Description
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

MULTI-LAYER COMPOST AS AN IMPORTANT SOURCE OF ENRICHMENT OF SOIL NUTRI-ENTS
DescriptionMulticomponent compost represents a good environment for a significant number of species of living organisms and populations which produce enzymes, vitamins and other active substances. Chemical and physical properties of complicated composts are heterogeneous and polydisperse interim systems, and on the gene pool of living organisms are a rich comprehensive substratum. The heterogeneity of complicated composts of characterized by a very wide range of organisms which using animal waste and isolating of germinating seeds and spores of higher and lower plants

Description
The article gives the description and the algorithm of the simulation model SMDS "Potok" 1.0, designed to calculate the parameters of distribution and sedimentation of technological alluviums in watercourses. The relevance of the simulation model is due to the need to determine the integral indicators (the volume of water flowing through the areas of the plume with a predetermined suspension concentration, the average layer of the silt, the specific density of the bottom silt in the calculated zone) when calculating the harm to water biological resources from the implementation of various economic activities in accordance with the methodology of calculation of damage caused to water biological resources approved by the order of the Federal Agency for Fisheries No. 1166 of 25.11.2011. Usage of the simulation model of SMDS "Potok" 1.0 will increase the reliability of calculations in determining the damage to water biological resources, as well as bring the calculations of parameters of distribution and sedimentation of technological alluviums in watercourses in accordance with the current regulatory legal acts of the Federal Agency for Fisheries
