Eriochrome Black T dye presents an environmental challenge due to its resistance to degradation, affecting water quality and aquatic life. Simultaneously, inefficient management of agro-industrial waste contributes to pollution and climate change. The need to innovate in the treatment of pollutants and the recovery of waste is crucial, promoting the circular economy and environmental protection, highlighting the importance of sustainable and effective solutions. The objective of this research is to use a bacterial cellulose biocomposite through the fermentation of hydrolysates derived from artichoke and asparagus waste. This biocomposite was intended for the elimination of the Eriochrome Black T dye under laboratory conditions. Komagataeibacter rhaeticus was isolated from Kombucha tea SCOBY. It was genetically identified by PCR of the 16S rRNA gene. The asparagus and artichoke waste were conditioned and ground for acid hydrolysis, obtaining fermentable sugars. For the production of bacterial cellulose, inoculum doses of 1 to 20% and incubation times of 3 to 22 days were experimented, using a response surface design. For biosorption, 0.5 g of bacterial cellulose and alginate biocomposites were used in EBT solutions at 10 mg/L, evaluating the pH at 5, 7 and 9. The assays were incubated at 30°C and 150 rpm for 24 hours. The removal efficiency was evaluated by UV-VIS spectrophotometry, calculating the percentage of dye removal. The study revealed that bacterial cellulose biocomposites derived from artichoke waste achieve notable efficiency in the biosorption of the Eriochrome Black T dye, reaching up to 82.01% removal at pH 5. This study highlights the production and functionality of the biocomposites, proposing an innovative and sustainable solution for the treatment of water contaminated with industrial dyes.
