Abstract. Irawati W, Pinontoan R, Mouretta B, Yuwono T. 2021. The potential of copper-resistant bacteria Acinetobacter sp. strain CN5 in decolorizing dyes. Biodiversitas 23: 680-686. Bacteria with multi-resistance to copper and dyes may be employed bioremediation dye waste more effectively than physical or chemical remediation. This study aims at determining the effect addition various textile ...

Recently, the research on remediation of aqueous organic pollutants over visible-light-active photocatalysts has got much attention. Therefore, this study reports fabrication Co3O4-Bi2O3 heterojunction photocatalyst for photodegradation rhodamine B dye. The was synthesized by coprecipitation method and characterized XRD, EDS, SEM, TEM, TGA, FTIR. as-prepared utilized as a abatement It observed ...

A 28 year-old man presented with sudden visual loss in his left eye. Best-corrected visual acuity was 20/20 in the right eye and 20/400 in the left eye. Fundus examination showed a whitish retinal lesion of the superotemporal quadrant involving the supero-temporal retinal vein branch with mild vitritis. Fluorescein angiography confirmed active retinochoroidal inflammation (black arrow) with del...

In this research, the effects of different color intensities, anoxic + anaerobic times and types of substrate on color removal effectiveness were studied using 16-litre bench scale sequencing batch reactor (SBR) anoxic + anaerobic/aerobic models. The systems were fed with a synthetic wastewater containing 500 mg/l of COD, 50 mg/l of N, 15 mg/l of P along with 10, 40 and 80 mg/l of reactive diaz...

In the present study, the biobleaching potential of white rot fungus Cordyceps militaris MTCC3936 was investigated. For preliminary screening, decolorization properties of C. militaris were comparatively studied using whole cells in agar-based and liquid culture systems. Preliminary investigation in liquid culture systems revealed 100% decolorization achieved within 3 days of incubation for rea...

Oxidation of pollutants in waste water by photo-Fenton reaction has proven an ecofriendly and economical method. Oxidation of amido black – 10B, (an acid dye of azo series) using photoFenton reagent was investigated under ambient conditions. The effect of different parameters like the concentration of ferric ion, amido black10B and hydrogen peroxide, pH, light intensity etc. on the reaction rat...

Background and purpose: The textile dyes are considered as important pollutants due to the toxicity on human and environment. Therefore, the dye removal from industrial effluents is necessary. This study evaluates the ability of Azolla for the adsorption of acid black 1 (AB1) dye from aqueous solution. Materials and Methods: This was an experimental-laboratory study. The Azolla biomass was sun ...

The presence of synthetic dyes in textile wastewater is a problematic issue for environmentalist. Nowadays, dye removal is practiced via different methods. Among all these methods, biodecolorization is an ideal technique. The present research apples vermicompost microflora to remove reactive black- C, pH = 7, and under anaerobic condition. At 36h, removal efficiencies of 94.79%, 94.06%, and 93....
