This study has investigated the relationship between culture media, technique of concentrating and freeze drying conditions for the cells of Lactobacillus aci-dophilus. The study has demonstrated that milk whey tomato juice-enriched medium has the high-growth properties. This medium allows ensuring high freeze drying survival of Lactobacillus acidophilus
The article is devoted to the results of study of taxonomic situation and ecological features of venomous snake species spread in the territory of the Naxçıvan Autonomous republic. Materials for researches have been collected within 2011-2014 on different biotopes and landscapes according to altitudinal belts of the region. 4 venomous species like: Macrovipera lebetina, Montivipera raddei, Pelias renardi, Pelias dinniki and 2 semivenomous snake species like: Telescopus fallax and Malpolon monspessulanus were revealed in herpetofauna of the Autonomous Republic
The article presents data on the occurrence of pathological forms of trunk in hardwood species in suburban and green area of the city of Voronezh. Based on the studies, we have considered a pathological feature complemented and differentiated
The article defines the basic characteristics of the environmental performance of urban areas. There was offered the system of environmental performance indicators, covering the basic characteristics of the environmental performance. There was developed the algorithm and calculating methodology of composite index of the environmental performance of major cities in the context of rapid urbanization. There was conducted the approbation of the methodology according to the data of major cities which are the administrative centers of the Russian Federation for 2008, 2009 and 2011. There was carried out the rating of major Russian cities based on the composite index of the environmental performance
The questions of use duckweed as green vegetable are considered in article. The structure of types of duckweeds, their biological features, distribution in the world and in the territory of the Krasnodar region is shown. Possibility of their use as biotesters and
bioindicators of the water environment, as analytical system for the analysis is shown. Questions of use of duckweed in artificial conditions as well as requirements to the content of culture are considered
The features of introduction of trees, shrubs and herbaceous species in terms of the Krasnodar region and the south of the CIS are analyzed, the specificity of this process for deciduous and coniferous species, and grasses at their development in the spring and autumn periods, the allocation of forming niches generative organs, microsporogenesis, etc. are discussed. Opportunity to adapt different kinds of herbs and species of shrubs and trees, taking into account seasonal development with allocation of exotic species in the annual cycle of vegetation critical periods for the growing season Kuban has been considered. The results of the horizontal and vertical introduction in the study of the imported seeds and planting material of different species of trees, shrubs and grasses are discussed
Self-regulation of agricultural systems is based upon taking into account the interaction of their components released in variety of species and trophic relations; agricultural systems is diversified in towards a sustainable, productive and strategic development of the systems; one of the most promising areas of diversification of agricultural systems is considered to be an introduction to the practice of combining crops, known in agriculture for a long time, which shows us the nature. The most developed technology for creating combined crops is the practice of creating mixtures and the nature of the relationship between their different components
The accumulation features of radionuclides in the epitaphic pylaisiella moss (Pylaisia polyantha) in the territory of the city of Rostov-on-Don have been considered. The specific activities of 137Cs, 226Ra, 40K, and 232Th in the samples of moss, soils, and aerosol air have been compared. The capacity of Pylaisia polyantha to accumulate radionuclides has been estimated for four radionuclides (137Cs, 226Ra, 232Th, and 40K) with consideration for the background level. On the basis of radionuclide analysis, zones in the city of Rostov-on-Don with the highest accumulation coefficients of 137Cs, 226Ra, 40K, and 232Th were revealed. These were primarily the zones with both industrial and traffic loads and the motor transport zones
There have been examined the methods for estimating the degree of heavy metal contamination in soils. There have been revealed some discrepancies that concern estimation of soil contamination degree and calculation of consolidated figures for chemical elements contamination in soils stated in effective
normative documents. The formulas for estimation of summary soil contamination stated in normative documents reveals considerable discrepancies that do not let give an objective estimation of dangerous concentration of heavy metal. We offer estimation of concentration of several chemical elements not by summarizing their concentration but by estimating their excess in relation to rock or its concentration in soil taken as a background
