tailieunhanh - Isolation and selection of chitinase producing bacteria with antifungal activity against fusarium oxysporum from lilium rhizosphere soil

These chitinase-producing bacterial strains were tested for antagonistic activity against the causal agent of bulb and stem rots of lilies, Fusarium oxysporum, and the results indicated antifungal activity of the four strains HP02, VRQ9, HM03, and GL10. The HP02 strain had the highest level of chitinase activity and was capable of being antagonistic to Fusarium oxysporum. Based on morphological and biochemical characteristics, 16S rRNA gene sequencing, and phylogenetic analysis of this sequence along with sequences from GenBank, HP02 was identified as Bacillus subtilis. |
