“…The optimization of conditions for enhanced decolorization of dye RB 172 was carried out by one parameter approach at a time. Initially, the effect of microaerophilic and aerobic incubation (shaking at 120 rpm), preenriched culture medium pH (3)(4)(5)(6)(7)(8)(9)(10)(11)(12), incubation temperature (20,30,37,40, and 50 ± 0.2 ∘ C), and dye concentrations (50-250 mg L −1 ) was evaluated. At defined time of intervals the aliquots of culture supernatant (3 mL) were withdrawn and suspended particles were removed by adding equal volume of methanol followed by centrifugation (7500 ×g for 15 min, 4 ± 0.2 ∘ C) [13].…”

Present study focuses on exploitation of agricultural waste wheat bran (WB) as growth medium for degradation of textile azo dye C.I. Reactive Blue 172 (RB 172) using a single bacterium P. rettgeri strain HSL1 (GenBank accession number JX853768.1). The bacterium was found to completely decolorize 50 mg L −1 of dye RB 172 within 20 h at 30 ± 0.2 ∘ C under microaerophilic incubation conditions. Additionally, significant reduction in COD (85%) and TOC (52%) contents of dye decolorized medium was observed which suggested its mineralization. Induction in the activities of azoreductase (159%) and NADH-DCIP reductase (88%) provided an evidence for reductive cleavage of dye RB 172. The HPLC, FTIR, and GC-MS analysis of decolorized products confirmed the degradation of dye into various metabolites. The proposed metabolic pathway for biodegradation of RB 172 has been elucidated which showed the formation of 2 intermediate metabolites, namely, 4-(ethenylsulfonyl) aniline and 1-amino-1-(4-aminophenyl) propan-2-one. The acute and phytotoxicity evaluation of degraded metabolites suggests that bacterial strain favors the detoxification of dye RB 172. Thus, WB could be utilized as a low-cost growth medium for the enrichment of bacteria and their further use for biodegradation of azo dyes and its derivatives containing wastes into nontoxic form.

“…Polluted sites often contain a mixture of heavy metals and toxic xenobiotics. The search for multiple detoxification microorganisms is on the rise globally (Ahmad et al 2013b;Agrawal et al 2014;Ahmad et al 2014;Muhamad et al 2015). Examples include the heavy metal chromate reduction coupled to azo dye decolourization (Chaudhari et al 2013) and the isolation of Mo-reducing bacteria showing sodium dodecyl sulfate (SDS)-degrading Masdor et al 2015), phenol-degrading (Ibrahim et al 2015) and glyphosatedegrading (Sabullah et al 2016) properties.…”

Abstrak: Satu bakteria penurun molibdenum dengan keupayaan baru untuk menyahwarna pewarna azo Kuning Metanil dilaporkan. Kondisi optimum untuk penurunan molibdenum adalah pada pH 6.3 dan pada suhu 34°C. Glukosa adalah penderma elektron yang terbaik. Keperluan-keperluan lain termasuklah kepekatan fosfat yang sempit di antara 2.5 dan 7.5 mM. Profil masa pengeluaran Mo-biru menunjukkan tempoh sela masa kira-kira 12 jam, jumlah maksimum Mo-biru dihasilkan pada kepekatan molibdat 20 mM dan pengeluaran maksimum pada masa 52 jam inkubasi. Logam-logam berat seperti merkuri, perak, tembaga dan kromium merencat penurunan sebanyak 91.9, 82.7, 45.5 dan 17.4%, masing-masing. Penyahwarnaan pewarna Kuning Metanil pada kepekatan 100 dan 150 mg/L berlaku pada hari ketiga dan hari enam inkubasi, masing-masing. Kepekatan yang lebih tinggi menghasilkan degradasi separa, dengan penyahwarnaan warna sebanyak 20% berlaku pada kepekatan 400 mg/L. Bakteria ini dikenal pasti secara separa berdasarkan analisis biokimia sebagai Bacillus sp. strain Neni-10. Spektrum penyerapan Mo-biru mencadangkan bahawa kompaun terhasil adalah fosfomolibdat terturun. Pengasingan bakteria ini, yang menunjukkan penurunan logam berat dan keupayaan penyahwarnaan pewarna, adalah diperlukan, terutamanya untuk bioremediasi.Kata kunci: Penurun Molibdenum, Molibdenum Biru, Bacillus sp., Pewarna Azo, Kuning Metanil Abstract: A molybdenum reducing bacterium with the novel ability to decolorise the azo dye Metanil Yellow is reported. Optimal conditions for molybdenum reduction were pH 6.3 and at 34°C. Glucose was the best electron donor. Another requirement includes a narrow phosphate concentration between 2.5 and 7.5 mM. A time profile of Mo-blue production shows a lag period of approximately 12 hours, a maximum amount of Mo-blue produced at a molybdate concentration of 20 mM, and a peak production at 52 h of incubation. The heavy metals mercury, silver, copper and chromium inhibited reduction by 91.9, 82.7, 45.5 and 17.4%, respectively. A complete decolourisation of the dye Metanil Yellow at 100 and * Corresponding author: yunus.upm@gmail.com Rusnam Mansor et al. 70150 mg/L occurred at day three and day six of incubations, respectively. Higher concentrations show partial degradation, with an approximately 20% decolourisation observed at 400 mg/L. The bacterium is partially identified based on biochemical analysis as Bacillus sp. strain Neni-10. The absorption spectrum of the Mo-blue suggested the compound is a reduced phosphomolybdate. The isolation of this bacterium, which shows heavy metal reduction and dye-decolorising ability, is sought after, particularly for bioremediation.

“…Concentration of 4-nitroaniline was 100 µmol L -1 Garg et al, 2012;Agrawal et al, 2013). Microbial degradation provides most promising possibility for complete mineralization of dyes and intermediates (aromatic amines), due to greater adaptability and increased rate of bacterial growth (Saratale et al, 2011;Singh et al, 2015).…”

Wastewater from textile processing and dyestuff manufacturing industries contains different kinds of dyes and their metabolites, which are mutagenic and carcinogenic in nature. Such wastewater should be treated in order to avoid ground and surface water contamination. The aim of present research was to isolate such bacterial strains which are capable of degrading dye-originated aromatic amines. Ten samples of wastewater and sludge were collected from outlets and wastewater streams of different textile industries. The analysis of wastewater showed a wide variation in the pH (8.10-12.3), total dissolved solids (500-20100 mg L ) using 10 mL wastewater/sludge as inoculum source. Based on ability to degrade 4-nitroaniline most efficient bacterial strain was identified as Raoultella planticola (IL11) through 16S rRNA gene analysis. These findings suggest that the indigenous bacterial strains have potential for bioremediation of dye-containing textile effluents, and for complete mineralization, 4-nitroaniline degrading strains may be used in combination with dye degrading strains.
