Abstract

Abortiporus biennis belongs to a basidiomycete fungi with the unique ability to degrade oxalate using enzyme oxalate oxidase. Oxalate oxidase (OXO) from Abortiporus biennis is an intracellular oxalic acid-induced enzyme, which catalyses the degradation of oxalic acid to carbon dioxide and hydrogen peroxide. OXO activity was stimulated by all the heavy metals tested (copper, manganese, lead and cadmium) after addition as water-soluble salts to A. biennis fungal cultures. Manganese ions stimulated OXO activity to the greatest extent among the tested metal ions. In the presence of manganese ions, an elevated concentration of oxalate was also detected in the fungal culture after 7 days of cultivation. The manganese, lead, and cadmium ions were accumulated by the A. biennis mycelium. Among them, lead was accumulated to a great extent. It was observed that the accumulation of lead ions occurred in the vicinity of the A. biennis hyphal cell wall.

期刊介绍： BioMetals is the only established journal to feature the important role of metal ions in chemistry, biology, biochemistry, environmental science, and medicine. BioMetals is an international, multidisciplinary journal singularly devoted to the rapid publication of the fundamental advances of both basic and applied research in this field. BioMetals offers a forum for innovative research and clinical results on the structure and function of: - metal ions - metal chelates, - siderophores, - metal-containing proteins - biominerals in all biosystems. - BioMetals rapidly publishes original articles and reviews. BioMetals is a journal for metals researchers who practice in medicine, biochemistry, pharmacology, toxicology, microbiology, cell biology, chemistry, and plant physiology who are based academic, industrial and government laboratories.
