  • Title: Butyltins degradation by Cunninghamella elegans and Cochliobolus lunatus co-culture.
    Author: Bernat P, Szewczyk R, Krupiński M, Długoński J.
    Journal: J Hazard Mater; 2013 Feb 15; 246-247():277-82. PubMed ID: 23314396.
    Abstract:
    Organotin compounds are ubiquitous in environment. However, biodegradation of tributyltin (TBT) and dibutyltin (DBT) to non toxic metabolites by fungi has been seldom observed. In this study we constructed a fungal co-culture with an efficient ability of TBT and its metabolites removal. The microscopic fungus strain Cunninghamella elegans degraded TBT via hydroxybutyldibutyltin (OHBuDBT) to its metabolites: DBT and monobutyltin (MBT), which were then transformed by Cochliobolus lunatus. The sequential biodegradation resulted in a 10-fold decrease in samples toxicity to Artemia franciscana larvae. With an initial TBT concentration of 5 mg l(-1), the co-culture of both fungi almost completely eliminated butyltins during 12 days of incubation in synthetic medium. To our knowledge, this is the first report that the mixed fungal co-culture could efficiently degrade TBT. This process was associated with glucose utilization, and a cometabolic nature of butyltins removal by selected strains has been suggested.
