Various types of functional yogurts were obtained from normalized milk (with normalized lipid content) and a standardized probiotic consortium of probiotic bacteria named ABY3. All the types of yogurts obtained contained prebiotics from black or red rice; malt of barley, rye, wheat; or wheat bran. The physico-chemical analyses of all the functionalized products obtained showed that all of them met the quality standard for yogurt products. However, the sensorial analyses showed that the products obtained from black and red rice were of very good quality. The biological analyses indicated that all the types of products contained live probiotic bacteria, but wheat bran and red rice could increase their numbers. Tests performed on tumor cell line Caco-2 with corresponding postbiotics revealed cytotoxicity greater than 30% after 48 h of exposure in the case of yogurts obtained from milk with 0.8% lipid content and red rice or blond malt of barley. In the case of yogurts derived from milk with 2.5% lipid content, only the variants that contained blond malt of rye or wheat became cytotoxic against the Caco-2 cell line.

Phytosanitary products obtained from natural extracts represent an alternative, especially in the case of preservation of the products obtained from organic farming. The purpose of this work was to test the antifungal activity of three extracts obtained from a plant from Plantaginaceae family, obtained according to the methodology presented by Radu et al. [1]. The tests were performed in vitro on phytopathogenic fungi that cause alteration of the citrus fruits, such as Penicillium sp.; and Aspergillus sp. The methodology used was that of diffusive discs impregnated in sterile solutions containing 3% of the solid extract, dissolved into an inert solvent (respectively Dimethyl Sulfoxide) [2][3][4]. After inoculation with the tested microorganism and treatment with the analyzed phytoextract, the growth of microorganisms was monitored for two weeks. The obtained results showed that the tested extracts inhibit the development of the species of Penicillium citrinum, Penicillium digitatum, and Aspergillus niger. These effects have maintained for 72 hours in the case of the above microorganisms. After 2 weeks the antifungal effect of the analyzed extracts was reduced at 78.5% in the case of Penicillium citrinum, at 83.5% in the case of Penicillium digitatum and respectively at 57.9% in the case of Aspergillus niger. In conclusion, the best results are obtained at the treatment of Penicillium species which attack the citrus fruits, with studied plant extracts. Here is needed a deeper research, in order to develop a bioproducts from Plantaginaceae indigenous plants, with a role in protecting and preserving of citrus fruits.Acknowledgments: This paper was prepared with the financial support of the project PFE no 31/2018.
