Production of Kojic Acid by Aspergillus effusus Tiraboschi

Production of aflatoxins and kojic acid by species of Aspergillus and Penicillium.

Aspergillus oryzae-based cell factory for direct kojic acid production from cellulose

BACKGROUND Kojic acid (5-Hydroxy-2-(hydroxymethyl)-4-pyrone) is one of the major secondary metabolites in Aspergillus oryzae. It is widely used in food, pharmaceuticals, and cosmetics. The production cost, however, is too high for its use in many applications. Thus, an efficient and cost-effective kojic acid production process would be valuable. However, little is known about the complete set o...

Kojic Acid Production from Agro-Industrial By-Products Using Fungi

A total of 278 different isolates of filamentous fungi were screened using synthetic medium for respective ability to produce kojic acid. Nineteen, six, and five isolates proved to be low, moderate, and high kojic acid producers, respectively. Levels of kojic acid produced were generally increased when shaking cultivation was used rather than those obtained using static cultivation. A trial for...

Oxalic Acid Production by Aspergillus Niger

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...

Toxicity and Antibiotic Activity of Kojic Acid Produced by Aspergillus luteo-virescens.

In a systematic investigation for new antibiotics it was observed by one of us (A. K.) that the crude culture filtrate of Aspergillus luteo-virescens was found to be antagonistic to gram-positive and gram-negative bacteria. In the chemical studies conducted by two of us (W. K., R. K.) it was noted that an antibiotic substance crystallized out in large amounts from this crude culture upon standi...
