Abstract Clostridium butyricum is a spore-forming probiotic existing in the intestines of humans and animals which can promote the enhancement of beneficial bacteria and maintain intestinal microecological balance. However, it is difficult to improve the production level of C. butyricum by conventional fermentation process. In this study, a co-fermentation process of C. butyricum DL-1 and Bacillus coagulans ZC2-1 was established to improve the viable counts and spore yield of C. butyricum, and the formula of coculture medium was optimized by flask fermentation. The results showed that the optimum medium composition is bran 10 g/L, corn steep powder 15 g/L, peptone 15 g/L, K2HPO4 1 g/L and MnSO4 0.5 g/L. Cultured stationarily in the optimal medium for 36 h, the number of viable bacteria of C. butyricum DL-1 reached 1.5×108 CFU/mL and the spore forming rate was 92.6%. The results revealed an economical and effective medium composition for the coculture of C. butyricum and B. coagulans. The co-fermentation process established in this study provides a new fermentation mode for the industrial production of other absolute anerobic bacteria.

The article considers the aspects of increasing the competitiveness of an agricultural enterprise in modern conditions with the use of innovative management methods. Ensuring the country's food security is impossible without intensive cultivation of agricultural crops, based on the achievements of scientific and technological progress. The solution of this problem requires a large number of investments in the conditions of limited land resources and the instability of agro-industrial production.

The article discusses synthesis method of sex pheromones as low-molecular weight bio regulators, as well as their application efficiency in combating pests of the agricultural crops. According to the conducted investigations, the sex pheromones are non-toxic, do not cause any environmental pollution; they are also ecologically safe and economically efficient. Hence, in case of industrial production they can be widely used in agriculture - forestry, greenhouse and other farms.

the formation of large-scale high-tech specialized areas for the production of certain types of agricultural products is an objective process that is inherent only in commodity production. He is getting stronger with the development of productive forces and market relations, oc-curs under the influence of various factors, among which should be noted the compliance of natural conditions and features of cultivation of agricultural crops

The government of Kazakhstan is currently developing strategies and policies to stimulate milk production at an industrial production level to increase milk processing capacity. We use and expand the reasoned action approach as a framework to study the factors underlying the rural household’s motivation to participate in a governmental programme aimed at increasing rural cooperative production in Kazakhstan to increase milk production using primary data acquired from 181 randomly selected dairy households in the Akmola region of Kazakhstan. We account for the rural household’s psychological factors and socio-demographic characteristics along with the household’s risk attitudes, production structure, level of information about the government support programme and cooperatives, cultural aspects as well as the household’s proximity to the main market. A bivariate probit model is used to jointly estimate the impact of these factors on the rural household’s intention to join and create a cooperative. The results show that rural households which hold positive views towards cooperatives, have a relatively high production capacity, are aware/know of cooperatives, and do not have a dairy business as a source of household income are relatively keen to participate in collective actions. Perceived social norms and household risk attitudes also play a significant role in the rural household’s intention to participate in collective actions. Finally, gender and nationality are found to be positively associated with joining and creating a cooperative, while higher educated rural households are found to be less motivated to participate in the programme. In order to stimulate milk production at an industrial production level through a policy that encourages collective action, we recommend a policy that (a) supports rural households which have the capacity to produce and are in need; (b) is attractive to rural households which consider dairy as a source of income; and (c) is well disseminated and well explained to the targeted rural households.

Calculation of the aggregated "consensus" industrial production index has made it possible to date cyclical turning points and to measure the depth and length of the main industrial recessions in Russian Empire/USSR/Russia for the last century and a half. The most important causes of all these recessions are described. The cyclical volatility of Soviet/Russian industry is compared to that of American one.
