The effects of inorganic salts on biosynthesis of pectinolytic enzymes by Aspergillus Niger

The paper examines effects of different inorganic salts in an apple pulp base on the production of pectinolytic enzymes with the aim of optimizing the medium for maximal enzyme production. The apple pulp combined with corn flour and simple mineral salts was used as a nourishing base in submerged production of pectinolytic enzymes by the fungus Aspergillus niger MK-15. The growth of the microorganism (dry weight) on different sources of nitrogen showed maximum dry weight with (NH4)2HPO4. The growth of the microorganism (dry weight) on different concentration of (NH4)2HPO4 (by 0.2% to 0.8%) provided maximal dry weight with 0.7% (NH4)2HPO4. The different inorganic salts (sources of nitrogen) on base stimulated the production of pectinolytic enzymes and enhanced by up to twofold the growth of Aspergillus niger in submerged fermentation. The best source of nitrogen on base was (NH4)2HPO4 with optimal concentration of 0.7%. The obtained results represent practical importance for using apple pulp as a carbon source for production of pectinolytic enzymes in submerged fermentation.

Ancient Greece, its history, philosophy and literature, that has been my love since childhood. Although my profession is only marginally related to all this - I work as a revision technician in a certain undisclosed company. In addition, I recreationally train in martial arts and prepare for a marathon. This blog is an opportunity for me to share with you everything that no longer fits into other boxes of my life.
