Test 1 - Survivability of Bacteria

To find out how the samples are able to resist the survivability of bacteria, a sample swatch survival test was carried out using two test organisms (Escherichia coli and Staphylococcus aureus). Starting from 24 hours to 120 hours of incubation at 37⁰C, the survival of known test bacterial concentration in all the four samples was assayed over time, every 24 hours. Survival test was also carried out using worn socks. The results of test indicate that the survivability of bacteria on cotton was more lasting compared to rayon and bamboo. The survivability of bacteria on 50/50% Bam/co is similar to bamboo.

The general survivability of the test organism E. coli, was less compared to S. aureus. This analysis indicated that bamboo potentially resists the colonization of both E. coli and S. aureus from the second day of incubation, which is an indication of bamboos antimicrobial resistance characteristic.
