The isolation of E.coli phages from samples of natural
and waste water obtained during expeditions in the
different regions of Russian Federation was carried
out. The obtained phages (286 isolates) were tested for
their ability to lyse the pathogenic strains of E. coli –
pathogenic agents of pig colibacteriosis in Krasnodar
region. The study was conducted of their ability to
phage transduction, the molecular-genetic
characterization and biotechnological parameters of
selected bacteriophages. For first experimental design
of veterinary drugs was selected 5 coliphages having no ability of plasmids transduction. It has been shown
that all the investigated phages are representatives of
T4-type phages of family Myoviridae. The reported
study was partially supported by RFBR, research
projects No. 08-04-99111, 09-04-10132, 16-44-

The genetic variability study of Pinus sylvestris trees appurtenant to different selection categories in the plus stand is carried out with ISSR markers. A total of 178 loci were amplified by 6 ISSR – primers and 168 of them were polymorphic. It is detected that the genetic distance between the trees appurtenant to difference selection categories varies from 0,038 to 0,082. Genetic variation parameters of the Pinus sylvestris plus stand are calculated. Shannon’s index (I) was 0,4303, Nei’s gene diversity (H) was 0,2735 and Effective number of alleles (Ne) was 1.4268
The variety Krimbas is a hybrid,
was gotten by Panteley Zamanidi in Greece and Troshin Leonid in 2001 year by crossing of the varieties Aigeorgitiko and Muscat aleksandriisky.
It is got into the group of black sea grape varieties (convar. pontica subconvar. balcanica Negr.). The production period is 146-155 days. The growth of shoots is higher.
The average mass of cluster is 300 g.
It has higher resistance to frost, drought and fungal diseases compare with Muscat Vitis vinifera L. varieties.
The leave is middle, black-green, five lobes, deep dissected, the bubbles on the upper side of leaves surface is low. The upper and bottom cuttings are closed with gleams. The form of cut of leave with low elliptic gleam, the length of petiole is middle.
The flower is hemofradit. The ovary is low conical. The pollen is fertile.
The cluster is middle or round, conical, middle density. The berry is middle side, oval, black-blue color. The skin is thick. The pulp is juicy, with Muscat after taste, the juicy is not colored.
The sugariness of juice is very higher: the berries after overripe faded, then overraisines till 30% from the berry.
The quantity of seeds in berry one, rare two. The seed of middle length, brown color, piriform, with shot beak. There are sometimes berries with not advanced seeds.
The variety used for preparing dry pink and red wines of perfect grade, so and dries higher quality desert and liker wines; it is used for preparing juice, compotes and jam. The risen got of good quality with soft Muscat after taste.
The article considers the multiple use of lagenaria or bottle gourd in different countries of the world. It presents the information of the different types of lagenaria that in each country have their own purposes. Attention is paid to the origin of culture, in this
context, considered a variety of the use of culture. A distinctive feature of the culture is that lagenaria is one of the ancient plants that were cultivated by mankind as functional and decorative purposes. We have analyzed lagenaria using on the territory of our country. Total analysis with iconic images of plants allowed us to evaluate new opportunities in the use of
culture. In the work we have applied methods of analysis, synthesis and descriptive method
Novoafonskaya cave is located in Abkhazia. It is
equipped for visits in 1975. The cave has permanently
installed lighting. In caves with artificial lighting, a
vegetation of cyanobacteria and algae, bryophytes and
ferns can be found around lamps. The development of
lampenflora is a typical problem for cave management.
We have identified 69 species of phototrophs in
Novoafonskaya cave: Magnoliophyta 2 species,
Pteridophyta 6 species, Bryophyta 11 species,
Cyanobacteria 34 species, Bacillariophyta 9 species,
Ochrophyta 2 species, Chlorophyta 5 species. The
article considers main habitat of lampenflora and gives
their characteristics. We have also revealed
predominance of cyanobacteria in the cave
The article proposes a method for landscape area analysis, which consists of four stages. Technique is proposed as a tool for the practical application of pre-project research materials in the design solutions for landscape areas planning and organization
Products, received from hips (fruits of wild roses), are profit a high consumer demand, that dictate solutions, which connected with technology of improvement natural dense bushes and creating artificial planting the most valuable in economic relation forms. In connection with it different characters of allocation of wild rose’s bushes is revealed by indicator of size of hips
Leaf morphometry of Kuban wild-growing grape
liana has not been studied yet and there is no
evidence of straight subspecies representatives
location of Vitis vinifera silvestris Gmel. on the
Kuban land. Though there have been suppositions
about it in science since long ago [5]. With
morphometric taxonomy appearance there was
necessity of exact focusing on modern state of
genotypic grape variety and biological leaf
polymorphism for link identification silvestris –
silvesatis - sativa
The mathematical model of soil stability to heavy metals contamination is proposed. The Lower Don soils contamination with Cu, Pb and Zn was calculated
The article considers the issues of distribution of Luffy, the properties of its fruit, its cultivation technology. It also discusses the features of biological development and farming cultivation. Based on the analysis of the image, it shows the main countries of
its industrial production: China, India, Vietnam, Japan. Attention is paid to the dissemination of Luffy in our country, the directions of breeding research have been substantiated
