  • 摘要: 考察了微生物絮凝剂产生菌Bacillussp.B-2发酵生产絮凝剂的絮凝特性。研究表明,该菌在生长过程中产生絮凝剂并将其分泌到细胞外,每升发酵液可制得絮凝剂粗品1.7g,絮凝活性最高达97%以上,絮凝效能优于目前市售化学絮凝剂。该絮凝剂凝聚絮凝高岭土悬浊液最适宜的pH值在大于7的偏碱性条件Ca2+,Mg2+,Mn2+,Al3+等二价、三价金属离子对其絮凝具有促进作用,且随着Ca2+浓度的增加,促进作用加强。
    Abstract: Flocculation characteristics of bioflocculant produced by Bacillus sp. B-2 were studied. It showed that Bacillus sp. B-2 produced extracellular flocculant with the highest flocculation activity of 97% superior to common used organic or inorgantic flocculant during its growth. Under the opti-mum conditions, the amount of flocculant production was 1.7 g· l-1. The suitable pH value for the flocculant to flocculate Kaolin clay suspension was higher than 7. Cu2+, Mg2+, Mn2+, Al3+ facilitate flocculation activity of microbial flocculant and the flocculating activity was intensifed with increase in Ca2+ concentration.

摘要: 考察了微生物絮凝剂产生菌Bacillussp.B-2发酵生产絮凝剂的絮凝特性。研究表明,该菌在生长过程中产生絮凝剂并将其分泌到细胞外,每升发酵液可制得絮凝剂粗品1.7g,絮凝活性最高达97%以上,絮凝效能优于目前市售化学絮凝剂。该絮凝剂凝聚絮凝高岭土悬浊液最适宜的pH值在大于7的偏碱性条件Ca2+,Mg2+,Mn2+,Al3+等二价、三价金属离子对其絮凝具有促进作用,且随着Ca2+浓度的增加,促进作用加强。
