Antifungal potential of biosurfactants produced by strains of

Phytopathogenic fungi cause significant damage to agriculture, reducing or destroying the crop. There are several ways to control fungal diseases, such as the use of disease-resistant plant varieties, organic farming, and the use of fungicides. One of the methods of combating phytopathogens is the use of biological products, one of which is biosurfactants. Biosurfactants are surfactants produced in the course of life. They are able to reduce fungal growth and increase plant disease resistance, improve plant growth and yield, and act as adjuvants to improve wetting and solubility of fertilizers. In the course of this work, the fungicidal activity of biosurfactants formed by Bacillus mojavensis PS17 was assessed against pathogens of the genera Fusarium and Verticillium. It has been established that the biosurfactant is able to reduce the coverage area of Fusarium and Verticillium fungi in in vitro experiments by 39 and 43%. Thus, it can be concluded that the biosurfactant produced by Bacillus mojavensis PS17 has antifungal activity

Characterization of biosurfactants produced by the

Biosurfactants are amphiphilic substances with a wide range of uses. Biosurfactants are being researched in various areas of biotechnology. They are especially widely used in the development of new environmentally friendly methods for increasing oil production, as well as in agriculture as an effective biocontrol agent. However, the possibility of finding strains producing biosurfactants and the efficiency of their production is a separate task for research. The aim of this work was to evaluate the dynamics of biosurfactant production by the Bacillus amyloliquefaciens VKMA B-12464 strain, as well as to evaluate its chemical nature. During the research, the resulting biosurfactant was characterized by TLC and IR spectroscopy. It has been established that the biosurfactant produced by Bacillus amyloliquefaciens belongs to lipopeptides, and its highest yield is observed on the 7th day of cultivation
