The article presents materials about selection and
optimization of the nutrient medium for cultivation
of Propionibacterium shermanii. We have shown a
high positive effect expressed in the intensive
growth of microorganisms of Propionibacterium
shermanii on optimized medium with the juice
from the tomatoes, as well as replacement of
glucose on corn extract, which allows concluding
that these components have a positive impact on
the accumulation of biomass of Propionibacterium
shermanii
Using of compound feeds in broiler feed additives of
plant resources, activates body's biological functions.
This increases productivity and gives an ability to
make environmentally friendly products. These local
plants feed additives contributing to enrich animal feed
with active ingredients include flour from nettle and
Caspian marine algae. This article is devoted to
studying the composition of nettle from the different
locations of growth in Dagestan Republic and also, to
determine the effectiveness of the use of nettle flour
individually and to how implement it with the
seaweeds flour in feeds of broiler chickens instead of
herbal flour. The studies showed that nettle from a
foothill zone in the flowering period exceeds slightly
the nettle from mountain zone on the content of dry
matter-1.19 % of protein-0.09 % and exchange energy
0.77 kcal/100g. Nettle meal from mountainous zone
also inferiors the foothills in the energy value to 6.81
kcal/100 g. The inclusion of 2% feed meal nettle, 3%
seaweed either alone or in combination of 2% instead
of+3% of alfalfa grass meal resulted increasing
broilers’ body weight 4,60-8,95% betterment survival
to2,8-5,70%, increasing muscle output at 0,56-2,54%
compared with the control group. The protein content
and the amount of essential amino acids in the thoracic
muscle in the test group was to 0.97-2.74%andto1,68-
2,11%, respectively, higher than the control. There was
a significant increasing iodine in thoracic muscles of
experimental groups 119,6-166,07% relative to
control. Based on the results of the research, it is
recommended to include 2% of feed meal nettle and
3% from algae instead of 4% grass meal of alfalfa to
improve the productivity and biological value of
broiler meat and 1 % of cereals
The article presents monitoring of the course and the
beginning of new invasions due to the intensification
of these processes in the basin of the Azov Sea of;
investigation of the influence of the alien species
upon the acceptor ecosystem. Methods. The material
was collected at the monitoring transect in the Don
River delta and in the surveys of the r/v “Professor
Panov” in the Taganrog Bay, Sea of Azov. Standard
hydrobiological methods of the data collection were
used. Results. Penetration of three polychaete species
was recorded; course of invasion of two of them was
traced. Impact upon the acceptor ecosystem was
researched. Preliminary species identifications using
morphological characters were carried out; sources
and the ways of the invasions are suggested.
Conclusions. Estuary zone of the Sea of Azov (the
Taganrog Bay) has a high invasion capacity. Of the
three species penetrated into the Sea of Azov basin in
2013-2015, one (Aracia sp.) naturalized successfully,
though didn’t affect much the ecosystem. On the
contrary, polychaetes of the genus Marenzelleria are
increasing rapidly their area; in two years, they
became dominant along the considerable part of the
water body. The invasion of Streblospio sp. is at its
very beginning at the time

analysis of phytocoenotic
The anthropogenic interference plays more and more increasing role in modern ecologic paradigm. Adjusting this role to the studied region, it is defined by the socio-economic conditions being formed in our country. The rate of construction in the resort zones of the Krasnodar region is sweepingly rising. In spite of the high therapeutic-recreational capacity of the region, this tendency is leading to the further worsening of the ecological situation. The strengthening of the ecological control in the terms of the present economic crisis is highly urgent when more and more Russians prefer native resorts for their rest and in the first turn - resorts of the Krasnodar region. The condition of the ambient air of some recreation zones of the Krasnodar region has been studied. Methods of atomic-absorbing chromatography and optical emissive spectrometry have been used. It has been shown that the differences in data are mainly determined by the different content of the air impurities depending on the probe selection place. According to the studied data, the ecologically purest places are Krasnaya Polyana and Goryachy Klyuch. Whereas, the content of atmospheric air pollutants in the central districts of the resort towns of Sochi and Goryachy Klyuch exceeds MAC. The comparison of the obtained data with the same data of the city of Krasnodar that had been obtained before allows making a conclusion about the favorable eco-hygienic state of the resort zones of the Krasnodar region. So our investigations authentically prove the existence of the significant differences in the ecological conditions of the city on the one hand and of the resort zones of the Krasnodar region on the other hand
The plant body cells must contain a certain
amount of water for a normal life. Water
deficiency in cultivated plants was due to using
herbicides used in intensive technologies of
cultivation of agricultural crops. The conditions
of the environment determine the sensitivity of
the plant to herbicide. Soil and climatic conditions
of winter wheat grown in the time of herbicide
treatment are important for the effectiveness of its
actions. It was found, that plants grown under
shade or high humidity are more sensitive to
herbicides than ones grown in bright sunlight and
in times of drought. During drought, and in the
open sunny spot, plant development is faster and
become more stable. On soils rich in humus, we
may grow less herbicide-resistant plants than in
soils poor in organic matter. Herbicides are
moved through the vascular system of plants with
nutrients and metabolic products, they cause
general poisoning as deformation of the stem and
leaves of the plants, growth inhibition, chlorosis,
fragility of leaves and stems, sterility, reducing
the amount of free to bound water, which is
particularly important for combating perennial
weeds that have strong and well-developed root
system. Monocots are able to immobilize the leaf
herbicides. Latency of herbicides and their
immobilization are carried out in various ways.
Elucidation of the physiological characteristics
that determine the resistance of plants to water
scarcity and the effects of the herbicides is the
most important task, the solution of which is not
only of great theoretical, but also has practical
significance
The article deals with hawthorn Dagestan. It is noted
that the more than 100 species are found 14 species in
Dagestan. The most common of them are studied as a
source of biologically active substances and nutrients,
and they can be used as food additives for various
purposes. The content of biologically active substances
and nutrients are defined. The high content of phenolic
substances in C. pentagyna Waldst. et Kit, which play
an important role in the formation of immunity and
possessing P-vitamin activity is defined. Amino acid
and fatty acid composition of the fruit of the hawthorn
Crataegus pentagyna Waldst. et Kit, as the most
valuable for using as food additives is defined by ionexchange
and gas-liquid chromatography. Sixteen
amino acids were identified and quantified in the
protein component of hawthorn fruit. The high content
of essential amino acids such as lysine, threonine,
valine, methionine, leucine, isoleucine, phenylalanine.
The amount of essential amino acids is 296.1 mg / 100
g. Chromatographic separation of fatty acid methyl
esters has enabled us to establish the presence of the
following fatty acids: palmitic, oleic, stearic, linoleic
and linolenic, including established the presence of
essential fatty acids - the family of alpha-linolenic acid
OMEGA -3 and linoleic acid family of OMEGA -6

This article presents information about the features of biotechnology as the driving force of scientific and technological progress. The national programs of the leading countries of the world, it is one of the priority sectors, reflecting the level of the socio-economic condition of the society. Biotechnology is now successfully solves such vital tasks as providing food, the establishment of effective medicaments, obtaining fuel based on renewable raw materials, maintaining ecological balance, conservation of biological resources of the Earth. The development of agriculture in modern conditions is impossible without agricultural biotechnology. It is directly related to viticulture. Choosing an object of an integrated system (embryos, apical meristem, axillary buds), it is possible to clone plants, i.e. produce plants identical to the original. If the same as the object to use isolated cells or protoplasts, in this case, there will most likely altered versions, creating diversity for the breeder. Genetic engineering – the science of younger, since the establishment of the first chimeric DNA molecule. The origin of genetic engineering is rooted in the development of molecular genetics, biochemistry. These technologies, undoubtedly progressive, but their biological safety is still insufficiently explored and is a danger to all life on Earth. The leading Western powers carried out strict control over the introduction of transgenic crop plants, as they are in agrocenosis new biological risks that may adversely affect the plants, animals and humans. In Russia, as in other countries, have already adopted the law “State regulation of genetic engineering”
