Box 56, Biocenter 1, FI 00014 University of Helsinki, Finland Email: [email protected] Abstract: To find out ability of fourteen basidiomycetes and four ascomycetes strains to grow in the presence of synthetic colour dyes and to degrade them, fungi were ...

Background & objectives: Dyes are structurally complex materials, which enter into the environment due to discharging of textiles effluent from dyeing and printing processes. Reactive Blue 52 dye is used widely in the textile industry. Therefore, we investigated the efficiency of the filamentous Alga as natural adsorbent in the removal of Reactive Blue 52 dye from textile wastewater. Methods: ...

The objective of this work is investigation of the adsorption and decomposition of Reactive Blue 19 from industrial wastewaters using laccase enzyme immobilized on activated carbon powder and fiber as adsorbent. Time, pH, temperature, stirring rate, the amount of the adsorbent, dye initial concentration, solution flow rate in the column and column height were studied as key operating parame...

The ability of a particular banana fibre in removing reactive dyes from textile wastewater was studied in the present work. Locally available ground seeded banana fibre of ≤ 212 μ was used as adsorbent. Initially the adsorbent was tested on standard Novacron Blue FN-R reactive dye solutions and then it was also applied to raw textile wastewater. The adsorbent was found very effective to remove ...

A cellulose biopolymer was doped with Fe and Al forming a mesoporous composite. The composite showed excellent adsorption capacities of 117.86 mg g −1 95.62 for Reactive red 21 blue 19 respectively.

White rot fungus Marasmius sp. BBKAV79 (GenBank accession number-KP455496, KP455497) exhibited decolourization and degradation of Navy blue HER dye (concentration 50 mg l-l) within 24 h under shaking condition. In the present study, various investigated parameters like initial dye concentration, pH, temperature, carbon and nitrogen sources were optimized to develop a faster decolourization proc...

Ten phenols were selected as natural laccase mediators after screening 44 different compounds with a recalcitrant dye (Reactive Black 5) as a substrate. Their performances were evaluated at different mediator/dye ratios and incubation times (up to 6 h) by the use of Pycnoporus cinnabarinus and Trametes villosa laccases and were compared with those of eight known synthetic mediators (including -...

Antimicrobial photodynamic inactivation (APDI) using phenothiazinium dyes is mediated by reactive oxygen species consisting of a combination of singlet oxygen (quenched by azide), hydroxyl radicals and other reactive oxygen species. We recently showed that addition of sodium azide paradoxically potentiated APDI of Gram-positive and Gram-negative bacteria using methylene blue as the photosensiti...

Our eyes are increasingly exposed to light from the emitting diode (LED) light of video display terminals (VDT) which contain much blue light. VDTs are equipped with televisions, personal computers, and smart phones. The present study aims to clarify the mechanism underlying blue LED light-induced photoreceptor cell damage. Murine cone photoreceptor-derived cells (661 W) were exposed to blue, w...
