  第十六篇 Appl Microbiol Biotechnol 2010
  
  Extraction of extracellular polymeric substances (EPS) from anaerobic granular sludges: comparison of chemical and physical extraction protocols
  
  在纯微生物培养中eps的主要成分是多糖，但也主要有蛋白质的，同时有腐殖酸，康醛酸还有核酸 .
  
  The dry weight (DW) content of the granular sludge was determined by drying a sample at 105 for 24 h. Then, the volatile dry weight (VDW) content of the granular sludge corresponds to the loss of mass after 2 h at 550。
  
  分析矿物成分：
  Analysis of the mineral composition of sludges was carried out first by a rinsing step with two volumes of deionized water added to one volume of sludge. Then,
  samples were centrifuged (500 rpm) for 5 min, and the supernatant was removed.These operations were carried out twice.To pre-oxidize sludge organic matter, 2 mL of hydrogen peroxide (30% Prolabo) was added to about 0.3 g of sludge for 48 h. To digest organic matter, 1 mL of nitric acid (69% Prolabo) and 3 mL of hydrochloric acid (37% Prolabo) were added to the samples for 24 h. Finally, the pretreated sludge was digested in a multiwave 3000 (Anton Paar) according to an adequate 45-min-long microwave program (a 5-min-long ramp to reach a power of 1,400 W, then a step of 20 min at 1,400 W, and 20 min to cool the sample). Samples were added up to 50 mL with deionized water.

  If one only concentrates on the residual material for the normal hydraulic and sludge retention times used, then clearly the degradation intermediates are eliminated from the group because they are not refractory.

  Separating those compounds that have entered the system through the in痷ent and those that have been produced by the system itself is not easy and one must ask how useful this information is to the operating facility.

  超滤是采用中空纤维过滤新技术，配合三级预处理过滤清除自来水中杂质；超滤微孔小于0.01微米，能彻底滤除水中的细菌、铁锈、胶体等有害物质，保留水中原有的微量元素和矿物质

  GPC using Sephadex gel could not generally be used for the fractionation of organic pollutants in water solely by MW, but that it was a useful technique for separating various organic pollutants based on chemical structure.

  From the practical viewpoint it is very important to determine which are readily degradable and which are refractory and they assumed that the polymers which are commonly present in most microbial cells (e.g. nucleic acids, peptidoglycans and phospholipids) are easily degradable by many micro-organisms but that, on the contrary, speci®c and unrepeatedly synthesised polymers (e.g. extracellular heteropolysaccharides or polysaccharidic components of lipopolysaccharides) are refractory.

  在排阻色谱中，一些化合物因为离子排阻或者复杂结构，会比标准曲线中的物质跑得快，从而会对分子量造成过高的估计。而另外一些化合物可能由于吸附或者静电作用与填充柱吸附，分子量会被低估。
  
  色谱分析需要蒸发或者冷冻干燥来增加浓度，这样会改变可溶性化合物的大小。

  smp分子量分布情况
  1 在很多生物处理的废水出水中，高分子量的化合物的含量比入水中的高。
  2 生物废水处理后化合物的分子量在(<0.5 to >50 kDa)
  3 分子量严重受操作条件的影响。SRT越大，分子量越高。
  4 分子量的分散受底物类型的影响。
