“…In agreement with Knasmüller et al (1993) it can be concluded from our results that the mutagenic effects of poorly investigated textile dyes pose a problem. These authors investigated textile samples in situ in the Ames test and found >9% of the samples showing positive results.…”

“…reactive dyes, exposure of consumers is low. But as shown by Knasmüller et al (1993) with the Ames spot test, a relevant proportion of dyes (9.2%) that are active in S. typhimurium is leachable from textile samples. This was confirmed by our own results with the Ames spot test using 92 textile and yarn samples from the TFCs.…”

“…Whereas hazards resulting from these azo dyes, which give rise to carcinogenic amines, are recognized and controlled, this is not the case for textile dyes in general. In a modified Ames test with fabric tested in situ ('Ames spot test'), 9.2% of 196 tested textile samples showed mutagenic effects in Salmonella typhimurium strains TA98 and/or TA100 (Knasmüller et al, 1993). Currently, there are several thousand textile dyes from various chemical classes in use in Europe.…”

In view of compliance with increasingly stringent environmental legislation imposed by regional, national, and supranational (e.g., European Union) authorities, innovative environmental technologies for the treatment of dye-contaminated effluents are necessary in the color industry. In this study, effluents of an industrial dye producer were subjected to distinct treatment trains following an initial qualitative characterization. The effectiveness of ozonation and a treatment using white rot fungi (WRF) and their enzymes were compared with respect to parameters such as residual color, toxicity on human cells, and genotoxicity. A combined ozonation/WRF process was also investigated. The effluent exhibited significant toxicity that was reduced by only 10% through ozonation, whereas the fungal treatment achieved a 35% reduction. A combined treatment (ozone/WRF) caused an abatement of the toxicity by more than 70%. In addition, the initial genotoxicity of the effluent was still present after the ozone treatment, while it was completely removed through the fungal treatment.

“…However, textile dyes make water toxic and unsafe for human and animal consumption. At the same time, they cause an imbalance within the aquatic ecosystem and can serve as mutagenic agents which is harmful to the environment. − Simultaneously, the discharge of effluents pollutes rivers, affecting soil properties as well as the growth of plants along with biodiversity. − …”

A model was designed for effective utilization of textile effluent as the nutrient medium for the production of high-value products from Chlorella variabilis through a greener approach. Biomass productivity of 74.96 ± 2.62 g/(m2/d) with lipid yield of 20.1 ± 2.2% (wrt dry biomass) was obtained using textile effluent as the nutrient source. A novel integrated process is developed based on detergent (sodium dodecyl sulfate) hydrolysis to convert the carbohydrates present in microalgal biomass to reducing sugars for microbial fermentation, while making available lipids for downstream processing of γ-linolenic acid, leaving the protein rich fragment behind. Our experimental data showed that from 495 g of microalgal biomass, 109.4 g total lipids was extracted containing 34.65 g γ-linolenic acid, and 1.3 g pure ε-polylysine from 36.68 g of reducing sugars. A two-step efficient green process was developed for recovering ε-polylysine using ethylammonium nitrate having 74% recovery. In addition to value-added products, CSIR-CSMCRI’s Chlorella variabilis (ATCC PTA 12198) can remediate 100% of aluminum, 82.72% boron, 45.66% calcium, 100% cobalt, 14.5% potassium, 0.1% magnesium, 42.18% sodium, 100% nickel, and 100% iron. A total decrease of 78.17% total phosphate and 25.22% total inorganic phosphate with respect to total phosphate present in the effluent was observed.
