Levan production by strains of Erwinia herbicola is common, and this property has some taxonomic significance for species differentiation within the "herbicola" group. The extracellular polysaccharide elaborated by strain 403 was characterized by nuclear magnetic resonance spectroscopy and methylation analysis. Results showed it to be a typical bacterial levan.
草生欧文氏菌菌株产生果聚糖很常见,这一特性对于“草生”菌群内的物种区分具有一定的分类学意义。通过核磁共振光谱和甲基化分析对菌株403产生的胞外多糖进行了表征。结果表明它是一种典型的细菌果聚糖。
