In the present study, different approaches are being compared for the decolorization of reactive orange 4 monoazo dye by Bacillus cereus isolate under varied cultural and nutritional conditions. By employing conventional one-factor-at-a-time approach, the bacterial strain exhibited decolorization activity over a wide range of pH (7.0-9.0), temperature (30-38°C), dye concentration (50-200 mg LG 1 MSM) and inoculum size (1.0-6.0%, v/v), with peak activity (68.2% color removal) at pH 8.0, 35°C, 50 mg dye LG 1 MSM and 4.0% (v/v) inoculum in the presence of 1.0% (w/v) glucose as carbon/energy source and 0.2% (w/v) ammonium nitrate within 72 h incubation. Under response surface methodology (RSM using Box-Behnken design) approach, the dye decolorization enhanced to 100% at optimized 40 mg reactive orange LG 1 MSM, glucose 1.0% (w/v) and ammonium nitrate 0.2% (w/v) during 72 h of incubation. The dye decolorization time was advanced by 12 h in bioreactor trial and 100% color removal was achieved within only 60 h incubation. In future experimentation, we envisage to test the potential of our isolate for the decolorization of other variety of azo dyes, mixture of dyes as well as the real textile effluent.

BACKGROUND: Anaerobic technology is one of the most highly efficient methods for the biological treatment of dye wastewater by means of the reductive cleavage of the azo linkages. Dissimilatory Fe(III)-reducing microorganisms play crucial roles in a number of processes of environmental concern. The main objective of the study was to investigate the novel Fe(III)-reducing strain isolated from a BES enhanced by addition of Fe(OH) 3 . RESULTS:In this study, a new electrogen, Sphingomonas strain DJ, was isolated from a microbial electrochemical reactor with Fe(OH) 3 added. The iron-reduction and the dye decolorization efficiencies of this strain achieved 69.04% and 97.65%, respectively. Cyclic voltammetry showed that strain DJ had electrochemical activity. The dye concentration, operating temperature and pH had obvious effects on the performance of the strain. Addition of Fe(III) into the medium further enhanced the decolorization efficiency. The possible pathway of the reduction of AO7 with the new strain was proposed. CONCLUSION: The model developed for this study could provide a new method for enriching electroactively Fe(III)-reducing bacteria to treat other refractory wastewaters. Figure 2.

“…In Indonesia, aside from heavy metals, the organic pollutant azo dyes are often present as co-pollutants in water and soils and in wastewater treatment plants (Meitiniarti et al 2007). Basic and diazo direct dyes are being produced on the order of nearly one million tons yearly.…”

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.
