Screening of Biodegradation Strains in Wastewater from Yeast Fermentation Industry
摘要
Abstract
[Objective] The study aimed to screening of biodegradation strains in wastewater from the yeast fermentation industry and study the optimum degradation conditions for degrading the water by the strain. [ Method] Taking waste water from the fermentation industry in some enterprise in Yichang City as the only carbon source, through selective and enrichment, domestication, and streaking and purification, the strain SA was screened from the sludge in Yichang area and the combination methods of morphology observation and physiological and biochemical experiment was used to identify the characteristic of the strain. With the temperature, pH value and substrate concn. As the influence factors, the best degradation conditions for degrading the wastewater from the fermentation industry by the strain were confirmed through an orthogonal test. [Result] SA was identified as Pseudomonas stutzeri spp. The best conditions obtained from the orthogonal experiment for degrading the wastewater from the fermentation industry by the strain SA were as follows: the temperature was 35 ℃, the pH value was 6.0 and the substrate concn. Was 600 ml/L. Under this optimum degrading condition, the removal rate of COD by the wastewater from the fermentation industry reached 73.1% , showing that the strain had stronger mineralization ability. [Conclusion] The strain had stronger ability for degrading the wastewater from the fermentation industry under the aerobic.关键词
