Abstract
Wastewater treatment using biopolymersproduced by bacteria is an emerging approach that seeks tooffer sustainable and efficient solutions for wastewatermanagement. For this reason, the present work evaluated theefficiency of dextran as a in the treatment of industrialwastewater. A molecularly identified strain whose 100%identity corresponded to the species Leuconostocpseudomesenteroides was used for this purpose. The flocculantactivity of dextran was evaluated using doses of 20 and 40 ppm,while a concentration of 5 ppm was used for aluminum sulfate.Subsequently, the contents were transferred to 250 mLcylindrical test tubes and left to stand for 96 h. To analyze theeffectiveness of these treatments in water purification,parameters such as turbidity, dissolved oxygen, and total solidswere assesse in the treated samples and compared to anuntreated control. While aluminum sulfate was found to bemore effective in reducing turbidity and total solids, dextrandemonstrated promising results, particularly at higherconcentrations, where an enhancement in dissolved oxygenefficiency was observed. Additionally, dextran, at aconcentration of 40 ppm, was identified as the most effectivetreatment in reducing fecal coliforms. In summary, dextran ispresented as a promising option for wastewater treatment,highlighting its efficacy and environmental benefits.
