一种降解PVA废水菌群的制备方法
摘要：
本发明提供一种降解PVA废水菌群的制备方法，将活性污泥以4%的体积接种量接入装有100ml降解培养液的250mL锥形瓶中，摇瓶转速150 r/min，28℃培养，培养1个半月后，逐步提高PVA浓度，经过5个周期的再驯化，获得能够有效降解PVA的混合菌种。由于能够降解PVA的微生物在自然界中分布不广泛，单一微生物难于彻底降解PVA，而且浓度较低，所以本研究的混合菌群是一个不错的选择，降解浓度高，5g/L的PVA废水降解效率接近80%。
摘要（英）：

The invention provides a preparation method of PVA waste water degradation flora. Active sludge is inoculated into a 250mL conical beaker containing 100ml of degradation culture solution at the volume of 4 percent; the rotation speed of a shake flask is 150 r/min; the culture is performed at the temperature of 28 DEG C; after the culture for 1.5 month, the PVA concentration is gradually increased; after the 5 periods of secondary domestication, the mixed strains capable of realizing effective PVA degradation can be obtained. The distribution of the microorganisms capable of degrading the PVA is not wide in the nature; the single microorganism is difficult to thoroughly degrade the PVA, and the concentration is low, so that the mixed flora studied by the invention is a good choice; the degradation concentration is high; the 5g/L PVA waste water degradation rate is close to 80 percent.
