Resumen:
A technique developed to determine naphthalene
dioxygenase (NDO) activity was optimized and used to study the
biotransformation of indole to indigo by Pseudomonas sp. J26 whole
cells. The maximum production of indigo was achieved at 25 °C using 2.5
mM indole when J26 was grown in the complex medium JPP, while indole
concentrations higher than 4 mM proved toxic for cells. The maximum rate
of indigo production was 0.56 nmol min-1 mg dry biomass-1, obtaining
75.5 μiM of indigo after 8 h of incubation, while a maximal
concentration (138.1 μiM) of indigo was obtained after 20 h.
