在几个月的时间内研究了生长在层状波纹碳（LCC）电极上的初级和次级电活性生物膜的性能。在6.7 mA cm（-2）的平均投射电流密度下，所研究的次级电活性生物膜在整个实验期间优于初级生物膜（3.0 mA cm（-2））。同时，初级和次级生物膜都表现出约89%的恒定库仑效率。该研究进一步表明，三维电极（如LCC）允许持续的长期性能，而不会显著降低电极性能。
The performance of primary and secondary electroactive biofilms grown on layered corrugated carbon (LCC) electrodes was studied over a period of several months. With an average projected current density of 6.7 mA cm(-2), the studied secondary electroactive biofilms outperformed the primary biofilms (3.0 mA cm(-2)) over the entire experimental period. At the same time, both, primary and secondary biofilms, exhibited a constant Coulomb efficiency of about 89%. The study further illustrates that three-dimensional electrodes such as LCC allow a sustained long-term performance without significant decrease in electrode performance.
