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...

Biodiversity of phylloplane and endophytic fungi have been considered as one of the rich source of novel natural compounds of biological activities and a high level of structure diversity on the leaf surfaces. Bioactive components produced by phylloplane and endophytes have shown promising potentiality towards human health. In this juncture, it is necessary to understand and manipulate this imp...

A combination of MICs of an N-chloramine, a simple chlorinated amino acid, and diazolidinyl urea gave synergistic activity against bacteria, but not fungi. The two compounds at a higher concentration, 0.1 and 0.3%, respectively, gave synergistic inhibition of fungi; kill times were 1 h for Trichophyton tonsurans, 3 h for Aspergillus niger and Fusarium moniliforme, and 6 h for Aspergillus fumiga...

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...

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...

Fungi combine the advantages of a microbial system such as a simple fermentability with the capability of secreting proteins that are modified according to a general eukaryotic scheme. Filamentous fungi such as Aspergillus niger efficiently secrete genuine proteins but the secretion of recombinant proteins turned out be a difficult task. Aspergillus niger is an attractive organism because of it...

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...

Bacteria are able to synthesis a wide range of metabolites with fungicidal capabilities. The antagonistic potential of soil bacterial strains (E. coli, Baccillus fortis, B. faragiris, Pseudomonas flourescence and P. malophilia) was assessed by the dual culture technique against some food pathogenic fungi, i.e. Aspergillus flavus, A. niger, Penicillium italicum and P. simplicissmum. The result i...

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...
