and functional groups present in our models, monoazo dye (Tartrazine)
and diazo dye (Ponceau), affects decolorization capabilities of green
algae, cyanobacteria and diatoms. The results revealed that the removal
of azo dyes was rapid at the initial period of study (3 days) and became
slowly with the time (6 days). The maximum decolorization was observed
at 5 ppm Tartrazine with S. bijugatus (68%) and N. muscourm
after 6 days incubation. The reduction of color removal appears to be
related to the molecular structure of the dyes and species of algae used.
The culture of the diatom Nitzschia perminuta was completely died
after 2 days of incubation. Azo reductase of algae, which is responsible
for degradation of azo dyes into aromatic amine by breaking the azo linkage,
was estimated. IR spectra represented a new peak at 3300 cm-1
and a reduction in the azo band at 1642-1631 cm-1. In order
to investigate the sorption behavior of algae, Langmuir equilibrium model
was tested.]]>Allen, M.M.,1968414Aydin, H. and G. Baysal,2006Pistacia khinjuk stocks).]]>196248259Bafana, A., K. Krishnamurthi, S. Devi and T.
