L. Zhang和R.G.博奇1996.叶枯病是甘蔗的一种严重的机械传播疾病，由木质部入侵细菌白纹黄单胞菌引起。该病原体产生一个家族的植物毒素和抗生素称为albicidins。从X. albilineans侵入甘蔗组织，并使用简单的测定进行筛选以区分抗性机制。一株对albicidin具有较强酶解能力的细菌被鉴定为分散泛菌（Pantoea dispersa，syn. Enwinia acetonola）。当与10倍过量的X共接种时，使albicidin解毒的分散泛菌菌株SB 1403提供了对叶枯病的几乎完全的生物防治。albilineans细胞转化为高度易感的甘蔗品种。
L. ZHANG AND R.G. BIRCH. 1996. Leaf scald is a serious, mechanically transmitted disease of sugar cane, caused by the xylem‐invading bacterium Xanthomonas albilineans. The pathogen produces a family of phytotoxins and antibiotics known as albicidins. Bacterial strains resistant to albicidin were isolated from X. albilineans‐invaded sugar cane tissues, and screened using a simple assay to distinguish resistance mechanisms. One bacterial strain with a strong capacity for enzymatic detoxification of albicidin was identified as Pantoea dispersa (syn. Enwinia herbicola). Pantoea dispersa strain SB1403 which detoxifies albicidin provided almost complete biocontrol against leaf scald disease when co‐inoculated with a 10‐fold excess of X. albilineans cells into a highly susceptible sugar cane variety.
