Abstract :In the current study, bioremediation of Cuinsert ignore into journalissuearticles values(II); by thermophile Cyanobacterium aponinum has been studied in BG11 media under different conditions. The optimum pH was 9 due to the maximum Cuinsert ignore into journalissuearticles values(II); bioremoval efficiency as 71% in the medium with12.8 mg/L Cuinsert ignore into journalissuearticles values(II);. According to the results obtained from the trials, the highest bioremoval was 76.6% in the medium including 9.7 mg/L Cuinsert ignore into journalissuearticles values(II); for incubation period of 10 days. When the effect of increasing temperature insert ignore into journalissuearticles values(25-45 °C); and biomass [20% and 40% insert ignore into journalissuearticles values(v/v);] concentrations on bioremediation by C. aponinum was investigated, the highest heavy metal removal was found 75.8% at 45 °C, 12.8 mg/L Cuinsert ignore into journalissuearticles values(II);, and 20% insert ignore into journalissuearticles values(v/v); biomass concentration. It was 76.3% in the medium with 13.8 mg/L pollutant, 40% insert ignore into journalissuearticles values(v/v); biomass concentration. The qm insert ignore into journalissuearticles values(maximum specific Cuinsert ignore into journalissuearticles values(II); removal); was found as 6.1 mg/g at 45 °C in BG11 with 40% insert ignore into journalissuearticles values(v/v); biomass and 13.8 mg/L Cuinsert ignore into journalissuearticles values(II);. It has been concluded that Cuinsert ignore into journalissuearticles values(II); bioremediation by thermophile C. aponinum was firstly investigated at various environmental conditions in this study. The results indicated that the tested cyanobacterium had a great potential to remove heavy metals from the aquatic environments, containing Cuinsert ignore into journalissuearticles values(II);.
