In this study, we report the adsorption process of Congo Red (CR) dye by calcined Layered Double Hydroxide (ZAC) at 550°C. The urea hydrolysis method was applied to produce highly crystalline Zn2Al-LDH. Samples characterisation carried out X-ray diffraction (XRD), Thermogravimetric/differential thermal analysis (TG/DTA), and Fourier transform infrared spectroscopy (FTIR). results show that CR o...

In the present study, Chryseobacterium geocarposphaerae DD3 isolated from textile industry dye effluent in West Bengal, India, displayed significant tolerance to sulfonated di-azo Congo red (CR), up 500 ppm. The optimum decolourisation revealed that C. was capable of 96.52% 0.2 g L−1 CR within 12 h treatment presence 5 glucose as supplementary carbon source. Biodegradation analysis decolourised...
