[Genotoxicity of synthetic dyes in umu test using Salmonella typhimurium TA1535/pSK1002 (1). Results of examination for acid dyes, direct dyes, disperse dyes and reactive dyes].
The umu test system is a newly developed method to evaluate genotoxicities of a wide variety of environmental carcinogens and mutagens (Oda et al., 1985; Nakamura et al., 1987). In the present study, SOS-inducing activity of 142 synthetic dyes was investigated by the umu test using Salmonella typhimurium (TA1535/pSK1002) under the condition of absence and presence of rat liver microsomal fracti...
متن کاملAdsorption of Acid Dyes on Modified Mesoporous SBA-15: Comparison of Two Dyes
In this study, SBA-15-PAMAM mesoporous Nano-adsorbent was synthesized, characterized and applied for adsorption of Acid dyes (Acid Blue 62 (AB62) and Acid Red 266 (AR266)) from aqueous Medias. Adsorption of AB62 and AR266 on SBA-15 ordered mesoporous silica, polyamidoamine functionalized SBA-15(SBA-15-PAMAM), has been investigated. In order to assess the synthesized adsorbent constructional, FT...
متن کاملModification of azo dyes by lactic acid bacteria.
AIM The ability of Lactobacillus casei and Lactobacillus paracasei to modify the azo dye, tartrazine, was recently documented as the result of the investigation on red coloured spoilage in acidified cucumbers. Fourteen other lactic acid bacteria (LAB) were screened for their capability to modify the food colouring tartrazine and other azo dyes of relevance for the textile industry. METHODS AN...
متن کاملRemoval of Anionic Dyes (Direct Blue 106 and Acid Green 25) from Aqueous Solutions Using Oxidized Multi-Walled Carbon Nanotubes
Background and purpose:The presence of dyes in wastewaters may cause serious problems for the environment because of their high toxicity to aquatic organisms and unfavorable aesthetical impact. In the present study, multi-walled carbon nanotubes (MWCNTs) were used for removal of anionic dyes Direct Blue 106 (DB106) and Acid Green 25 (AG25), from water samples. Materials and Methods:MWCNTs were ...
متن کاملBacteriostasis by Mixture of Dyes
It is possible to mix two dyes of opposite selective bacteriostatic powers and obtain a mixture which combines the powers of the two components. This possibility has been established by experiments with a mixture of gentian violet, which has a predilection for Gram-positive organisms, and acriflavine, which has a predilection for Gram-negatives; a mixture of these two dyes is quite bactericidal...
