Methods of binding antibacterial drugs to the surface of cellulose without the use of oxidizing agents to prevent the occurrence of wound infections have been studied. The immobilization of gentamicin in the complex of partially denatured albumin in the composition with bacterial cellulose has been analyzed. The study was carried out on samples of cellulose synthesized by Gluconacetobacter hansenii . Albumin served as a binding agent, which was used to impregnate cellulose samples, which were then denatured. Using PCR amplifi cation CFX (BioRad), the optimal denaturation temperature was selected. The effectiveness of the immobilization of albumin in the thickness of the cellulose was assessed by staining it with the luminescent dye SYPRO® Ruby Protein Gel Stain, followed by transilluminator detection. Bacterial cellulose impregnated with undenatured albumin was used as a control. Albumin immobilization in bacterial cellulose was observed at temperatures of 65– 95 °C. The antibacterial activity of the complex “cellulose + albumin + gentamicin” was evaluated using a test strain of bacteria Staphylococcus aureus ATCC 25923. The growth inhibition of the test strain of bacteria was observed in all tests with bacterial cellulose in combination with partially denatured albumin and gentamicin. In control samples, in which gentamicin was not immobilized as part of partially denatured albumin, growth inhibition zones of Staphylococcus aureus ATCC 25923 were not noted. It was concluded that by partial denaturation of albumin it is possible to delay antibacterial drugs in the thickness of bacterial cellulose for their further release. A new version of the material suitable for the production of implants and bandages based on bacterial cellulose gel with antibacterial properties is proposed. Dressings based on a composite of bacterial cellulose, albumin and gentamicin are most relevant for the treatment of burns. The presence of gentamicin in their composition is also relevant for the prevention of bacterial infections.
