Heavy metals biomineralization by some
Cyanobacterial isolates
|
|
| Abstract |
Three cyanobacterial isolates (Spirulina platensis, Nostoc muscorum, and Anabaena oryzae) were used individually or as a mixed culture to precipitate some heavy metals (Hg2+, Cd2+, Cu2+ and Pb2+) out of their solutions through using the culture biogas produced during their aerobic growth in a batch bioreactor. Variable capabilities of metal bioprecipitation were recorded by the three algal isolates. FT-IR studies showed the existence of –OH groups in the metal precipitate
produced by the algal isolates while –NH groups were identified only in the metal precipitates produced by N. muscorum, and A. oryzae. In conclusion, this study highlighted a novel approach for heavy metals bioremediation through the transformation of these metals into nitrogen complexes and/or hydroxide complexes via using the culture biogas produced by some cyanobacterial species
