Abstract
This study mainly aimed to evaluate the antibacterial impact of bacterial cellulose (BC) including dendrimer, chitosan, Henna, Green tea and Malva sylvestris in various bacteria such as Staphylococcus aureus and Pseudomonas aeruginosa. The produced bacterial cellulose was evaluated by antimicrobial (AATCC 25923 and AATCC 27853), cytotoxicity, swelling, drug delivery, scanning electron microscopy (SEM) and Fourier Transform Infrared (FTIR) spectroscopy tests. Antibacterial activity raised with increasing concentration of herbals and the most of antimicrobial effect belonged to G. tea. Cytotoxic test demonstrated that all of the samples did not have cytotoxic effect and viability percent for sample of BC with Henna, G. tea, and M. sylvestris extract were respectively 95.87%, 94.69% and 90.64%. Among the samples, the G. tea sample has the most swelling. In addition, delivery of the drug in water and phosphate buffer medium was the controlled release. Additionally, the most of the release related to the herbal drug Henna. SEM results showed BC with a highly porous three dimensional network structure. The considerable role of chitosan and dendrimer was evident in drug uptake and release. FTIR analysis demonstrated the presence of active groups in BC structure.
