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
This review is devoted to the 60 anniversary of the
winter wheat variety (Triticum aestivum L.)
Bezostaya 1 – a masterpiece of world selection. This
variety played a great role in increasing total grain
yields in the Kuban Region. It also was an important
gene source for Russian and world breeding. This
variety has initiated and was for many years a party
to research molecular biological mechanisms of
wheat frost resistance formation. The article
summarizes data about the peculiarities of
functioning of protein-synthesizing system it sprouts
(coleoptilies) under the influence of hardening
temperature (4oC): translational activity in vitro,
poliribosomts, degree of polyadenilation and stability
of total mRNA and specific mRNA translational
elongation factor α subunit 1 (eEF-1 α). The in vitro
(ommp) system, which adequately characterizes the
relative mRNA stability in vivo was used for these
measurements. The effects of cooling and light on
mRNA stability were shown to be cultivar-specific.
The hardiness of winter wheat has a positive
relationship with the amount of RNA and DNA, and
a negative correlation with the amount of magnesium
cations in mature grain that can serve as a simple
marker of frost resistance. The main feature of the
variety Bezostaya 1 is high content of magnesium
ions (Mg++) in RNA molecules and relatively low
variation of Mg++-depending molecularphysiological
responses for different environmental
conditions. The knowledge gained in the study of
variety of Bezostaya 1 contributes to the
understanding of molecular biological processes that
underlie the selection and determining its future
success
The article studies the influence of polymeric in
the form of formers and growth regulators on the
growth and development of rice plants when
grown in saline conditions. We controlled the effect
of salinity on grows regulators and vigor, seed
germination, root and shoot weight, the content of
photosynthetic pigments parameters, induction
curves of delayed fluorescence, the indicators of
structure of harvest, grain yield. It was found, that
pre-sowing seed soaking in solutions of polymer
grows regulators has a stimulating effect on the
growth and development of rice plants in the early
stages: we significantly increased germination and
emergence, dry weight of root and shoot compared
to control. At different stages of ontogeny
rice, the absolute content of pigments in the leaves
and the relationship between the individual variants
change. The absolute content of pigments in
leaves and their relationship between experiences
at different stages of ontogeny change. In the period
of intensive vegetative growth from seedling
stage the content of total chlorophyll is maximum,
and by the end of the growing season it decreases.
It can be assumed that the salinity of the substrate
significantly reduces the productivity of photosynthesis
in young plants, possibly due to imbalance
of ions in the cell, the older it gets – the weaker
the phenomenon is and even becomes reversed.
The second maximum IR ZF increases during the
growing season from germination to flowering,
then decreases to the beginning of ripening in all
embodiments. The same dynamics is characteristic
of the magnitude of the proton gradient in the
membranes of chloroplasts tylakoids. Salt protection
effect of growth regulators on grain yield is
significant on both backgrounds of mineral nutrition
Humpback whitefish - Coregonus lavaretus pidschian
(Gmelin, 1788), is spread in Siberia, in the Kara,
Laptev and East Siberian seas and in the lakes of the
Arctic and Subarctic. Objective: To assess the status of
fish in the waters of Yakutia, to make ecological
forecasts and determine the possibility and prospect of
economic use of whitefish, as a fish-breeding material
in the present conditions. Methods: The analysis was
carried out on the fresh material as described
I.Pravdina (1966), taking into account the
recommendations of Y. Reshetnikov (1980).
Collection and processing of materials were carried out
in 1969-2015 by standard methods. Results. Reaching
sexual maturity at the sixth (in weight - the eighth and
ninth) year of life, whitefish begin to move to the main
breeding groundsin the early fall. Absolute fecundity
of eggs 2500-140000. Spawning is common in late
September-early October. The food spectrum usually
consists of the following objects: chironomid larvae,
plants, mollusks, fish eggs and copepods. By the
nature of power - benthophage, but often becomes
planktonic organisms. Conclusions. Important food
fish, but its reserves significantly reducedunder the
influence of anthropogenic factors in recent years. The
catch of whitefish can be increased as a result of the
development of aquaculture
Numerous revealed negative impacts of the diamond
industry and Vilyuiskaya HPP on the aquatic
environment and biological objects are more expressed
in the change of the hydrochemical regime in water
basin of Viluy and as its consequence - in violation of
the structural and functional nature of the components
of aquatic biota; in the change of he average biomass
and abundance of planktonic populations
(phytoplankton and zooplankton) and benthic
organisms, and in general - in the change of the flow
energy in an aquatic ecosystem
In the work, we present the results of the investigation
of acute toxicity of bio humates obtained by the method
vermicultivation on laboratory animals. In the diets
of farm animals and Pets to fill in the missing nutrients
in the past years, we had an extensive use of various
feed additives. Among them, mineral (macro - and
micronutrients), protein and fat supplements, vitamins,
biostimulants, complex natural compounds (sapropel,
peat), synthetic products (enzymes, hormones, antibiotics,
adaptogens, antioxidants). The search for new
ways of improvement and increase of efficiency of
agricultural animals using feed additives with high
demands on ecology of meat and dairy foods naturally
led to increased studies on the use in livestock farming
of water-soluble alkaline salts of natural humic acids -
humates. Their environmental safety and the unique
ability to improve metabolism and increase energy
cells very positively manifested in living organisms.
Numerous studies Russian and foreign scientists installed
a high efficiency natural humates as biostimulators
and immunomodulators in animal husbandry and
veterinary medicine. Accumulated extensive experimental
material, proving that the use of humates leads
to faster growth of animals, reducing morbidity and
mortality, increase the body's resistance to toxins in
feed and resistance to adverse environmental conditions.
Improving with the help of humates ecological
purity of the ecosystems "water — soil — plant", as
well as the health of birds, animals and fish will ultimately
lead to strengthen health and to prolong human
life as a consumer of agricultural products. Currently,
the livestock market is intensively increasing the humates
produced in Russia and abroad from brown coal,
peat, sapropel. A special place among them has been
occupied by the newest formulations because of a
unique combination of safety, efficiency, and value,
which, thanks to its amazing properties to increase energy cells, stimulate vital processes and to enhance
the beneficial effects of other substances called energine.
They are harmless to animals and humans; do not
have allergologie, anaphylactogenic, teratogenic, embryotoxic
and carcinogenic properties when used in
recommended doses. This allows you to create on their
basis organic natural feed additives and veterinary
medicines for agricultural animals, birds, fish, fur animals
and Pets, and preventive and therapeutic drugs
for humans
Pike inhabits almost all the rivers of the Yakutia
system. It is more widespread in the lakes of YanoIndigirka
and Kolyma lowlands. Objective: To provide
a modern assessment of fish in the main model
reservoirs, create an ecological prognosis and the
possibility of their use in modern conditions. Methods.
The material was collected in the conditions of
anthropogenic pollution. Full general biological
analysis was conducted for the fish. Cruise studies
were conducted covering the northern territories - r.
Anabar, Olenek, Lena, Yana, Indigirka, Kolyma and
Chrome, as well as Vilyuy Dam, from 1969 to 2016.
We used the standard ichthyologic methods of
selection and processing of the collected material.
Results. Because of climate warming, there were
reported pike approaches in the lower reaches of the
river Lena, Yana and Kolyma. Maximum dimensions
were noted earlier in the lower reaches of the river
Lena, where the maximum weight of pike was 18 kg.
The fecundity of 16-211 thousand eggs. It was
revealed, that the catch was better for young pike.
Conclusions. Stocks of pike are in satisfactory
condition, and its reserves are proposed to be
increased, at the expense of unused areas (lakes
Kolymo- Indigirka lowland) up to 220 m. It is
proposed as a fish-breeding facility in Yakutia
reservoirs
