Antagonistic and enzymic activity of potential bearing Bacillus thuringiensis 4ant strain

Abstract

Dendroflora is an important component of all urban ecosystems, acts as an accelerator of biogeochemical processes in the soil and serves as a filter to clean the air of toxic compounds. However, the progressive growth of the impact on the urban ecosystem invariably leads to a different kind of dendro-pathogenic problems caused by abiotic and biotic factors. Therefore, the aim of our study was the development of a biological product based on microorganisms-antagonists of phytopathogens and based on the results of microbiological and ecological studies to highlight indigenous strains of Bacillus, having antagonistic activity against a variety of phytopathogenic microorganisms, i.e. trunk rots pathogens of elm.
