在这里，我们报告的复合材料的生物活性微生物放置在合成聚合物基质。这些所谓的“活复合材料”被用于金螯合（微球菌luteus）和亚硝酸盐的生物修复（Nitrobacter winogradskyi），以证明功能。为了制备活性复合材料，首先将细菌包裹在水溶性聚合物纤维（聚（乙烯醇），PVA）中，然后通过化学气相沉积（CVD）用疏水性聚（对二甲苯）（PPX）的壳涂覆纤维。细菌与聚合物材料的组合确保了细菌在水性环境中的稳定性和生物活性数周。
Herein, we report on composite materials of biologically active microorganisms placed in a synthetic polymer matrix. These so-called "living composites" were utilized for gold sequestration (Micrococcus luteus) and bioremediation of nitrite (Nitrobacter winogradskyi) to demonstrate functionality. For the preparation of the living composites the bacteria were first encased in a water-soluble polymer fiber (poly(vinyl alcohol), PVA) followed by coating the fibers with a shell of hydrophobic poly(p-xylylene) (PPX) by chemical vapor deposition (CVD). The combination of bacteria with polymer materials assured the stability and biologically activity of the bacteria in an aqueous environment for several weeks.
