Methanothermobacter Marburgensis

AbstractIn this study (Taubner et al.2018), three different methanogenic archaea (Methanothermococcus okinawensis, Methanothermobacter marburgensis, and Methanococcus villosus) were tested for metabolic activities and growth under putative Enceladus-like conditions, including high pressure experiments and tests on the tolerance towards potential gaseous and liquid inhibitors detected in Enceladus’ plume. In particular, M. okinawensis, an isolate from a deep marine trench (Takai et al.2002), showed tolerance towards all of the added inhibitors and maintained methanogenesis even in the range of 10 to 50 bar. Further, we were able to show that H2 production based on serpentinization may be sufficient to fuel such methanogenic life on Enceladus. The experiments revealed that methanogenesis could, in principle, be feasible under Enceladus-like conditions.

And Control

As the last working procedure in the paper production process, re-winder control technology is crucial to the quality of finished paper scroll. To obtain the paper scroll with inner tight and outer loose, the control of bottom rollers must satisfy the double closed-loop feedback control with torque difference. While the feedback control exists time-delay and may cause the slowness of system response. Here on the basis of re-winder production process and control requirements, a novel feed-forward control tactics is proposed to combine with feedback control. According to the compensation of feed-forward control, rapid system response is obtained and system performance is improved. And corresponding simulation shows the validity and feasibility of the feed-forward control tactics.
