Effect of chemical nutrients on aconitase activity during citric acid fermentation by a mutant strain of Aspergillus niger.
Acta Microbiol Pol. 1998; 47(3):253-60.AM

Abstract

An ethyleneimine and UV irradiated mutant strain Aspergillus niger AB 1801 was explored for its aconitase activity, citric acid production and cell growth during citric acid fermentation. 10% sucrose and 0.25% urea served as the best carbon and nitrogen sources, respectively. Fe2+ stimulated aconitase activity and Co2+ (upto 5 micrograms/mL) and Ni2+ (10 micrograms/mL) strongly depressed enzyme activity. Boric acid (0.5 mg/L) had very good stimulatory response towards citric acid production. Aconitase activity has been found to vary inversely with the citric acid production upto a certain limit after which the activity was absent in the mycelial extract. Cell growth varied with the production parameter.
