Özet

The bioremoval capacity of Brilliant Blue R (BBR) and Remazol Brilliant Blue R (RBB R) by thermophile Cyanobacterium aponinum was investigated. Trials were carried out at pH 9.5 corresponding to the highest pollutant bioremediation efficiency. C. aponinum removed 97.6% of the applied 9 mg/L BBR; the highest bioremoval was 85.6% in samples with 10.1 mg/L RBB R. Removal capacities of C. aponinum raised with an increase in temperature and inoculum concentration; the highest yield was 70% in RBB R samples with 65.1 mg/L at 35 degrees C. Maximum specific dye removal (q(m)) was 41.1 mg/g in media with 62.7 mg/L BBR at 45 degrees C. There are apparently no other studies investigating dye bioremediation capacity by C. aponinum under different environmental conditions. It can be concluded that removal capacity could be increased by temperature through stimulation of the inoculum production in samples with RBBR. Optimum conditions for the most effective RBB R bioremoval by C. aponinum were pH 9.5, 35 degrees C, and the usage of 20% (v/v) inoculum. The data indicated that C. aponinum is a suitable biosorbent for effective treatment processes of wastewaters, containing dyes.
