Abstract We investigated the dye-removal potential of a collection 61 cold-adapted yeasts from King George Island, Antarctica, on agar plates supplemented with 100 mg L –1 several textile dyes; among which isolates 81% decolorized Reactive Black 5 (RB-5), 56% decolorizing Orange 16, but only 26% doing so Blue 19 and Acid 74. Furthermore, we evaluated ligninolytic using 2,2ʹ-azino-bis(3-ethylben...

Abstract The removal of reactive blue 49 dye on a bio-sorbent material for Natural lemon peels(NLP) and Acid-activated carbon peels(AACLP) from aqueous solutions was studied. Preparation activated by Calcinations at temperature (300°C) one hour chemical activation phosphoric acid. Study different parameter such as effect contact time, adsorbent dose, pH solution, solution Adsorption comparison ...

One kind of adsorbent with a high adsorption capacity for anionic dyes was prepared using ionically and chemically cross-linked chitosan beads. A batch system was applied to study the adsorption behavior of one acid dye (MY, metanil yellow) and one reactive dye (RB15, reactive blue 15) in aqueous solutions by the cross-linked chitosan beads. The adsorption capacities was 3.56 mmol g(-1) (1334 m...

PURPOSE The importance of gamma probe detection (GPD) combined with vital dye for sentinel node (SN) biopsy is well accepted. We evaluated the efficacy of patent blue dye (PBD) in identifying inguinal SN. METHODS Ninety-four cutaneous melanoma patients with inferior extremity lesions were submitted to SNB according to a established protocol. Patients were randomized in two groups: Blue group,...

PURPOSE This study investigated whether a nonradioactive dye, Evans blue, can be adapted as a safe alternative to the isotope-dilution method for quantitating blood-retinal barrier breakdown. METHODS Blood-retinal barrier breakdown was induced in rats with vascular endothelial growth factor (VEGF) or through the induction of diabetes. After allowing Evans blue to circulate in the vasculature,...

background: the presence of even a very small quantity of dye in water bodies is undesirable and affects the water bodies. dye removal from industrial waste water is significant; hence in this study, a material that is an economical waste product was employed to test its acid dye removing capacity from aqueous solution. methods: in this study, batch mode experiments were performed in the sorpti...

IT is a fact well known to histologists that certain basic dyes undergo a change of tint when taken up by particular tissue elements, especially cartilage, mucus and the granules of the so-called 'mast cells'. The chemistry of this phenomenon, named 'metachromasia' by Ehrlich, has been studied in some detail by Lison [1935], This investigator concluded that the change of colour in the dye is du...
