Applicant's summary and conclusion
- Conclusions:
- The aim of this paper was to quantify bioaccu mulation and subsequent biovolatilization of As(III), As (V), Se(IV), Se(VI), Sb(III), Sb(V), Te(IV), Te(VI), Hg (II), Tl(I) and Bi(III) by microscopic filamentous fungus Scopulariopsis brevicaulis under laboratory conditions. The filamentous S. brevicaulis fungus is a known methylator of arsenic and antimony, which indicated possible ability of methylating and volatilizing of other metals and metalloids. The S. brevicaulis 1524 strain was capable of accumulating and volatilizing all used chemical elements in all valence states under laboratory conditions when single-metal(loid) solutions were used. S. brevicaulis fungus was found to be the most suitable for Se(IV), Te(IV), Hg(II) and Bi(III) removal. The rate and amount of biovolatilized Te in the filamentous fungus Scopulariopsis brevicaulis also appeared to be concentration-dependent, which suggest that this organism actively tried to regulate the internal concentration levels.
- Executive summary:
Biovolatilization and bioaccumulation capabilities of different elements by microscopic filamentous fungus Scopulariopsis brevicaulis were observed. Accumulation of As(III), As(V), Se(IV), Se(VI), Sb(III), Sb(V), Te(IV), Te(VI), Hg(II), Tl(I) and Bi(III) by S. brevicaulis was quantified by analysing the amount of elements in biomass of the fungus using ICP AAS. The highest amounts of bioaccumulated metal(loid)s were obtained as follows: Bi(III) > Te (IV) > Hg(II) > Se(IV) > Te(VI) > Sb(III) at different initial contents, with Bi (III) accumulation approximately 87%. The highest percentages of volatilization were found using Hg(II) (50%) and Se(IV) (465%); it was also demonstrated with all studied elements. This proved the biovolatilization ability of microscopic fungi under aerobic conditions. The highest removed amount was observed using Hg(II) (95-30%), and more than 80% of Se(IV), Te(IV), Bi(III) and Hg(II) was removed by bioaccumulation and biovolatilization, which implies the possibilities of use of these processes for bioremediations. There were reported significant differences between bioaccumulation and biovolatilization of almost all applied metal(loid)s if valence is mentioned.
