Biosynthesis and characterization of bacterial cellulose membranes presenting relevant characteristics for air/gas filtration

The production of bacterial cellulose has gained prominence in recent years as an alternative for the sustainable materials that might be used diverse processes and applications. present study discusses possibility producing tailored membranes situ, relevant characteristics potential use air/gas filtration. Various cultivation characterization studies were performed to ascertain suitability Komagataeibacter sp. FXV3, NFXK3, K. intermedius LMG 18909 strains produce with properties. Subsequently, films produced freeze-dried obtain stable membranes, extensively characterized their physicochemical results obtained showed different enabled synthesis distinctive morphological Moreover, carbon sources ethanol concentrations employed media led modifications by strains, which further impacted membrane morphology and, ultimately, gas filtration behavior. All synthesized fully characterized, showing adequate mechanical properties, tested permeance N2, CO2 O2, opening perspectives
