Bacterial cellulose production: valorization of wastewater and life cycle asses...
Dourado, Fernando; Forte, Ana Cristina Figueiras; Mota, André; Neto, Belmira; Ferreira, Eugénio C.; Silva, Francisco Almeida Garrett SoaresLow-cost substrates, most from agro-industrial wastes, have increasingly been exploited as nutrient sources for the fermentation of bacterial cellulose (BC), an appealing approach from an economical and environmental point of view. However, these wastes carry a very high organic load, which, while advantageous for the fermentation, generate high organic load wastewaters as well, which require proper treatment b...
Trends on the cellulose-based textiles: raw materials and technologies
Felgueiras, Catarina; Azoia, Nuno G.; Gonçalves, C.; Gama, F. M.; Dourado, FernandoThere is an emerging environmental awareness and social concern regarding the environmental impact of the textile industry, highlighting the growing need for developing green and sustainable approaches throughout this industrys supply chain. Upstream, due to population growth and the rise in consumption of textile fibers, new sustainable raw materials and processes must be found. Cellulose presents unique struc...
Study and valorisation of wastewaters generated in the production of bacterial ...
Soares da Silva, F. A. G.; Oliveira, João Vítor; Felgueiras, Catarina; Dourado, Fernando; Gama, F. M.; Alves, M. M.Two culture media were tested for the production of bacterial nanocellulose (BNC) under static culture fermentation, one containing molasses (Mol-HS), the other molasses and corn steep liquor (Mol-CSL), as a source of carbon and nitrogen, respectively. These are low-cost nutrients widely available, which provide very good BNC productivities. However, the use of these substrates generates wastewaters with high o...
