The viability of both test-cultures protected with acacia gum was higher than unprotected cultures in all samples during the storage.For example, after storage at 35 °C for 5 days 13% of MRSA was recovered from wool filled with acacia gum, while only 7.4% of MRSA was found in wool samples. Number of viable cells of both test-cultures was the lowest after the storage on cotton in comparison with wool,rayon and polyester. The rapid loss of microorganism's viability during the storage was reported by other authors.No viable bacteria were found after 48 h of storage on viscose (rayon) at room temperature.In our experiments, storage of MRSA on rayon with acacia gum for 48 h at 25 °C results in 51.3% of viable bacteria. Rayon with acacia gum was also effective for storage of B. anthracis spores.Our results show that after 37 weeks of storage in rayon with acacia gum at 50 °C only 23% of spores were inactive. According to the data, presented by Fernelius et al. (1958), 99% of B. anthracis spores in liquid medium were inactivated in 9 weeks at 50 °C.
