摘要: 研究复合型微生物絮凝剂产生菌的生长曲线变化在不同时期的pH值、 基质-葡萄糖、 硫酸铵含量、 絮凝活性、 产量变化、 细胞絮凝效果变化等. 结果表明, 在整个生长周期中,pH值基本不变;碳氮源变化显著, 并存在相关性; 进入稳定期后,60 h时,絮凝活性达到最大值97.35%, 此后, 絮凝活性数值下降, 但不明显, 絮凝剂产量最大值为3.02 g/L;细胞絮凝效果与细胞生长呈正相关性. 鉴定结果表明, 3种单菌分别为Brevibacterium mcbrellneri, Burkholderia glumae, Cryptococcus albidus var aerius.

Abstract: The changes in the content of both substrate glucose and ammonium sulfate, pH and flocculation activity and output of compound microbial flocculant in differ ent periods of growth cycle compound bioflocculant producingbacterium were studied. In the whole growth cycle, pH was stable, the change of carbon and nitro gen source was obvious, the content of nitrogen was consistent with the source of carbon; the maximum of flocculationactivity reached to 97.35% at 60 h point after steady period, then the numerical value of flocculation activity fell down, but not obvious. Flocculation activity had a wide region of largest value and the maximum output of flocculation (3.02 g/L) was in this region. The result of cell flocculation and growth of cell got positive pertinence. Appraisal result is: 3 bacteria are respectively Brevibacterium mcbrellneri, Burkholderia glumae and Cryptococcus albidus var aerius. The experimental result offered a foundationto further investigations of contributing factor on flocculation and mechanism. It provided gist in theory for culture in industrial application, too.

Key words: compound microbial, flocculation productbacterium, growth cycle, change of parameter
