Abstract
Lactobacillus acidophilus is a probiotic commonly used in aquaculture to enhance the growth and immune system of aquatic species through the synthesis of various enzymes, and antimicrobial compounds like lactic acid. Traditional method of growing L. acidophilus involes using the De Man-Rogosa-Sharpe (MRS) medium. However, L. acidophilus belongs to a non-spore forming group, which make it vulnerable to stress conditions, especially during the usage process. Therefore, the present study aimed to improve the survival rate, antibacterial activity, and enrich the polyunsaturated fatty acids (PUFAs) content of L. acidophilus LB when cultured in an algae-supplemented medium, thus increasing its benefits in aquaculture applications. Using different algae biomass species as an alternative to MRS medium for the growth of L. acidophilus LB, the results showed that Spirulina platensis promoted the highest density of L. acidophilus LB. When grown in (S. platensis + glucose) medium, L. acidophilus LB produced the highest lactic acid concentration of 18.24 ± 2.43 mg/mL and survived in extreme conditions such as 4% NaCl, pH 1.0-2.0, and 50 ºC, and inhibited 99.82 ± 0.24% of Vibrio parahaemolyticus population after 2 days of treatment. Additionally, it was observed that the PUFAs content, specifically omega-6, and -7, also increased in the fermentation mixture as compared to the control sample. These findings highlighted the potential of utilizing the cyanobacteria S. platensis as an alternative, eco-friendly growth substance for L. acidophilus LB to enhance its bioactivity and viability under extreme conditions.

Prebiotic and Immunomodulatory Properties of the Microalga Chlorella vulgaris and Its Synergistic Triglyceride-Lowering Effect with Bifidobacteria. FERMENTATION 2021.

Abstract
The microalga Chlorella and strains of Bifidobacterium have been used in human or animal food supplements for decades because of their positive health effects. The presented study assessed different properties of C. vulgaris and its combination with bifidobacteria with the aim to develop new functional foods. The growth of four bifidobacteria strains in milk and whey supplemented with 1.0% (w/v) C. vulgaris and the immunomodulatory effects of aqueous Chlorella solutions (0.5%, 1.0%, and 3.0%) on human peripheral mononuclear cells were evaluated. Furthermore, synergistic effects on lipid metabolism of rats fed a high-fat diet with Chlorella and B. animalis subsp. lactis BB-12® were analysed. Chlorella had a positive growth-promoting effect on the tested bifidobacteria (p < 0.05), and significantly increased the secretion of inflammatory cytokines (tumor necrosis factor-α, interleukin-10, and interleukin-6), depending on the concentration of Chlorella (p < 0.05). After 8 weeks, significant synergistic effects of Chlorella and bifidobacteria on triglyceride levels in rat heart, liver, and serum were observed (p < 0.05). These results demonstrate that various combinations of Chlorella and bifidobacteria have significant potential for the development of new fermented products, dependent on the algal species, probiotic strain, application form, and concentrations for acceptable sensory quality for consumers.

Functional Properties of Chlorella vulgaris, Colostrum, and Bifidobacteria, and Their Potential for Application in Functional Foods. APPLIED SCIENCES-BASEL 2021.

Abstract
The market for new functional foods and food supplements is rapidly evolving, with a current emphasis on using natural sources. Algae, probiotics, and colostrum are rich sources of nutrients and bioactive compounds with positive effects on human and animal health. To determine the potential for developing new functional foods combining these components, we evaluated their synergistic effects. We assessed the growth of selected bifidobacteria in a medium supplemented with Chlorella vulgaris and its immunomodulatory and cytotoxic effects on the human peripheral mononuclear cells and colon cancer cell lines Caco-2 and HT29. The hypocholesterolemic effects of Chlorella powder and bovine colostrum fermented by Bifidobacterium animalis subsp. lactis BB12® on lipid metabolism in rats fed a high-fat diet were also determined. Chlorella addition promoted Bifidobacteria growth, with significantly increased inflammatory cytokine (TNF-α and IL-6) levels following 1.0% (w/v) Chlorella stimulation. Rats fed diets containing fermented colostrum with 0.5% (w/v) added Chlorella powder exhibited significantly decreased triglyceride, very low-density lipoprotein, and alanine and aspartate aminotransferase levels, compared to those of the control group. These results support that C. vulgaris is not cytotoxic in intestinal cell models and affords prebiotic and immunomodulatory effects, as well as synergistic triglyceride-lowering effects with bovine colostrum and B. animalis subsp. lactis BB-12.
