چکیده
Sentetik boyaların varlığından kaynaklanan su kirliliği, dünyanın en önemli çevresel sorunlarından biridir. Remazol Brilliant Blue R (RBBR), tekstil endüstrisi atıksularından salınan ve suda ciddi kirliliğe neden olan oldukça toksik boyalardan Bu çalışmada, Pseudomonas putida ile üretilmiş biyojenik mangan oksit (BMO) RBBR’ nin giderimi incelenmiştir. BMO giderimi, çeşitli çözelti pH’ ı, dozajı, başlangıç RBBR konsantrasyonu sıcaklık koşulları altında kesikli modda pH denemeleri optimum ın 3 olduğunu ise adsorpsiyon prosesinin ekzotermik ortaya koymuştur. 30 oC’ de, 3’ te, 0.5 g L-1 dozajında 200 mg konsantrasyonunda 60 dakikalık denge süresi sonunda maksimum kapasitesi 155.7 g-1’ dır. sabit yataklı kolon reaktörde de incelenmiş besleme akış hızının etkisi araştırılmıştır. Elde edilen bulgular, BMO’ in ortamından tehlikeli boyaları uzaklaştırma potansiyeline sahip göstermekte aynı zamanda gelecekteki uygulamaları için bilimsel bir temel sağlamaktadır.

Decolourisation of Remazol Brilliant Blue R via a novel Bjerkandera sp. strain.
A novel strain of Bjerkandera sp. (B33/3), with particularly high decolourisation activities upon Poly R-478 and Remazol Brilliant Blue R (RBBR) dyes, was isolated. The role of the ligninolytic extracellular enzymes produced by this strain on decolourisation of RBBR was studied in some depth. The basis of decolourisation is an enzyme-mediated process, in which the main enzyme responsible is a r...

Efficiency of white-rot fungi-Stereum ostrea (S. ostrea) as a test culture and Phanerochaete chrysosporium (P. chrysosporium) as a reference culture in colour removal from a textile dye, Remazol brilliant blue-19 (RBB-19) in medium was compared in this study. S. ostrea was more efficient than P. chrysosporium in decoloration process. Different parameters pH, temperature, sources of carbon and n...
متن کاملLigninolytic Enzymes Production and Remazol Brilliant Blue R Decolorization by Tropical Brazilian Basidiomycetes Fungi
Remazol Brilliant Blue R (RBBR) dye was used as substrate to evaluate ligninolytic activity in 125 basidiomycetous fungi isolated from tropical ecosystems. The extracellular RBBR decolorizing activity produced when selected fungi were grown in solid media and in soil contaminated with organochlorines was also evaluated. A total of 106 fungi decolorized the RBBR during the growth in malt extract...

decolorization of remazol brilliant blue r (rbbr) by trametessp. pellets was studied in a batch reactor. dye removal process was performed in shaken flasks which contained 100 ml of rbbr aqueous solution and fungal pellets. the process was followed for 48 h and the dye removal was analyzed at a visible spectrum of 590 nm. response surface methodology (rsm) employing box behnken design at three ...
متن کاملDecolourisation Capabilities of Ligninolytic Enzymes Produced by Marasmius cladophyllus UMAS MS8 on Remazol Brilliant Blue R and Other Azo Dyes
Marasmius cladophyllus was examined for its ability to degradatively decolourise the recalcitrant dye Remazol Brilliant Blue R (RBBR) and screened for the production of ligninolytic enzymes using specific substrates. Monitoring dye decolourisation by the decrease in absorbance ratio of A592/A500 shows that the decolourisation of RBBR dye was associated with the dye degradation. Marasmius cladop...
