白菜軟腐細菌(Erwinia aroideae)在不同土壤条件下的存活时期

白菜軟腐細菌(Erwinia aroideae)在不灭菌的土壤中可以存活11天至14天。土壤中的微生物总数(指可以在牛肉汁(月柬)培养基上发育的微生物)因軟腐細菌的加入而起剧烈的波动。当軟腐細菌进入土壤中后24小时,軟腐細菌的数量銳减而土壤中的其他微生物数量上昇,以后亦逐漸递  (本文共9页) 阅读全文>>

Potential Distribution of Alien Invasive Species and Risk Assessment:a Case Study of Erwinia amylovora in China

Alien invasive species represent a severe risk to biodiversity and economy, as in the case of fire blight (Erwinia amylovora), a bacterial disease that originated in North America, which may be released into new locations by means of fruit trade. On the basis of the knowledge of Erwinia amylovora's biophysical characteristics and environmental data, the geographic information system (GIS) has been applied to determin...  (本文共8页) 阅读全文>>

Molecular Weight and Aggregation of Erwinia Gum in Aqueous Solutions

Erwinia(E) gum is composed of glucose, fucose, galactose and glucuronic acid. The weightaverage molecular weights M w, numberaverage molecular weights M n and intrinsic viscosities[η] of the four fractions and the unfractionated E gum in aqueous solutions at desired temperatures were studied by light scattering, membrane osmometry, size...  (本文共7页) 阅读全文>>

Simplification of vacuole structure during plant cell death triggered by culture filtrates of Erwinia carotovora

Vacuoles are suggested to play crucial roles in plant defense-related cell death. During programmed cell death,previous live cell imaging studies have observed vacuoles to become simpler in structure and have implicated this simplification as a prelude to the vacuole's rupture and consequent lysis of the plasma membrane. Here, we examined dynamics of the vacuole in cell cycle...  (本文共9页) 阅读全文>>
