| Abstract [eng] |
In recent years, a decrease in soil fertility has been recorded all over the world. The main factors reducing soil fertility are global climate change, temperature rise, changing soil moisture and water shortage, and the rapid decrease in organic and mineral substances available for plant development. With the rapid development of biotechnology, bioproducts are increasingly being used to restore degraded soil, which improve the efficiency of plant nutrition, cause changes in vital and structural processes, and increase product yield and quality. During this project, an innovative bioproduct prototype was created to improve plant vegetative processes. It combines microorganisms isolated and selected from the rhizosphere of the roots of various agricultural plants, which secrete biologically active compounds that stimulate plant vegetative processes. During the scientific project, the composition of the most compatible selected microorganisms was determined, which is able to provide plants with an effective supply of nutrients and resistance to abiotic and biotic stresses. Laboratory-scale fermentation processes have also been developed, in which several different bacterial genera are cultivated in one environment, and such results can be applied in large-scale industrial fermentation processes in the future. The biopreparations Priestia sp. IIIDEG4, Paenibacillus sp. IIIDEG36 + Priestia sp. IIIDEG93 and Bacillus sp. IJAK27 + Pseudomonas sp. IJAK44 + Streptomyces sp. IJAK91, composed during the fermentation processes, have been identified as competitive microbiological products with unique properties and effective applicability in agriculture. |
