摘要: 本文对冷泉细菌——Paenibacillus algorifonticola的代谢产物的提取分离进行了研究。P.algorifonticola可产生抑制白色念珠菌的水溶性物质。大孔树脂D101和XAD7HP串联使用脱除P.algorifonticola发酵液中的色素,树脂与发酵液比例为1:10(g/mL)为佳。脱色后发酵液中的活性物质可被强酸性阳离子交换树脂FPC22H吸附,0.5 mol/L的氨水可将活性物质洗脱下来,每10 g FPC22H可以吸附120 mL发酵液中的活性物质。本文研究结果为进一步分离纯化P.algorifonticola产抗白色念珠菌物质奠定了基础。

Abstract: This study focused on the extraction and purification of active constituents from a bacterium,namely Paenibacillus algorifonticola. P.algorifonticola can produce water-soluble constituents which showed inhibitory activity against Candida albicans. Macroporous resin D101 coupled with XAD7HP was used to absorb pigments from the fermentation broth of P.algorifonticola. The suitable ratio of resin (either D101 or XAD7HP) to fermentation broth was 10 g of resin to 100 mL of fermentation broth. No active constituents were adsorbed by the two resins.The active constituents were strongly absorbed by acidic cation exchange resin FPC22H and eluted by 0.5 mol/L ammonia.10 g FPC22H resin adsorbed 120 mL fermentation broth.The results of this study can be used for further purification of antibacterial-active constituents of P.algorifonticola.

Key words: Paenibacillus algorifonticola, ion exchange, macroporous resin, decolorize
