The present work deals with the ways of testing the compatibility of reactive dyes with cotton in different textile industries in Bangladesh. This report includes three laboratory trials that were carried out for three different reactive dyes to check the compatibility for use in a dye recipe on cotton knitted goods. In this study, Spectrophotometric analysis was conducted and the fixation of e...

The principal phosphoglycoproteins of avian and amphibian egg yolk, known as phosvitins, have been examined extensively in developmental studies of estrogenic induction of protein synthesis (1) and, more recently, as substrates for protein kinases which phosphorylate the basic nuclear proteins (2,3). Phosvitin has few aromatic and basic amino acids (4) which can be detected by uv absorbance or ...

Searching for photoconvertible or photoactivatable dyes, we considered trimethine (Cy3) and pentamethine (Cy5) fluorophores with a 4-amino-1-diazo-2-butanone fragment (H2N(CH2)2COCH=N2) attached to the meso (γ) position of polymethine chain via amino group. The Cy3 derivative was prepared. All Cy5 derivatives basic group at this decomposed breaking chain. However, amino-squaraine based dyes wer...

Abstract. Irawati W, Pinontoan R, Mouretta B, Yuwono T. 2021. The potential of copper-resistant bacteria Acinetobacter sp. strain CN5 in decolorizing dyes. Biodiversitas 23: 680-686. Bacteria with multi-resistance to copper and dyes may be employed bioremediation dye waste more effectively than physical or chemical remediation. This study aims at determining the effect addition various textile ...

textile effluents contain different kinds of chemical dyes and many mutagenic and carcinogenic substances. discharge of these effluents into terrestrial and aquatic ecosystems causes harmful effects. in this research, decolorization of a textile effluent by nineteen different strains of fungi was investigated. removal activity of dyes was in order of   aspergillus > rhizopus > fuzarium > penici...

The first measurements of cytosolic free Ca2", [Ca2"]1, in living cells were made with aequorin in giant muscle cells (Ridgway & Ashley, 1967) in the late 1960s. During the 1970s two further methods were introduced, bis-azo absorbance dyes (mainly arsenazo III) and calciumselective microelectrodes (Ashley & Campbell, 1979). However, even as late as 1981, [Ca'1] had been reliably measured in ver...

I. Introduction Extensive usage of dyestuffs and its disposal are the important sources for the today's environmental contamination. Different types of chemical and physical processes such as chemical coagulation, activated carbon adsorption are used for pollutant removal in the textile industrial wastewater, but they just transfer contaminants from one phase to another that needs further and u...
