Abstract:

The therapeutic application of bromelain is limited due to its sensitivity to operating conditions such as high acidity, gastric proteases in the stomach juice, chemicals, organic solvents and elevated temperature. We hypothesized that bromelain immobilized on probiotic bacterial spores would show enhanced therapeutic activity through possible synergistic or additive effects. In this study, the oedema inhibition potential of bromelain immobilized on probiotic Bacillus spores was compared to the free enzyme using the carrageenan paw oedema model with Wistar rats. In batch A rats (carrageenan-induced inflammation 30 min after receiving oral treatments), group 7 rats treated with a lower dose of spore-immobilized bromelain suspension showed the highest oedema inhibition, 89.20 ± 15.30%, while group 4 treated with a lower dose of free bromelain had oedema inhibition of 60.25 ± 13.00%. For batch B rats (carrageenan-induced inflammation after receiving oral treatment for three days), group 7 rats treated with a lower dose of spore-immobilized bromelain suspension showed higher inhibition percentage (81.94 ± 8.86) than group 4 treated with a lower dose of free bromelain (78.45 ± 4.46) after 24 h. Our results showed that used alone, the enzyme and the spores produced oedema inhibition and improved the motility of the rats. The spore-immobilized bromelain formulation performed approximately 0.9-fold better than the free bromelain and the free spores at the lower evaluated dose.
