Abstract [en]

The decolourization of a mixture of 200 mg/l each of Reactive Black 5 and Reactive REd 2 dye was studied in batch experiments using microorganisms growing on forest residue wood chips in combination with or without added white-rot fungus, Bjerakndera sp. BOL 13. The study was performed as a first stage in the development of a relatively simple treatement process for textile wastewater, designed to work in developing countries. Forest residue wood chips contain a mixture of fungi and bacteria which is an advantage when complex molecules should be degraded. The wood chips furthermore provide the microorganisms with carbon source which make the addition of e.g. glucose unnecessary. The results showed that the microorganisms growing on the forest residue wood chips decolourized the mixture of the two dyes; adding extra nutrients approximately doubled the decolourization rate. The time needed for decolourization was approximately 18 days when nutrients were added. Lignocellulosic material is complex and so were the analysis, microorganisms were therfore transferred to ordinary soft wood chips from forest residue wood chips, Decolourization was measured with spectrophotometer an in order to determine intermediates HPLC was used.
