Characterization of Bacterial Cellulose fabricated with Vietnamese ingredients for potential textile applications

Abstract

This research explores the fabrication and characterization of bacterial cellulose (BC), with a distinct emphasis on leveraging indigenous Vietnamese bio-mass sources. A diverse sample library of over 150 BC samples was gathered, with six samples selected for objective evaluation based on the standard test methods. These samples were subjected to characterization techniques including Scanning Electron Microscopy (SEM), Bursting Strength, Thickness, Fourier Transformation Infrared (FTIR) and pH level to explore potential applications in textiles. Moreover, the growth medium or SCOBY (Symbiotic Culture of Bacteria and Yeast) mother, from which the BC was cultivated, was analyzed to identify the constituent bacterial and yeast strains. The notable aspects of this study were: (a) the use of local Vietnamese ingredients (i.e., sugar and teas) as nutrient sources for BC cultivation, and (b) exploring the impact of local crafted solutions for drying food-based products akin to rice wraps, on the properties of BC. The study’s outcomes established a deeper comprehension of the morphological, mechanical, and chemical attributes of BC, as well as the microbial dynamics within the SCOBY mother. This exploration not only augments the existing knowledge on BC's potential in material design but also paves the way for further research on the influence of local ingredients on biomaterial production, thereby contributing to the burgeoning field of sustainable material design innovation within a localized context.

Treatment of Oily Effluents Using a Bacterial Cellulose Membrane as the Filter Bed

“…The range from 1159 cm -1 to 1002 cm -1 corresponds to C-O bonds. Comparing these data to those of other researchers that analysed BC without the presence of oil [16,[30][31][32], several similarities and very few differences were evident. This is due to the fact that the emulsion submitted to filtration was prepared using OCB2, which is an oil with chemical bonds similar to the bonds found in the BC membrane.…”
