One of the ways to save rare species of plants is to create models of natural communities on the grounds of the botanical gardens. In the Botanical Garden of Kuban State University we have created the model of forest communities with the participation of rare and endangered species, and we are still working on creating models of herbaceous communities. We have introduced 18 species of plants of the flora of the Krasnodar region in the forest community and more than 30 species in herbaceous community
In the article we investigated the effect of the bacterial metabolites compositions (Aktoflor and Patogen) on antagonistic activity of L.acidophilus D â„– 75. It was shown the both compositions stimulate integrated antagonistic activity of L.acidophilus D â„– 75 by inducing the synthesis of the bacteriocin and decreasing the proportion of low active clones in the population. We have also shown the advantage of probiotic bacteria metabolites (Aktoflor). The results can be used to enhance the probiotic potential of the bacterial preparations
The article proposes a method for landscape area analysis, which consists of four stages. Technique is proposed as a tool for the practical application of pre-project research materials in the design solutions for landscape areas planning and organization
The article reflects influences of soil conditions on growing types of wood vegetation. The carried-out chemical analyses show quantity of chemical elements which have to arrive to the soil with tree waste, and also acidity of the soil
The research of the territory adjacent to Novocherkassk state district power station, for the content of polycyclic aromatic hydrocarbons (on an example of benzo(a)pyrene) is presented. The benzo(a)pyrene content in soils has been determined with a method of subcritical water extraction. The content of benzo(a)pyrene in soils of the territory adjacent to Novocherkassk state district power station has been estimated. It is shown, that contents of benzo(a)pyrene excess over maximum permissible concentration in soils of five-kilometer zone around the companies
The article discusses the features of the pathogenesis of micromycetes Gibellina cerealis Pass. in vitro
In the article we have studied the technology of obtaining a biomass of oil oxidizing microorganisms in a nutrient medium containing vegetable oil as the sole source of carbon and energy. In vitro and in soil experiment we have confirmed the effectiveness of the resulting biomass at work on bioremediation of oil contaminated sites. It is shown that the use of vegetable oil during culturing allows obtaining the same amount of biomass and carbohydrate raw materials, but the efficiency of its use is 20% higher, in average
The article reflects the influences of the biogeohorizons on structure of oak plantings. It also shows biomass model of oak trees and its satellites in the studied areas
In the article volumes of genera, species of Coleoptera, Elateridae of the Republic of Dagestan are given
In this article we have carried out a comparative study of hydro-carbon-oxidizing activity of S-and R-morphological types of oil oxidizing Actinobacteria from the collection of Kuban State University. Signifi-cant differences observed in parameters of growth between S- and R-forms of oil oxidizing Actinobacte-ria. In S-forms it is higher than the maximum specific growth rate, which is typical for a wide range of hy-drocarbon degradation and a high degree of degrada-tion of pollutants. In experiments with the use of oil as a substrate and heavy oil S-forms, Actinobacteria quickly adapted to the environmental conditions
