The 83 strains of microorganisms including molds, bacteria, yeast and actinomycetes, which were isolated from soil and active sludge were found to produce the substances which can flocculate kaolin clay. Among them, four strains with high flocculating activity was identified as Sporolactobacillus sp. (GC3), Arthrobacter sp. (SB6),Pseudomonas sp. (SB8) , Aeromonas sp. (GC24). Growth study in shaking flasks was conducted for obtaining high flocculant production. The highest level of flocculating substance accumulation...

The 83 strains of microorganisms including molds, bacteria, yeast and actinomycetes, which were isolated from soil and active sludge were found to produce the substances which can flocculate kaolin clay. Among them, four strains with high flocculating activity was identified as Sporolactobacillus sp. (GC3), Arthrobacter sp. (SB6),Pseudomonas sp. (SB8) , Aeromonas sp. (GC24). Growth study in shaking flasks was conducted for obtaining high flocculant production. The highest level of flocculating substance accumulation (0. 5-0. 9g/L) were attained after 65h cultivation at 30℃ with initial medium pH 7.5-8. 5 and proper aeration. These bioflocculants were purified by ethanol precipitation, gel chromatography and dialysis. The isolated polymers possessed chemical characteristics of nucleoprotein (MF-3, MF-6, MF-8) and polyglucoprotein (MF-24). Their molecular weights were larger than 106 dalton and they have widely flocculating activity against both organic and inorganic materials. It was detected by experiments that neither of the four strains has plasmids. The pathogenicity of their cells and toxicity of the bioflocculants had also been studied.

筛选到83株絮凝剂产生菌,其中絮凝活性最高的四株分属于芽孢乳杆菌属(Sporolactobacillus GC3)、节细菌属(Arthrobacter SB6)、假单胞菌属(Pseadomonas SB8)、气单胞菌属(Aeromonas GC24)。四株菌在生长过程中均可产生胞外絮凝物质,在最适培养条件下絮凝剂产量为0.5—0.9g/L。纯化后的四种絮凝剂中,三种为核蛋白,一种为糖蛋白,均为高分子量物质(MW>10~6)。四株菌均不含质粒。12—30g/L的絮凝剂在1小时内对所有供试材料均有较好的絮凝效果。动物急性毒性实验表明,20—70倍于使用浓度的絮凝剂对昆明鼠无毒。

Taking GCI medium to culture and isolate three strains of high coagulation microbes which could produce bio-coagulants, from activated sludge of Qu-yang Sewage Treatment Plant and setting of Yu-jing Creek. Several kinds of polluted water such as kaolin suspension could be purified effectively by using these bio-coagulants. Coagulation could be apparently improved when using CaO as the coagulating-aid. It showed that excellent bio-coagulants could be produced when a 72 hours continued cultivation was performed....

Taking GCI medium to culture and isolate three strains of high coagulation microbes which could produce bio-coagulants, from activated sludge of Qu-yang Sewage Treatment Plant and setting of Yu-jing Creek. Several kinds of polluted water such as kaolin suspension could be purified effectively by using these bio-coagulants. Coagulation could be apparently improved when using CaO as the coagulating-aid. It showed that excellent bio-coagulants could be produced when a 72 hours continued cultivation was performed. On the process of bio-coagulants isolation, a proper centrifugal conditions should be adpoted, because too fast centrifugation may result obvious decrease in coagulating efficiencies.
