| 摘 要： | 从滇重楼(Paris polyphylla var.yunnanensis)地下茎中分离和鉴定出两种细菌——蜡状芽孢杆菌(Bacillus cereus)和产碱假单胞菌(Pseudomonas alcaligenes),以及三种真菌——黑团孢霉(Periconia sp.)、白色厚顶孢霉(Pachnocybe albida)和重楼索霉(Hormomyces paridiphilus)。对蜡状芽孢杆菌、产碱假单胞菌和重楼索霉进行了液体培养并测定了胞外多糖含量，结果表明重楼索霉可分泌大量胞外多糖，这可能是导致滇重楼地下茎胶质化和多糖含量增加的原因。

| Abstract: | Two bacteria and three fungi were isolated from the hypogeal stems of Paris
polyphylla var. yunnanensis. The bacteria were identified as Bacillus cereus and
Pseudomonas alcaligenes, and the fungi were identified as Periconia sp., Pachnocybe
albida and Hormomyces paridiphilus. The results on liquid culture of B.cereus,
P.alcaligenes and H.paridiphilus indicated that the colloidization and polysaccharide
content increasing in hypogeal stems of P.polyphylla var. yunnanensis were due to the
extracellular polysaccharide secretion of the parasitical fungus H.paridiphilus. |
