Extracellular polymeric material of granular sludges contained 1.7-2.7% carbohydrates, 2.5-5.196 nucleic acids and 8.3-l&3% proteins of total suspended solids (TSS). The ash content of the granular sludges varied from ll-21% and was an equal combination of metalsmainly calcium, sodium, magnesium, potassium, phosphorus and iron-and non metals in the form of clay. The results indicated that feed mineral concentration had an overall effect on the mineral composition of granular sludges and that specific uptake of preferred minerals such as magnesium, iron and phosphorus occurred depending upon the operational and environmental conditions. Significant variation was found in the dominant methanogenic groups.
