This study investigates the optimal conditions for preparation of corn cob based activated carbon (CCAC) for the removal of Remazol Brilliant Blue R (RBBR) reactive dye from aqueous solution. The CCAC was prepared by using physiochemical activation method which consisted of sodium carbonate (Na2CO3) and CO2 gasification. Central composite design (CCD) was used to determine the effects of the th...

The application of synthetic dyes in various industries improved the aesthetic properties of the products, but the discharge of dye-containing effluent into water bodies leads to serious environmental problems. Till date, colour removal from effluent is still a challenge due to the absence of economically attractive treatments. In this study, decolourization of a synthetic dye – Remazol brillia...

Pycnoporus sanguineus is a white-rot basidiomycete that produces laccase as the only oxidoreductase; enzyme synthesis depends on cultivation variables, and fungal species and strain. Laccases have wide substrate specificity, oxidize a broad range of compounds, and show potential for use in dye decolorization. We evaluated laccase production in a recently isolated strain of P. sanguineus cultiva...

TiO2 and doped Cd, Co, Mn (TiO2-M) were synthesized with a sol-gel method, the photocatalytic activity of Remazol Brilliant Blue R Yellow FG has been conducted. TiO2-M (Cd, Mn) was mol Ti:M ratio 3:1, materials calcined at 300, 400, 500 °C. The characterized by X-ray Diffraction (XRD), Scanning Electron Microscopy-Energy Dispersive (SEM-EDX), UV-Vis Reflectance. XRD result shows that temperatur...

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...

Over the past few decades, enzyme-based green and sustainable chemistry has attracted extensive research attention, which provides a promising alternative to conventional treatment methods of recalcitrant micropollutants. However, enzyme denaturation stability loss remain critical challenges for its potential applications in industrial wastewater treatment. In this study, laccase from Trametes ...

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...

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...

Response surface methodology (central composite design of experiments) was employed to simultaneously optimize enzyme production and productivities of two ligninolytic enzymes produced by Ceriporiopsis subvermispora. Concentrations of glucose, ammonium tartrate and Polysorbate 80 were varied to establish the optimal composition of liquid media (OLM), where the highest experimentally obtained ac...
