Introduction Sambucus nigra, or European elder, is a tall tree-like shrub, native to Europe, Asia, and North Africa, and naturalized in the United States. Various parts of the elder have long been used in traditional medicine as a diaphoretic, diuretic, astringent, laxative, and emetic. The berries were used traditionally as a food to make elderberry wine and pies, and as a flavoring or dye. Cu...

Solid-state fermentation (SSF) is envisioned as a prominent bio conversion technique to transform natural raw materials into a wide variety of chemical as well as biochemical products. SSF is being successfully exploited for food production, fuels, enzymes, antibiotics, animal feeds and also for dye degradation. The reuse of agro-industrial wastes in SSF processes is of particular interest due ...

we demonstrate that photothermal deflection spectroscopy can be used to measure velocity distributions in dye jets. such measurements are useful in determining the quality of flow in dye jets, the quality of jets is very important for a stable and naanow linewidth operation of dye lasers

in the present study, hydrilla verticillata biomass was investigated as a novel biosorbent for the uptake of basic dye malachite green from its aqueous solution. kinetic and equilibrium studies were carried out in batch process. batch adsorption experiments were conducted to study the effect of ph, temperature, sorbent dosage, initial dye concentration, and contact time for the removal malachit...

C-Phycocyanin is a natural blue dye used in food and pharmaceutical industry. In the present study, a simple and efficient method to extract C-phycocyanin from Spirulina platensis wet biomass is reported. The extractions were carried out using six different methods, including chemical (organic and inorganic acid treatment), physical (freezing and thawing, sonication, homogenization) and enzymat...

The Aravalli ranges run along the Sabarkantha district is the ancient region of India, inhibited by tribals living in close vicinity of enriched forest. The present paper contains various ethnobotanical aspects of some plant species used by the tribals for their day-to day requirement. The paper includes the first hand information collected through tribal informants, medicinemen and tribal peop...

Different azo dyes are widely used in textile, printing, cosmetic, drug and food processing industries. Metanil Yellow, a monosodium salt of 3-[[4-(Phenylamino) phenyl] azo] benzenesulfonic acid is one among those. It is a non-permitted food colour as well as an additive. Azo dyes are also used in laboratories as biological indicators or as pH indicators. There are varieties of food additives, ...

nanocrystalline titanium (iv) oxide paste has been deposited on fluorine doped tin oxide glass substrate by the blade method. the deposited film was subjected to thermal treatment to obtain an electrode foe a photo-electrochemical cell. the electrode was sensitized with prophyrin dye which was a local dye extracted from carica papaya leaves. avaspec 2.1 spectrophotometer was used to obtain the ...

ZnO and TiO2 nanoparticles wereimpregnated with merbromin dye and used as modified photocatalysts for degradation of phenol. Dye-modified ZnO and TiO2 showed significantly higher photocatalytic activity than neat ZnO and TiO2 under visible light illumination. Moreover, the prepared dye-modified ZnO showed superior photocatalytic efficiency in degrad...
