文摘
- •
Magnetic stimuli-responsive biocatalytic membrane reactor was optimized.
- •
It was stable over a broad range of various operating parameters.
- •
Flux and feed concentration, related by reactor productivity were crucial parameters.
- •
Productivity increased with increased enzyme amount, despite the universal trend.
- •
There was no enzyme leakage, activity decay or TMP rise continuously over 240 h.
