dc.description.abstract | This study aims to investigate an advanced biological processes these are relayed to biodegradable
potential of growing microbial cells for contaminated water treatment. Thus the use of the
Streptomyces fulvissimus CKS 7 has been evaluated for decolorizing efficiency of a solution
containing a cationic triphenylmethane dye, crystal violet (CV). The color reduction was
monitored by UV–Vis spectroscopic analysis, through changes in their absorption spectrum and
comparing the results, to those of the respective controls. It was found that the CKS 7 performed
well and reached up to 100 % of effectiveness. The required process parameters have been
apparently mild and include the 10 % inoculum size, reaction temperature of 27-30° C, under
shaking conditions, whereas the time course of decolorization has been concentration dependent.
A possible mechanism for removing dye from working medium was accomplished in two steps:
binding of the dye by bacterial cells on their surface in addition to dye biodegradation by bacterial
intracellular enzymes. After one cycle of the complete dye removal, adapted culture was
successfully reused for the same purpose. The phytotoxicity analysis revealed that no toxic
compounds were present in decolorized medium, indicating that the use of CKS 7 bacteria seems
to be promising applicants for contaminated water treatment. | sr |
