Sustainable development of agricultural enterprises crucially linked with the revival of investment and innovation process, without which it is impossible to restore productive capacity and economic growth. The basis of innovative changes in the economic activity of agricultural enterprises should become an integral concept of strategic transformation.

The 1-aminocyclopropane-1-carboxylate (ACC) deaminases, the key enzymes of degradation of the precursor of the phytohormone ethylene, and have been poorly studied despite their great importance for plant-bacterial interactions. Last time there is an opinion, H₂S takes important part in growth and development regulation of plants and stress answer. However, molecular mechanisms of H₂S action in plants are poorly understood, although it is clear that key enzymes for hydrogen sulfide biosynthesis are D-cysteindesulfhydrases. Studied the spread of gene acdS and dcyD, which code key enzymes for increasing plants stability by bacteria, ACC-deaminase and D-cysteinesulfohydrase of aerobic methylotrophs genus Methylobacterium. And characterized ACC-deaminase from facultative methylotrophic actinomycetes Amycolatopsis methanolica 239. In result of research there were detected and sequenced genes acdS from Methylobacterium goesingense DSM21331 and dcyD from Methylobacterium trifolii DSM23632 and Methylobacterium gnaphalii 23e DSM 24027, and also constructed phylogenetic tree which was based on the translated amino acid sequence of proteins. For the first time ACC-deaminase was cloned and characterized from bacteria of phyllum Actinobcteria A.methanolica 239, what says about her supposed ability to be in simbiosys with plants. The enzyme had K_m 1.7 ± 0.2 mM. The k_cat values were 5,1±0,2 min^-1. AcdS is homotetramer with a molecular mass of 144 kDa. The purified enzyme displayed the maximum activity at 60 °C and pH 8.5. Results can be used for next researches of metabolic foundations plant-bacterial interactions.

Morphological and biochemical study of lambs of different ages Buryat tonkorunnoj breeds. Influence of colostrum on the immune system of the Lambs, and changes in protein fractions of blood serum with an age indicator.

The results of studies on the reproductive qualities of mature boars of breeds: Large white, Landrace, Ukrainian meat, intrabreed type of pig breeds Duroc Ukrainian selection "Steppe" and breed Pietrain depending on technology of management and availability of exercise. It was established experimentally that the provision of the boars of the free choice of exercise helps improve the overall performance of sperm, increasing thus the fertilizing ability. The duration of the period of sexual activity of boars when free ranging management decreased on average by 0.3 minutes (P>0,99), and for boars breed Pietrain the presence of exercise increased the duration of the period of sexual activity by 0.2 minutes (P>0,95). The presence of exercise has a positive effect on the manifestation of reflex erection and copulation.

The paper presents the results of the study into the influence of a pesticide of the state of certain cell and immunity humoral chains

In this article such concept as food security which many authors is understood as uninterrupted providing all segments of the population with qualitative food of mainly own production not below the accepted physiological norms is considered. Also various criteria and indicators of its assessment come to light. Along with domestic researches in this area, the attention is paid to world practice in general.

The use of silver-rich mineral sorbent as a dietary Supplement increases the nutritional and biological value of bakery products, gives them antibacterial properties that allows their use in therapeutic-prophylactic nutrition, prolongs the freshness of bread and expands the range of treatment-and-prophylactic bakery products.

Current problems in the industrial livestock and poultry is the prevention of associated bacteria and viruses), avoiding their drift into an industrial zone, the use of natural ecological protection of chickens, alternative antibiotics and other means of chemical nature. One such tool could be allogeneic immune serum produced at the place of raw material (blood) on the principles of non-waste technology. Multiplicity aerosol treatment: day-old chicks (at the time of landing) and at the first change in the diet (5 days old).

The work is dedicated to justifying the need for the formation of policy of import substitution as a factor in ensuring food security in the introduction of the food embargo. Based on the study concludes that the integration of the most effective form of partnership for sustainable development of agriculture.

One of the main factors determining the effectiveness of innovative development and agro-industrial complex is a technical potential. The analysis of the state of technical capacity in the agricultural komples in the whole country, the Siberian Federal District and the Novosibirsk region, the availability of equipment and provision of its various levels of the agro-industrial complex. Shows comparative data volumes support measures and technical sphere of agriculture in different countries. On the example of Novosibirsk area shows the need for targeted technical modernization of agriculture.

The article analyzes the current problems and reveals the problems of land resources related to various causes in a market economic system. Assesses the status and use of land resources at the present stage as an important factor in the economic development of the state. We offer an further ways of solving the problems under consideration, taking into account market requirements.

The article describes the factors under the combined of which is a formation a efficiency of cattle breeding production in the agricultural enterprises.

The article is the result of historical and comparative study of the food consumption of the population. Comparison of food consumption carried out between the people who lived in 1912-1913 in major cities and towns of the Russian Empire with a population of over 50 thousand people and the general population of the Russian Federation in 2000-2006 and 2008-2012
