06.00.00 Agricultural sciences
DescriptionThis article presents the possibilities of using organic fertilizers, which allow you to recharge grape raw material with biologically active substances and improve the nutritional value of wine production. The influence of organic fertilizers on activation of process for detoxification of soil toxic compounds has been measured, ensuring food safety of raw materials for the production of grape wine products by reducing of hazardous chemicals. The use of biotechnology preserves and also enhances the uniqueness and diversity of the chemical composition of the grape raw material. We have established that after the four-year application of biotechnology the content of toxic compounds in grape raw material was reduced by 7%, and the concentration of biologically active substances increased in 1,5-2% times in comparison with the production of commercial plantations

VARIETY OF MICROORGANISMS GROUPS LIVING ON BERRIES OF GRAPES
DescriptionThe wide variety of microorganisms has been identified in many wine-making countries on the berries of grapes. These are yeasts of different families, forms and kinds, bacterium, mold fungi. In the article, we present the results of investigating species composition of microflora of berries of white and red types of grape, which grows in different economies of the Krasnodar region and the republic of Abkhaziya. The sowings onto the elective media were conducted for the development of entire spectrum of yeast. The grown colonies after preliminary microscoping were separated into the cultures and subjected to testing according to the culturalmorphological signs, being guided by determinants and benefits. It was established the specific variety of microflora on the surface of the berries of grapes of all investigated types, without dependence on the place of their growth. Obtained data showed that the group of yeast, which constantly is present in the complex of the epiphytic microorganisms of grapes of Saccharomyces, Pichia, Hansenula, Hanseniaspora was characteristic for all types of grapes in all investigated regions. The heterogeneity of the taxonometric composition of microflora is shown. Prevailed yeasts were of family Saccharomycetaceae, form Saccharomyces vini. A quantity of yeast of Saccharomyces vini decreases in a number of Myskhako-Caucasus-Fanagoriya, that as a whole will be coordinated with the climatic conditions. Only the type of Pinot nuar grapes had yeasts of Brettanomyces Dekkera. On the berries of Cabernets and Karaburnu we have discovered yeasts of Schisosaccharomyces acidodevoratus, causing acid-reduction. On the berries of the grapes, which grew in joint stock company APF “Fanagoriya” we haven’t revealed the presence of lactic acid bacteria Lactobacillus brevis and yeasts of the form of Schisosaccharomyces acidodevoratus. In the same farm the smallest quantity of yeastswreckers is noted, which we the forms of Pichia and Candida. In the microflora of Cabernets, Risling and, especially, Karaburnu grapes, we have found lactic acid bacteria Lactobacillus plantarum and Lactobacillus brevis. Lactobacillus plantarum. Among the bacteria the total quantity of coccic flora composes - 56 %, the rod-shaped - 44 %. Two types of active acetous bacteria are identified – Acetobacter aceti and Acetobacter xelinum. Especially high was their surface concentration on the berries of Kachich type of grapes

Description
The study was performed to genotype some commercial wine yeast strains using the assay of Interdelta genomic sequences. Experimental parameters of PCR to identify were optimized and optimal simplified method of DNA extraction from dried preparations of yeast cultures was define. Proven method showed a high level of resolution and can be used for the analysis of genetic diversity wine yeast in combination with SSR-markers

06.00.00 Agricultural sciences
DescriptionThe article reviews the results of the study of the influence of lignohumates of the grade "A" («LG- АМ», «LG-А super BIO», «LG-А super L») on the grape vines treatment of the Saperavi variety on the quality must and wine in the Anapо- Taman zone of the Krasnodar region. The technology of the cultivation of grapes on the experimental plot corresponded to the adopted in the JSC "Victory" of Temryuk District, and was accepted for keeping of fruit-bearing plantations area of non-covered viticulture. Agrobiological works were carried out at the optimum time and were of high quality type. Vines of the third year of life, embodied by the scheme in 3,0 x 1,5 m. The forming was a one-sided Guyot with a height of 60 cm in trunk. There was formed the same load by shoots and clusters on the shoots. The treatment of leaf surface bushes with the solutions of lignohumates were conducted twice: 1st - before flowering and 2 nd at the beginning of the formation of berries (20 days after the first one). The spraying was carried out in the early morning hours. The accounting for the grape harvest and sampling to determine the quality of must and wine (10 kg each variant) was conducted in September 20, 2012. Technological and physical-chemical analyzes were carried out in the shop micro winemaking and accredited testing laboratory of grape processing of the SSI NCZSRIHV of RAAS. Preparations "LG-B Bio", "LG-B Super Bio" and "LG-B Super A" as grape plant growth regulators have equal and stable effect

Description
The article investigates the possible pathways for the formation of crotonaldehyde in wine production in the result of the activity of wine yeast and lactic acid bacteria. It established that exposure to exhaust gases, noble rot, pathogens and pests on grape plant does not lead to the biosynthesis of crotonaldehyde in grape berry. The experimental data to identify probable pathways for the formation of crotonaldehyde during vinification has been presented. The effect of the test substance on the life of yeasts and lactic acid bacteria has been estimated

DescriptionIn the article there were presented the results of the researches on study of influence of different forms of the Stimokor stimulator of growth (Stimikor, Stimokor sweet and Stimokor Plus) as in a pure type as in a tank mixture with Nutrivant Plus water-soluble phosphorus-potassium fertilizer on agrobiological and technological indexes of Shardone grape. The most effect was obtained at the treatment of shrubs with Stimokor Sweet

STUDY OF AROMATIC CONTENT OF DIFFERENT BRANDIES MADE IN ARMENIA
06.00.00 Agricultural sciences
DescriptionBrandy alcohols from the grades of Muscat Berkatu, Kakhet and mixes of white grades of grapes became objects of researches. The content of some aromatic components of wine alcohols was investigated using the device of a gas-liquid chromatography Clarus-400 (with the ardent and ionization detector, a capillary column, 60 m x 0,32 mm, Elite-WAX ETR, gas-carrier-helium). Muscat alcohol according to the general content of aromatic substances (919,35 mg / 100 ml a.a.) was different from the other studied samples at the expense of the high content of ethyl acetate and izoamyl alcohol. As a result of the organoleptic analysis of a blend samples it was allocated a brandy blend with the following ratios of alcohol and wine - a blend alcohol – 74,37 %, liqueur wine – 25,63 % with strong muscat aroma and shades of taste
