Core microbe Bifidobacterium in the hindgut of calves improves the growth phenotype of young hosts by regulating microbial functions and host metabolism by Yimin Zhuang, Duo Gao, Wen Jiang, Yiming Xu, Guanglei Liu, Guobin Hou, Tianyu Chen, Shangru Li, Siyuan Zhang, Shuai Liu, Jingjun Wang, Jianxin Xiao, Mengmeng Li, Wei Wang, Shengli Li, Zhijun Cao

“…Furthermore, pathways involved in carbohydrate degradation, glycolysis, and biosynthesis of propionate and proteins were active, while methane production was inhibited. In addition, the diversity and richness of hindgut resistome in cluster2 were lower than those in cluster1. …”

Modulating the sulfurization procedure to decrease by-product formation for one-step catalytic synthesis of sulfur-containing chemicals by ZhiZhi Xu, Jian Fang, Min Luo, Dedong He, Dingkai Chen, Jichang Lu, Yongming Luo

“…Otherwise, the strong bonding of Mo-S(O) bond with CO molecule over K-decorated 2H-MoS2 phase can lead to the breakage of CO bond, promoting the formation of CHx species and the occurrence of methanation side reaction. This strategy could provide the useful guidance for the fine regulation of the main and side reaction pathway for producing important chemicals from carbon and sulfur basic materials.…”

Development of a GIS-based register of biogas plant sites in Lower Saxony, Germany: a foundation for identifying P2G potential by Mareike Plinke, Jonas Berndmeyer, Jochen Hack

“…Spatially resolved plant information on production capacity suggests that three quarters are suitable for inclusion in a methanization concept. Because plants at 85% of the sites will no longer be subsidised by 2035, end-of-subsidy strategies will soon become relevant. …”

A szélsőséges időjárási jelenségek hatásai (Effects of the Extreme Weather Events) by Tamás Molnár, Katalin M. Barna
