摘要：

Two types of anaerobic sludge were analyzed for ECP (extracellular polymers) content under five extraction conditions. Results showed that EDTA was more effective than formaldehyde as an extractant. Increase of temperature and addition caustic also enhanced the extraction. The ratio between carbohydrate and protein fractions of ECP for both acetate- and benzoate-degrading sludge was 0.16-0.18. The former sludge had only 40-45% of ECP as in the latter sludge.
