The evaluation of the resistance of isolates to chitosan gel
revealed that the polymer was lethal to UFPEDA 840 at the lowest
tested concentration (1%), whereas UFPEDA 831 supported up to 4%
during 24 h. Based on these results, UFPEDA 840was excluded from
subsequent tests, leaving UFPEDA 831 as the sole candidate for
development of a potential product.
