Application of yeasts in wastewater treatment
- 海洋环境－已发表论文 
酵母菌既具有细菌单细胞、生长快、能形成很好的絮体、适应于各种不同的反应器等特点,又具有真菌细胞大、代谢旺盛,耐酸、耐高渗透压、耐高浓度的有机底物等特性,因而可用于多类难处理有机废水的处理,并且具有处理效率高、污泥负荷高、占地面积小、剩余污泥可回收用作饲料蛋白等特殊的优越性。酵母菌废水处理技术有望成为常规好氧和厌氧处理技术的重要补充而在工业废水治理中发挥重要作用。Yeast cells have both the virtues of bacteria (living in single cell, growing fast, forming good flocs and suitable for various bioreactors) and fungi (high tolerance to acids, high salt and high concentration of substrates). When used in wastewater treatment, the yeast technology permits a high COD load and a small bioreactor and could endure various bad wastewater environments such as acid, high osmotic pressures and so on. Its residual sludge normally contains high protein and can be used as good additives in animal food. So this technology is expected to be a promising supplement for traditional aerobic and anaerobic wastewater treatment techniques to solve some intractable problems in industrial pollution.
