Biopolymers Derived from Forest Biomass for the Sustainable Textile Industry
Dias, J. C.; Marques, Susana; Branco, Pedro C.; Rodrigues, Thomas; Torres, Cristiana A.V.; Freitas, Filomena; Evtuguin, Dmitry; Silva, CarlaABSTRACT: In line with environmental awareness movements and social concerns, the textile industry is prioritizing sustainability in its strategic planning, product decisions, and brand initiatives. The use of non-biodegradable materials, obtained from non-renewable sources, contributes heavily to environmental pollution throughout the textile production chain. As sustainable alternatives, considerable efforts ...
Kinetics of production and characterization of the fucose-containing exopolysac...
Torres, Cristiana A.V.; Marques, Rodolfo; Antunes, Sílvia; Alves, Vitor D.; Sousa, Isabel; Ramos, Ana Maria; Oliveira, Rui; Freitas, FilomenaA fucose-containing exopolysaccharide (EPS) was produced by the bacterium Enterobacter A47 using glycerol byproduct from the biodiesel industry. The analysis of kinetic data suggested a partially growth associated EPS synthesis model. Although the EPS was composed of fucose, galactose and glucose at all cultivation stages, their relative proportion has varied considerably during the run. At the beginning (24 h)...
Fucose-containing exopolysaccharide produced by the newly isolated Enterobacter...
Freitas, Filomena; Alves, Vitor D.; Torres, Cristiana A.V.; Cruz, Madalena; Sousa, Isabel; Melo, Maria João; Ramos, Ana M.; Reis, Maria A.M.Enterobacter strain A47 (DSM 23139) was found to produce a fucose-containing exopolysaccharide (EPS). The EPS is composed of fucose, galactose, glucose, pyruvate, succinate and acetate in the molar ratios 1.6:1.3:1.1:1.2:0.7:1.5. It is a high molecular weight (5.8×106) homogeneous biopolymer, as indicated by the low polydispersity value (1.3). The steady shear flow properties of the EPS aqueous solutions are si...
