A characteristics of three extracellular metabolites produced by Bacillus coagulans strain that were supposed to be responsible for its fungistatic activity against Trichothecium roseum has been done by TLC, GC-MS and Western blotting methods. It was shown that these compounds of molecular weights as 41, 45 and 65 kDa secreted to the medium by bacteria had glycoprotein properties and did not become inactive when boiled for 20 min., as characteristic for glycoprotein.
