Fermentability of brown rice and rice bran for growth of human Lactobacillus plantarum NCIMB 8826
The growth of the lactic acid probiotic strain Lactobacillus plantarum NCIMB 8826 isolated from the human gut on rice-based media has been investigated. Fermentation broths were obtained from the whole grain brown rice and rice bran of two Thai rice cultivars, RD6 (glutinous) and RD17 (nonglutinous)...

| Sumario: | The growth of the lactic acid probiotic strain Lactobacillus plantarum NCIMB 8826 isolated from the human gut on rice-based media has been investigated. Fermentation broths were obtained from the whole grain brown rice and rice bran of two Thai rice cultivars, RD6 (glutinous) and RD17 (nonglutinous). The rice used was not germinated and fermentations were carried out in a single step without growth supplementation. L. plantarum grew well in all tested broths, and a final biomass value of approx. 10.4 log CFU/mL was obtained. In addition, biomass production and substrate depletion were satisfactorily modelled using an unstructured mathematical model. There were no statistical differences observed among the four rice media. The results confirm that brown rice and rice bran are suitable substrates for the culture of the probiotic L. plantarum NCIMB 8826. Rice bran, currently a by-product of the traditional cereal processing industry, has shown similar fermentability to brown rice. This indicates that rice bran or rice bran extracts could be used in new probiotic food developments, while probably still maintaining other functional properties of the bran. |
