Fermentation is one of the industrially important processes for the development of microbial metabolites that has immense applications in various fields. This has prompted to employ fermentation as a major technique in the production of phytase from microbial source. In this study, a comparison was made between submerged (SmF) and solid-state fermentations (SSF) for the production of phytase fr...

BACKGROUND Laccase-like multicopper oxidases have been reported in several Aspergillus species but they remain uncharacterized. The biocatalytic potential of the Aspergillus niger fungal pigment multicopper oxidases McoA and McoB and ascomycete laccase McoG was investigated. RESULTS The laccase-like multicopper oxidases McoA, McoB and McoG from the commonly used cell factory Aspergillus niger...

This study evaluated the synergism between several P-solubilizing fungi isolates and arbuscular mycorrhizal fungi to improve clover ( Trifolium pratense) growth in the presence of Araxá apatite. Clover was sown directly in plastic pots with 300g of sterilized washed sand, vermiculite and sepiolite 1:1:1 (v:v:v) as substrate, and grown in a controlled environment chamber. The substrate was ferti...

A cadmium tolerant strain of Aspergillus niger and a lead tolerant strain of Rhizopus arrhizus were studied for distribution of accumulated toxic heavy metals in the mycelia in comparison to wild type strains. Accumulated cadmium in the cell wall fractions of cadmium tolerant Aspergillus niger was more than the wild type strain. Cytosolic fraction contained the next highest load of metal. Simil...

Pectinase is used commercially in the clarification and extraction of fruit juice from different fruits. Green apples and Red apples obtained from the fruits section of a supermarket, Idiroko road, Ota were surface sterilized and inoculated with Aspergillus niger. The stock culture was subcultured on Sabouraud Dextrose agar plates and 72-hr-old culture of Aspergillus niger served as the inoculu...

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 ...

Distillery effluent is perilous and hazardous to human race by polluting the water bodies and soil. In whole world every year the total production of distillery products is less then the production of distillery effluents. And due to this the ecological balance continuously disturbing and the food web and food chain of organism also ill effected with the toxic pollutants released from distiller...

Lipase biosynthesis optimization, Aspergillus niger ADM 110, Gamma radiation Objectives: The present study describes the isolation, identification and screening of fugal isolates for the biosynthesis of extracellular lipase enzyme. Methodology: Thirteen fungal cultures were isolated from cotton seeds, waste cake of cotton seed oil and spent bleaching earth, samples by serial dilution method. Al...

Enzymes that are used as animal feed supplements should be able to withstand temperatures of 60 to 90 degrees C, which may be reached during the feed pelleting process. The thermostability properties of three histidine acid phosphatases, Aspergillus fumigatus phytase, Aspergillus niger phytase, and A. niger optimum pH 2.5 acid phosphatase, were investigated by measuring circular dichroism, fluo...

Conserved regions within the M1 family of metallo-aminopeptidases have been used to clone a zinc aminopeptidase from the industrially used fungus Aspergillus niger. The derived amino acid sequence of ApsA is highly similar to two yeast zinc aminopeptidases, LAPI and AAPI (53.3 and 50.9% overall similarity, respectively), two members of the M1 family of metallo-aminopeptidases. The encoding gene...
