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
МF-4SК membrane-based microbial fuel cell (MFC) was used for an anaerobic utilization of organic com-pounds of various liquid wastes. During incubation in short circuit mode, decreasing of the COD value on range 30-87 % depending on the type of wastes was detected. The dependence of the microbial fuel cell output power on the value of the external load was determined by a number of structural characteristics of MFC
The article considers turban cucumber forms, we have also described the origin of this characteristic, briefly overviewed turban forms in species of the family of Cucurbitaceae. We have given the agro-botanical iconography of this trait in pumpkin cultures for cucumis. In Europe, China and America turbanoformis cucumber forms are used as a vegetable, there are some varieties. It is shown that turbanoformis forms are found in the fruit of the cucumber with hermaphrodite flower, polunina ovaries, short or shareplace the melon, and also in forms with the ongoing evolutionary process
The data of the morphological, cultural, physiological and biochemical characterization of α-glucosidase inhibitor producer, isolated from soil sample by selective methodic is presented in this work. It is shown that on the set of listed attributes the culture can
be referred to Kitasatoa genus. The 9th edition of “Key to the bacteria,” Bergey, Kitasatoa genus moved to a group of “Streptomyces and related genera” and transformed into the Streptomyces genus. In this case, strain 839 was named Streptomyces species, it was given the number 1328-D
Complicated compost with organic and mineral components, has a serious impact on the physical, chemical and biological properties of topsoil significantly modifies its cycles of elements and substances; with the Carboniferous and up to now it has been established the supremacy of the recovery processes in landscapes as compared to oxidation processes through the introduction of complicated compost in their stabilizing factors
This article summarizes the results of the study of physical, chemical and biological characteristics of mineral waste; it analyzes the specific features of its behavior when applied to the soil in pure form and in complex compost; the possibility of using some of them as an ameliorant for improving the fertility of soil common in the steppe zone of the region
The article considers the multiple use of lagenaria or bottle gourd in different countries of the world. It presents the information of the different types of lagenaria that in each country have their own purposes. Attention is paid to the origin of culture, in this
context, considered a variety of the use of culture. A distinctive feature of the culture is that lagenaria is one of the ancient plants that were cultivated by mankind as functional and decorative purposes. We have analyzed lagenaria using on the territory of our country. Total analysis with iconic images of plants allowed us to evaluate new opportunities in the use of
culture. In the work we have applied methods of analysis, synthesis and descriptive method
Ecological niche acts as an important evolutionary function of living organisms in the ecosystem and determines its properties, which are caused by the nutrient requirements, mobility, ability to reproduction, biochemical features, structural features limits tolerance to environmental conditions, opportunities performing certain actions in the specific biocenosis; in the process of divergence (species, their internal and external properties and abiotic characteristics) features of ecological niches are changed , there are new kinds of living organisms and, of course, the formation of new ecological niches
BARLEY LEAF RUST (PUCCINIA HORDEI OTTH. PATHOGEN) IN THE NORTH CAUCASUS: SPREAD AND RASE COMPOSITION
The spread of barley dwarf rust pathogen has been studied in five agro-climatic zones of North Caucasus in 2012-2013. The race composition of the North Caucasian pathogen population was identified
With biotechnology development, working out and introduction of the new technologies focused on an intensification of a complex of difficult biochemical transformations which proceed in meat raw materials by manufacture smoked sausages became possible.
One of such ways is introduction of starting cultures in a compounding of sausages. In this article we have presented the researches of perspective microbial strain and the choice of the strain for creation of starting cultures
