In a field experiment, Pseudomonas cepacia J82rif and J51rif increased sunflower emergence in the presence of the fungus Sclerotinia sclerotiorum. Pyrrolnitrin, aminopyrrolnitrin, and monochloroaminopyrrolnitrin were isolated from J82 and identified by using thin-layer chromatography, high-performance liquid chromatography, and electron impact-mass, UV, and infrared spectroscopy. In growth chamber experiments, two antibiosis-negative mutants were not different from the parent strain in protecting the seeds from the fungus.
在田间试验中,洋葱伯克霍尔德菌J82rif和J51rif在核盘菌存在的情况下提高了向日葵的出苗率。从J82中分离出了硝吡咯菌素、氨基硝吡咯菌素和一氯氨基硝吡咯菌素,并通过薄层色谱法、高效液相色谱法以及电子轰击质谱、紫外和红外光谱法进行了鉴定。在生长室试验中,两个抗生阴性突变体在保护种子免受真菌侵害方面与亲本菌株没有差异。
