A sustainable bioprocess to produce bacterial cellulose (BC) using waste streams from wine distilleries and the biodiesel industry: evaluation of BC for adsorption of phenolic compounds, dyes and metals

Biotechnology for Biofuels and Bioproducts, Journal Year: 2024, Volume and Issue: 17(1)

Published: March 12, 2024

Abstract Background The main challenge for large-scale production of bacterial cellulose (BC) includes high costs interlinked with raw materials, and low rates. valorization renewable nutrient sources could improve the economic effectiveness BC fermentation while their direct bioconversion into sustainable biopolymers addresses environmental pollution and/or resource depletion challenges. Herein a green bioprocess was developed to produce in amounts rather unexplored strain Komagataeibacter rhaeticus, using waste streams such as wine distillery effluents (WDE) biodiesel-derived glycerol. Also, evaluated bio-adsorbent phenolics, dyes metals removal enlarge its market diversification. Results significantly affected by WDE mixing ratio (0–100%), glycerol concentration (20–45 g/L), type media-sterilization method. A maximum 9.0 g/L, productivity 0.90 g/L/day water holding capacity 60.1 g water/g dry BC, achieved at 100% ≈30 g/L crude samples showed typical vibration bands average fiber diameters between 37.2 89.6 nm. dephenolize adsorb phenolics during reached respectively, up 50.7% 26.96 mg gallic acid equivalents/g ( in-situ process). produced also investigated dye metal removal. highest yellow 17 (54.3%) recorded when 5% applied bio-adsorbent. Experiments performed multi-metal synthetic wastewater that remove 96% Zn 97% Cd. Conclusions This work demonstrated low-carbon approach low-cost, biodegradable BC-based bio-adsorbents, without any chemical modification. Their potential wastewater-treatment-applications highlighted, promoting closed-loop systems within circular economy era. study may serve an orientation future research towards competitive or targeted adsorption technologies treatment resources recovery.
