Brewer?s spent yeast is a byproduct containing high amounts of nitrogen, vitamins and immunogen compounds such as ?-glucans. Several uses of spent yeast were described, but the phytostimmulatory potential was not previously tested. In the present paper, the effects of spent brewery yeast on rye microgreen growth and composition and the potential use as an elicitor is assessed. Rye microgreens elicited with spent yeast presented improved germination, especially after 4 days of cultivation. Increased plantlet length...

Natural compounds and products are increasingly demanded by the pharmaceutical and cosmetics industries as safer and user friendly alternatives to synthetic variants. Young wheat plantlets, known as wheatgrass, are a valuable source of minerals, vitamins and chlorophyll pigments and the biosynthesis of such compounds may be influenced by the cultivation conditions. The present study focuses onto the chemical profile, mineral and chlorophyll content of cultivated wheatgrass using two different types of water (sprin...

An accurate simulation of snowmelt infiltration rates for an area of Bucegi Mountains, during spring thaw, has been made using the snow routine of HYDRUS- 1D. The model is based on coupled flow and heat transport in the vadose zone. The snowmelt routine is based on degree day concept. As boundary conditions are used, surface water and heat fluxes can be calculated from the energy balance equation. The variables of the surface energy balance equation and melt rates can be calculated using meteorological data: air t...

The present study reports on the geochemical composition of soils and bacterial and fungal isolates determined in the soils surrounding the Komsomolsk tailings, Kuznetski Alatau, Russia. The areas with high concentration of As, Sb, Cd, Pb, and Zn were revealed. The assessment of metal and metalloid contaminants was conducted on the soils using Pollution index (PI), Enrichment Factor (EF), and Geo-accumulation Index (Igeo). The indexes indicated serious Pb, Cu, Zn, Cd, Co, As pollution especially for soils sampled ...
