Aquatic toxicity of textile dyes and textile and dye industrial effluents were evaluated in an acute toxicity study using Daphnia magna as an aquatic experimental animal model. The 48-h EC50 value for the azo dyes, Remazol Parrot Green was 55.32 mg/L and for Remazol Golden Yellow was 46.84 mg/L. Whereas 48-h EC50 values for three dye industrial effluents (D1, D2, and D3) were 14.12%, 15.52%, and 29.69%, respectively. Similarly, EC50 value for three textile mill effluents (T1, T2, and T3) were >100%, 62.97%, and 63.04%, respectively. These results also showed linear relationship with high degree of confidence ( r2 = >0.84 to >0.99) between immobility and test concentrations. The ratio of 24 to 48-h EC50 remains to be in between 1.1 and 1.2. The general criteria of toxicity classification showed that both dyes were minor acutely toxic having 48-h EC50 in between 10 and 100 mg/L. Of the six textile and dye industrial effluents tested, one was not acutely toxic (48-h EC50 > 100%) and five were minor acutely toxic (48-h EC50 > 14.12–29.69%). The toxicity classification of effluent based on toxic unit (TU) showed that of the six effluents tested five were found toxic (TU = >1) and one was non-toxic (TU = <1). Thus, dye effluents showed highest toxicity and textile effluents lowest toxicity. The study also suggested that the assay with D. magna was an excellent method for evaluation of aquatic toxicity of dyes and dyes containing industrial effluents.

In this study, 23 bacterial strains were isolated from a Cadmium (Cd) contaminated soil in the industrial city, Riyadh of Saudi Arabia. Among these isolates six strains were found to withstand cadmium contamination and grow well. From the six isolates Pseudomonas sp. strain Al-Dhabi-122–127 were found to resist cadmium toxicity to a higher level. The isolates were subjected to biochemical and 16S rDNA gene sequence characterization to confirm their identification. The bacterial strain Al-Dhabi-124 showed 1.5 times higher Cd-degrading activity than Al-Dhabi-122 and Al-Dhabi-123, and Al-Dhabi-126 exhibited 3.5 times higher Cd-degrading activity, higher than the other strains. An atomic absorption spectrophotometer study showed that the strain Al-Dhabi-126 absorbed Cd, and that the bacterial strain Al-Dhabi-126 was found to tolerate cadmium level up to 2100 µg/mL. The bacterial strain Al-Dhabi-126 showed a maximum Cd removal efficacy at pH between 6.0 and 8.0. The efficacy decreased sharply after an increase in pH (9.0). An optimum temperature of 50 °C and pH 6.0 were found to be effective for the Cd removal process by the isolate. The study indicated that the bacterial strain Al-Dhabi-126 can be used effectively for the bioremediation of heavy metals like cadmium, a major toxic pollutant in industrial effluents.

Cyano Compounds

Most cyanide-containing industrial effluents also contain other cyano-derivatives and high amounts of metals and metal-cyanide compounds. For this reason, the biotreatment of these wastes requires the use of microorganisms capable to degrade all these different cyano-compounds and to tolerate metals. Pseudomonas pseudoalcaligenes CECT 5344 is a cyanotrophic bacterium capable of metabolize cyanide in its free form, but it is not very efficient at degrading metal-cyanide complexes. Therefore, for the optimization of the cyanide biodegradation process it is essential to find and characterize new bacterial strains, capable of assimilating metal cyanide-complexes, to complement the capacities of P. pseudoalcaligenes CECT 5344.

AbstractTextile industry releases large quantities of toxic dyes, which is a threat to public health and needs proper management before their release into environment. Out of the different approaches used these days, biodegradation and bio-decolorization is considered an eco-friendly and effective technique as this involves the use of microbes. This technique has the potential to be used effectively for a wide variety of dyes. In biological methods, mainly bacteria, fungi, and some algae are usually employed to remove or decolorize dyes present in textiles effluents and wastewaters. A number of researchers have used bacterial strains and relevant isolated enzymes successfully to decolorize a number of dyes. In this review article, various biological methods that have been used for the biodegradation and decolorization of textile dyes have been described. The review will also revive the significance of biological methods over other physical and chemical treatment methods that would be helpful in ensuring clean environment if used on large scale. Out of these methods, biodegradation through bacterial strains is considered as the best alternative to control water pollution as the growth rate of bacteria is considerably high as compared to other microorganisms. Thus if used the required biomass needed for biodegradation can be obtained in comparatively short interval of time.

High Minimum Inhibitory Concentration

Thirty-one mercury-resistant bacterial strains were isolated from the effluent discharge sites of the SIPCOT industrial area. Among them, only one strain (CASKS5) was selected for further investigation due to its high minimum inhibitory concentration of mercury and low antibiotic susceptibility. In accordance with 16S ribosomal RNA gene sequences, the strain CASKS5 was identified as Vibrio fluvialis. The mercury-removal capacity of V. fluvialis was analyzed at four different concentrations (100, 150, 200, and 250 μg/ml). Efficient bioremediation was observed at a level of 250 μg/ml with the removal of 60% of mercury ions. The interesting outcome of this study was that the strain V. fluvialis had a high bioremediation efficiency but had a low antibiotic resistance. Hence, V. fluvialis could be successfully used as a strain for the ecofriendly removal of mercury.

Decolorization of Sumifix Blue and Reactive Red 2 Textile Dyes by Microbes Isolated from Textile Waste WaterAzo dyes represent the most commonly used group of dyes in textile industry and discharged into industrial effluents worldwide. Aims of this study are to isolate microbe from textile waste water and to determine their ability to decolorize Sumifix Blue and Reactive Red 2 textile dyes. Microbe was isolated from textile effluent of PT Timatex, Salatiga. The activity for decolorization was assayed by inoculating microbial isolates into dye containing medium. Living and nonliving cell were incubated in dye containing medium in order to determine if microbial cells involved in decolorizing dye. Five different microbial isolates have been isolated from textile waste water.  Isolates IBLTT_1 and IBLTT_5 showed the highest activity to decolorize Sumifix Blue, and only isolate IBLTT_1 showed the highest capability in decolorizing Reactive Red 2. Both isolates indicated positive potential towards biotreatment of textile waste water. Further results confirmed that decolorization was due to biodegradation, rather than physical adsorption by inactive cells.Keywords: decolorization, microbial isolation, Reactive Red 2, Sumifix Blue, textile effluent ABSTRAKPewarna azo mewakili kelompok pewarna yang umum digunakan pada industri tekstil dan banyak dijumpai di buangan limbah industri tekstil. Tujuan dari penelitian ini adalah untuk mendapatkan isolat dari limbah tekstil dan untuk mengetahui kemampuannya dalam mendekolorisasi pewarna tekstil Sumifix Blue dan Reactive Red 2. Sampel diperoleh dari limbah industri tekstil PT Timatex, Salatiga. Uji kemampuan dekolorisasi dilakukan dengan menginokulasikan isolat mikroba ke dalam medium Nutrient Broth yang mengandung pewarna. Untuk mengetahui apakah sel mikroba terlibat dalam dekolorisasi pewarna, maka sel hidup dan mati diinokulasi pada medium tersebut. Lima isolat yang berbeda diperoleh dalam penelitian ini. Isolat IBLTT_1 dan IBLTT_5 merupakan isolat dengan kemampuan dekolorisasi Sumifix Blue tertinggi. Isolat IBLTT_1 juga merupakan isolat dengan kemampuan dekolorisasi Reactive Red 2 tertinggi. Kedua isolat tersebut menunjukkan potensi positif terhadap pengolahan limbah tekstil. Hasil lebih lanjut menegaskan bahwa dekolorisasi Sumifix Blue dan Reactive Red 2 disebabkan oleh proses biodegradasi, bukan diadsorpsi oleh sel yang mati.Kata kunci: dekolorisasi, isolat mikroba, limbah tekstil, Reactive Red 2, Sumifix Blue
