“…This result is also consistent with other results, which demonstrated that dye decolorization significantly increased when shifted from stationary to shaking culture conditions . This result is in contrast to that described by Saratale et al This may be because shaking increases oxygen and substrate transfer to the bacterial cells, thereby easing bacterial growth and accelerating metabolic processes . Prediction of decolorization behavior of the bacterial isolate was performed using UV–vis spectroscopy where it was noticed that there was a decrease in the peak height at the same wavelength by the progress of time (Figure ), indicating the biosorption of MO by bacterial cells, which was confirmed by orange‐colored cell pellets (Figure ).…”

“…[36,43] This result is in contrast to that described by Saratale et al [41] This may be because shaking increases oxygen and substrate transfer to the bacterial cells, thereby easing bacterial growth and accelerating metabolic processes. [44,45] Prediction of decolorization behavior of the bacterial isolate was performed using UV-vis spectroscopy where it was noticed that there was a decrease in the peak height at the same wavelength by the progress of time (Figure 3), indicating the biosorption of MO by bacterial cells, which was confirmed by orange-colored cell pellets (Figure 4). In this work, comparative trials with live and dead cells by UVvis spectral analysis of MO by time revealed a high decolorization capacity of live biomass alongside with dead biomass and confirmed that the decolorization process is attributed to biosorption and adsorption pathways ( Figure 5).…”

Due to the toxicity and mutagenicity of methyl orange (MO), it is necessary to eliminate MO from wastewater. A bacterial strain is isolated and identified that possesses a high MO decolorization ability. Furthermore, the cultural requirements and the decolorization behavior of the bacterial isolate are investigated. Potassium‐iodide‐doped hydroxyapatite (KI‐doped HAp) nanoparticles are synthesized and characterized. The enhancement of the decolorization rate using KI‐doped HAp nanoparticles is experimentally confirmed. The microbial toxicity assessment is evaluated against Bacillus subtilis, and the bacterial isolate is identified as the Enterococcus faecalis strain Kilany MO under accession number KY780590. This strain shows maximum decolorization of MO (86.4%) at 400 mg L−1, pH 6, and 30 °C for 48 h under static conditions. In addition, being extremely tolerant of concentrations of MO of up to 1000 mg L−1 or more, E. faecalis exhibited decolorizing activity through biosorption rather than adsorption. Scanning electron microscopy and energy dispersive X‐ray spectra revealed that KI‐doped HAp nanoparticles are nanorods that are 50–100 nm in size with a Ca/P molar ratio of 1.833. KI‐doped HAp nanoparticles enhanced decolorization, yielding a maximum removal of 95% within 48 h. A microbial toxicity study revealed that the bacterial metabolites are less toxic than MO. Hence, the potential of E. faecalis to withstand high concentrations of MO, especially in the presence of nanoparticles, may start a new trend in wastewater bioremediation strategy.

The batik industry in Indonesia has an IKM (Small and Medium Industry) scale so that it does not yet have adequate waste treatment. In the long term, waste is disposed of directly into the environment which can damage aquatic ecosystems and harm human health. Textile wastewater has a complementary picture and has a deep color. One of the most dangerous heavy metals contained in textile waste is hexavalent chromium (Cr(VI)). Several ways can be done to reduce hexavalent chromium (Cr(VI)) by bioremediation. Based on the results of the literature review, it shows that the bioremediation agents from single isolate microorganisms that are most effective in degrading chromium with high efficiency are Bacillus subtilis and Pseudomonas aeruginosa. The most effective consortium servers with constant reduction rates are the consortium of bacteria genus Mesophilobacter, Methylococcus, Agrobacterium, Neisseria, Xanthobacter, Deinococcus, Sporosarcina, and Bacillus by reducing BOD levels by 85.71%. The hexavalent chromium-degrading microorganisms are characterized by the presence of chromate reductase enzymes, mostly gram-negative bacteria, and a high growth rate.

“…Some of them can be present in solutions as neutral, mono, or bivalent negatively charged ions [ 7 ]. Industrial scale production of these chemicals is easy and non-expensive, therefore, such colorants have been used excessively in industries worldwide [ 8 , 9 ]. Particularly, Brilliant Blue FCF (BB) has been extensively used as a component of food products like sweets, dairy products, and drinks.…”

The main goal of this experimental work is screening of different natural and synthetic nanomaterials and biopolymers that may improve elimination of stable micropollutants from water phase. In this work, as a target chemical acting as the micropollutant molecule, the Brilliant Blue (BB) dye was selected. We tested different active matrices dispersed in water phase including activated carbon (AC), lyophilized graphene oxide (GO), β-cyclodextrin (CD), raw dandelion pappus (DP), microcrystalline cellulose(MC), and raw pine pollen (PP), as well as two types of Egyptian Blue mineral pigments (EB1 and EB2). Graphene oxide and Egyptian Blue nanomaterials were synthesized in our laboratory. We investigated potential application of such nanoparticles and biopolymer conglomerates as additives that may tune the activated sludge (AS) microorganisms or duckweed water plant (DW) and increase efficiency of micropollutants removal from wastewater. Studied nanomaterials/biopolymers were used in two different experimental modes involving real activated sludge microorganisms (24 h experiment) as well as duckweed plant (16 day experiment). Quantitative data of BB were obtained using microfluidic type device based on micro-TLC plate. This approach enabled direct determination of target component without sample pre-treatment like pre-concentration or pre-purification. Within single analytical run calibration line, retention standard spots (methyl red) and multiple samples were analyzed simultaneously. Due to the multivariate nature of these experiments, quantitative data were explored with chemometric tools including AHC (agglomerative hierarchical clustering), PCA (principal component analysis), and FA (factor analysis). Experimental data and multivariate calculations revealed that BB is strongly resistant on biodegradation, however, inclusion complexes formation with β-cyclodextrinmay induce degradation of this dye in the presence of duckweed. It is hoped that results of our experimental work can be used for designing of future experiments for fast screening of different additives and improvement of technological processes, focusing on purification of sewage and water from micropollutants.
