摘要： The present invention relates to a process wherein one or more dye precursors, e.g., indole, are provided to a textile and converted by one or more enzymes, e.g., an oxidizing enzyme, to provide the textile with a dye, e.g. indigo. At least the oxidizing enzyme is a hybrid enzyme including a binding domain that is suitable to bind the enzyme to the textile and/or increase the affinity of the enzyme for the textile, in particular, a cellulose binding domain (CBD).

摘要： 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.
