This paper aims to establish direct and predictive methods (statistical) the possibility of obtaining lactic bacteria Lactobacillus delbrueckii var. bulgaricus in higher amounts by using culture medium enriched with carbohydrates in different percentages, for using these in obtaining organic products. The results led to the selection of MRS culture medium enriched with 1% glucose, 2% lactose and 3% maltose as a substrate in order to use multiplication of lactic bacteria isolated from organic milk, collected from organic farms in the area of Sibiu, Romania.

Wines contain a wide range of aromatic compounds, each having its share in the characterization of the end product. This paper aims at highlighting the phenolic compounds that are present in three types of wine from the Apold Vineyard, compounds that have been determined by modern chromatographic methods. Anthocyanins, flavans, flavones and flavonoids, phenolic acids and microphenolic compounds have been determined in three wines: Pinot gris, Neuburger and Furmint. The results have led to the characterization of these wines and their classification according to the parameters acknowledged by the international authorities.

This paper aims to establish the conditions of hygiene of the breeding farm from Sadu, Romania, by monitoring the microbiological indicators such as hospital attendant TNG, total number of yeasts and molds, and total number of coliforms in shelters and on milking equipment. By monitoring air microbial flora, containers used for milking and hygiene of livestock (sheep and cow) values are found by the standards in force, with the recommendation to improve the quality of these parameters in order to reduce the values at lower limits.
