Bacterial cellulose is in demand in modern medicine

Researchers from the Siberian Federal University (SFU) isolated and described the new strain of acetic acid bacteria that may be used in bacterial cellulose production. Cellulose without impurities is used for the dressings and fabric production.

The biological compatibility of bacterial cellulose makes it possible to make from it substrates for cells cultivation and to use grown structures for skin regeneration, said Svetlana Prudnikova, professor of the biotechnology department of SFU.

Scientists isolated the new strain of acetic acid bacteria from the «tea fungus» — Medusomyces gisevi. Acetic acid bacteria, to which the found strain belongs, oxidize ethanol in fermentation products and process glucose. «The strain is more productive than analogues, which were previously isolated by foreign and Russian scientists. Synthesizing a large volume of cellulose it is able to grow on a variety of carbon sources, not limited by substrates containing glucose and ethanol,» the SFU press service said.

The discovery can help reduce the cost of bacterial cellulose. The study results are published in Biology.
