Functional properties of themicroalga Chlorella vulgaris and bifidobacteria, and their potential for development of functional foods

Popis výsledku v původním jazyce

The market for new functional foods and dietary supplements with probiotics is rapidly evolving, with a current emphasis on using natural sources. Chlorella vulgaris is a promising source of nutritionally valuable substances, including not only proteins or carbohydrates, but also vitamins, pigments, antioxidants, unsaturated fatty acids, etc. Therefore, the presented study assessed different properties of C. vulgaris and its combination with bifidobacteria (Bifidobacterium animalis subsp. lactis BB-12®, Bifidobacterium animalis subsp. lactis CCDM 93, Bifidobacterium faeces CCDM 486, Bifidobacterium breve CCDM 562) with the goal to develop new functional foods. The growth ability of four bifidobacteria was evaluated in basal medium, whey and milk enriched by 1.0 % (w/v) chlorella powder. The evaluation was based on production of lactic and acetic acids, viable cell (CFU/ml) and change of pH of the cultivation media. Subsequently, the effect on lipid metabolism of Prague hereditary hypercholesterolemic rats fed a high-fat diet with chlorella and probiotic B. animalis subsp. lactis BB-12® were determined. After 8 weeks, the significant synergistic effects of chlorella and BB-12® on triglyceride levels in rat heart, liver and serum were detected (P<0.05). All the four strains tested produced a significantly higher concentrations of lactic and acetic acids (P < 0.05) in comparison with basal medium, whey and milk without supplementation of 1 % (w/v) Chlorella vulgaris. The observed trend also correlated with the pH values. The presented results demonstrate that Chlorella vulgaris has a positive growth effect of all tested Bifidobacterium strains and their combination influence favourably lipid metabolisms, therefore the combination of probiotics and algae might have a significant potential in the development of new functional foods and dietary supplements with health benefits.
