Study on Screening and Degradation Effect of Autotoxin-Degrading Bacteria in Muskmelon

The autotoxins of muskmelon are one the most important reasons for continuous cropping obstacle muskmelon, which main components phenolic acids. Phenolic acids can inhibit growth and development plants. purpose this study was to screen strains that degrade in soil. Using as sole carbon source, were isolated screened by dilution plate method, could efficiently various abilities measured HPLC, effects degrading soil verified a pot experiment. After identification, strain T58 identified Burkholderia sp., T79 H16 Pseudomonas T15 sp. results showed that, after 21 days culture, degradation rates ferulic acid, p-coumaric vanillin sinapic acid H16, T79, 100%, respectively. Additionally, gallic four also 100%. In study, it found autotoxin-degrading bacteria had good on acids, not only alleviate toxic but promote seedlings.
