The important scientific direction of petrochemistry is manufacture of plasticizers, softeners, vulcanizing agents, fillers on the basis of industrial wastes. This allows to expand the raw-material base, use heavy stocks of refinery wastes, reduce environmental pressure on the nature and solve the problem of manufacture of importsubstituting softeners for the rubber-processing industry of Kazakhstan. Besides, the feature of Kazakhstan petroleum crude oils is high concentration of sulfur compounds, in consequence of which much wastes are formed. Optimization of developed rubber compounds for manufacture of a wear-resistant chafer strip of passenger car tires was carried out by serial analysis of influence of content of each of the components separately (sulfur and oil sludge) at the fixed amount of other ingredients on the rubber properties. With a view to identify optimal amount of organic share of the oil sludge in the content of rubber compounds, rubber compounds with different content of organic share of the oil sludge were gained. Plasticizers and softeners were substituted to the organic share of the oil sludge. Also polymeric and colloidal sulfur mixture of Tengiz field was used as a vulcanizing agent in the receipts of rubber compounds. The results of comprehensive tests showed replaceability of traditionally used in the rubber compounds softeners to the organic share of the oil sludge and use of Tengiz sulfur as a vulcanizing agent. © National Academy of Sciences of the Republic of Kazakhstan, 2016.

The present article justifies the necessity of improving the food security planning within the framework of implementing the millennium development goals. In this regard, the study develops a brand new approach in the theory of methodology for assessing and monitoring the global food security, aimed at forecasting quantitative scenarios of its development. A distinctive advantage of this approach is the ability to forecast optimistic, pessimistic and realistic scenarios for provision of food security levels regarding certain groups of countries depending on their economic development. This approach utilizes subjectivity in the process of monitoring the provision of food security levels and contributes to optimizing the ways to increasing it in conditions of uncertainty. © 2016 Orazaly Sabden and Abdumalik Ashirov.

Research material source is taken in Karasai district of the Almaty region's Kaynar settlement's vegetable warehouse. Here is a list of the fungi's species which affect the quality of the vegetables and belongs to the fungi species such as Alternaria radicina, Fusarium avenaceum, Penicillium cyclopium, Sclerotinia sclerotiorum relative found in the types of groups such as Alternaria, Fusarium, Penicillium and Sclerotinia. Morphological criteria were defined as a result of this experimental research. Also their Damaging properties and stability to fungicides were investigated. Currently, agriculture's one of the main directions is a stable supply of agricultural products to population. According to the UN Food and Agriculture Organization's census the harmful organisms reduce agricultural products by 30 percent annually. There are the most common types of diseases caused by fungi widely spread among these harmful products. Nowadays clarification and the establishment of strategic measures to combat the biological characteristics of disease-causing fungi are found as the key issues.

Microencapsulation of vitamin E directly from oil-in-water (o/w) emulsions was carried out by means of a novel practically relevant approach. For the first time, a preformed polyelectrolyte-surfactant complex (sodium polystyrene sulfonate/dodecyl trimethyl ammonium bromide) was simultaneously used as an electrosteric emulsion stabilizer and as a charged precursor for the following build up of microcapsules. Subsequently, a layer-by-layer technique was applied to emulsions leading to the formation of core-shell microcapsules with oily cores and polyelectrolyte shells. The effect of the complexes on the process of emulsion formation and on the stability and characteristics of the resulting emulsions was investigated by measurements of dynamic and equilibrium interfacial tension, size distribution (DLS) and interfacial charge (zeta-potential). The resulting microcapsules were characterized by confocal laser scanning microscopy (CLSM), Cryo-SEM, size distribution and zeta-potential measurements on each stage of the shell assembly. The release kinetics of vitamin E was monitored during the consecutive steps of the encapsulation procedure using UV-vis spectroscopy and showed the progressive enhancement of sustainability.The developed approach may be promising for the practical use in the cosmetic and food industry. © 2015 Elsevier B.V.

As a consequence of development of combined method of purification and extraction of pectolytic enzyme, we have produced the enzyme with higher polygalacturonase (PGA) activity with a sufficiently high yield of the final product. The method is based on consecutive removal of individual groups of inactive impurities from enzyme solutions by means of activated charcoal and anion-exchange resin. Application of hydroxyapatite makes it possible to achieve activation of pectinases by removal of low molecular proteins. The absence of pectins and carbohydrates facilitates its usage in winemaking for clarification of superior wine grads and removal of wine stone composed of pectin substances of grape juice. © 2016.

It is recognized that in case of full compliance with sanitary requirements, one can get from the bulls up to 72-74% of ejaculates, containing not more than 2,000 microbial cells per 1 ml, and from boars - 67-69% of ejaculates with microbial cells in amount of maximum 5,000 per 1 ml of semen. Most frequently ejaculates contain pathogens, opportunistic cells (blue pus bacillus), streptococci, micrococcaceae, saprophytes, olm, and fungi. The sensitivity of the semen microflora was tested to 24 antibiotics; among them 15 antibiotics were selected to be tested in terms of harmlessness to semen. Based on the research conducted we have developed a new antibacterial complex for sanitation of breeder semen that can be used for decontamination of ejaculates microflora providing at the same time increased holding period of spermatozoa, as well as birth of healthy offspring. A new complex is composed of the following ingredients (per 100 ml of the extender): cefotaxime - 10 mg, gentamicin - 8 mg, and oleandomycin phosphate - 60 mg. Cefotaxime and gentamicin have a different spectrum of antimicrobial action. An important property of both drugs is their chemical and antimicrobial compatibility. Application of the developed antibacterial complex reduces microbial contamination of semen by 6.4-8.3 times that indicates synergistic action of the ingredients against the semen microflora. Sanitation of breeder semen by means of novel antibacterial complex contributes to better seminal sowing. Breeding efficiency of pedigree stock, inseminated with semen, treated by new antibacterial complex, was 11.7-12.9% higher than that in control.
