求翻译：由于胞外多聚物的主要来源是微生物生长过程中的分泌到细胞外的物质[76]，磁粉对微生物生长的促进作用，使得其胞外多聚物产生量大大增加。是什么意思？

As the extracellular polymer is the main source of microbial growth process of the material secreted into the extracellular [76], magnetic role in promoting the growth of microorganisms, making the extracellular polymer produced is greatly increased.

Because many polymer outside cells is the main source of growth of microorganisms in the secretion of extracellular material [ 76] and magnetic powder to promote the growth of microorganisms, which makes their role more gathered outside cells produced significantly higher.

Because outside the butcher gathers the main origin is in microorganism growth process secretion extracellular material [76], the magnetic powder the promoter action which grows to the microorganism, causes outside its butcher to gather the thing to have the quantity big increase.

Because of the major sources of extracellular polymeric substances are secreted to the extracellular microbial growth substances [76], promoting effect of magnetic powder on the growth of microorganisms, making its extracellular polymeric substances have greatly increased.

Because extracellular polymeric substances major sources of microbial growth is secreted into extracellular substances in [the 76], magnetic powder on microbial growth promoting effect, greatly increases its extracellular polymeric substances.
