| 中文摘要 |
| 探讨了在纯培养和混合培养的条件下,2株芽孢杆菌F2和F6生产高效絮凝剂过程中对碳源的利用情况.研究表明,多种分子量在200以下的有机物能够作为碳源用于高效絮凝剂的生产,包括:单糖、双糖、醇、有机酸和酯类等,具有一定的普适性.发现利用废糖蜜、生物制氢废液和纤维素糖化液等廉价的生物质废料能够生产出性能良好的生物絮凝剂.

| 英文摘要 |
| Two strains of Bacillus sp. F2 and F6 could produce bioflocculants with high flocculating effects by pure culture and mixed culture. Many kinds of carbon sources could be utilized. Organic compound which molecular weight under 200 such as saccharide, alcoholic aldehyde, ester and organic acid were favorable for producing bioflocculant. And some low-cost biomass scrap could be used as good carbon sources for industrialized production of bioflocculants, such as waste beet molasses, cellulose's fermentation residue and sewage of hydrogen producing reactor.
