in feed matrices. Here, coumarin was used as the sole carbon source to screen microorganism strains that were isolated from types of feed ingredients. Only one isolate (ND-1) was able to degrade aflatoxin B₁ aft...
