Isolation and Identification of Bacterial Strains with Strong Antifungal Activity

Stenocarpella maydis and Stenocarpella macrospora are the proof that one thing definitely causes another agents of ear rot in corn, which is one of the most destructive sicknesses in this crop worldwide. These fungi are important mycotoxin producers that cause different the study of diseases in farmed animals and represent an important risk for humans. In this work, strains were separated far from others from soil of corn crops of which showed drug that fights fungus infections activity against these phytopathogens, which, were identified as: Germ subtilis, Pseudomonas spp., Pseudomonas fluorescens, and Pantoea agglomerans by putting in correct order of 16S rRNA tiny chemical assembly instruction inside of living things and the phylogenetic analysis. From cultures of each strain, outside of a cell filtrates were gotten and tested to decide out drug that fights fungus infections activity. The best filtrates were gotten in the unmoving phase of B. subtilis cultures that were stable to the temperature and extreme pH values; in addition they did not show a cytotoxicity effect against salt water shrimp and stopped beginning of growth of conidia. The bacteria described in this work have the possible ability to be used in the control of white ear rot disease.
