| description | The present invention refer to a process for the production of microbial cellulose using a waste textile material, for example 100% cotton or blended cotton/polyester/elastane waste textile, said waste textile material comprising cellulose, comprising the following steps: providing an amount of said waste textile material; pre-treating said waste textile material with an aqueous solution comprising NaOH and urea, to obtain a pre-treated fabric, wherein said step of treating said waste textile with an aqueous solution comprising NaOH and urea is carried out at a temperature ranging from -25°C to +30°C; treating said pre-treated fabric with cellulase enzymes, to convert said cellulose into glucose, whereby a mixture including glucose is obtained; preparing a culture medium comprising said mixture including glucose; inoculating said culture medium with microbial cellulose producing microorganisms; and incubating said microbial cellulose producing microorganisms to obtain microbial cellulose. |
