Within the framework of this study, the micromycete Fusarium sporotrichioides was isolated from wheat grain, a collection of isolates of endophytic microorganisms with antagonistic activity against this pathogen was formed, and their antagonistic activity was studied. By the mechanism of action, the isolates are classified as strains exhibiting fungistatic antibiotic antagonism, that is, inhibition of fungal growth occurred at a distance under the influence of antibiotic substances produced by the antagonist, with the formation of a “sterile” zone between cultures; and strains with fungistatic alimentary type of antagonism, expressed in stopping the growth of the pathogen upon contact with the antagonist colony. Stepwise screening of microorganisms-antagonists in in vitro and in vivo experiments made it possible to select technological and safe isolates with high antifungal activity and the possibility of using them as biofungicide producers. Three isolates from among the most active aboriginal endophytic microorganisms belonging to the species Bacillus subtilis are promising for introduction into the biocenosis with the aim of long-term regulation of the density of phytopathogenic populations of Fusarium sporotrichioides.
Due to the annual increase in emissions of animal and poultry waste into the environment, scientists around the world are increasingly interested in improving technologies to accelerate the processing of agricultural waste. In the presented work, 6 microorganisms were selected: Lactobacillus spp., thermophilic bacteria (Bac. subtilis), Clostridium spp., Penicililum spp., Saccharomyces cerevisiae, Micrococcus nishomyaensis) to accelerate the processing of animal waste. The toxicity and toxigenicity of newly isolated strains of microorganisms was assessed. At the same time, it was found that the strains of microorganisms do not have toxicity and toxigenicity.
scite is a Brooklyn-based organization that helps researchers better discover and understand research articles through Smart Citations–citations that display the context of the citation and describe whether the article provides supporting or contrasting evidence. scite is used by students and researchers from around the world and is funded in part by the National Science Foundation and the National Institute on Drug Abuse of the National Institutes of Health.
