研究了微生物对橡胶材料的生物攻击，以评估生物技术对废旧橡胶制品的精炼和回收的可能贡献。适应微生物富集培养物与轮胎屑材料几个月导致微生物的生长增强，特别是在NR和SBR上。为了阐明细菌对橡胶等疏水物质作用的一般机制，选择不同种类的聚异戊二烯进行进一步研究。聚类异戊二烯被用作富集微生物的唯一营养源，所述微生物显示出材料的相当大的劣化和橡胶烃的增强的矿化。
The biological attack of microorganisms on rubber materials was investigated in order to evaluate possible contributions of biotechnology for refinement and recycling of used rubber products. Adaptation of microbial enrichment cultures with tire crumb material for several months resulted in enhanced growth of microorganisms especially on NR and on SBR. In order to elucidate general mechanisms of bacterial action on hydrophobic substances like rubbers, different kinds of polyisoprenes were chosen for further examination. The polyisoprenoids were employed as sole nutrient source for enrichment of microorganisms that show considerable deterioration of the materials and enhanced mineralization of the rubber hydrocarbon.
