The spatiotemporal variations in microalgae communities in vertical waters of a subtropical reservoir.

The construction of cascade reservoirs increases eutrophication and exacerbates algal blooms and thus threatens water quality. Previous studies on the microalgae in reservoir have mainly focused on the spatio-temporal patterns of surface microalgae communities at the horizontal scale, while few studies have simultaneously considered the successions of microalgae in vertical profiles including the sediments and the effects of the nutrients release and microalgae in sediments on microalgae in upper waters. In this study, we investigated the effects of microalgae and physico-chemical parameters in waters and sediments on the successions of vertical microalgae communities in Xipi Reservoir, Southeast China.

[Diversity and community characteristics of organic phosphate-mineralizing bacteria in the sea area between Minjiang Estuary to Pingtan.].

Microbial mineralization of organic phosphorus is an important component of marine phosphorus cycle. The research on organic phosphate-mineralizing bacteria (OPB) is helpful to reveal microbial driving mechanism of organic phosphorus mineralization in eutrophic sea area. The diversity and community characteristics of OPB were examined by Illumina high-throughput sequencing using the primer sets in the sea area between Minjiang Estuary to Pingtan in April (spring) and July (summer) 2019.

MgH/CuO Hydrogen Storage Composite with Defect-Rich Surfaces for Carbon Dioxide Hydrogenation.

Thermal conversion of CO to value-added chemicals is challenging due to the extreme inertness of the CO molecule and the low selectivity of products. We reported a defect-rich MgH/CuO hydrogen storage composite from mechanochemical ball-milling for the catalytic hydrogenation of CO to lower olefins. The defect-rich MgH/CuO hydrogen storage composite achieves a C-C selectivity of 54.
