Highly Efficient Capture of Marine Microbial Strains in Seawater Using Bare Fe3O4 Magnetic Beads.

We develop a method to capture marine bacterial strains at high efficiency to replace the conventional two-step collecting method. Lab-made, Fe3O4 magnetic beads were used to firstly verify the feasibility of capture in artificial seawater, using Bacillus velezensis. Almost 100% of the bacteria could be captured and separated within 10min. Then, the salinity of capture medium was proved to have the most marked effect on the capture process. After that, the broad application and high efficiency of capture were verified using four different bacterial strains from the Pacific Ocean. Subsequently, through adjusting the salinity, the capture efficiency for Pseudoalteromonas sp. and Halomonas meridiana was increased from 20 to ~ 80% in a seawater system, which was used to simulate the in-situ capture conditions. Finally, mixed strains in seawater were successfully captured, and their genomic DNAs were isolated and analyzed. Bare Fe3O4 magnetic beads were initially applied to capture marine microorganisms and this method is convenient and highly efficient and thus has great potential to replace the conventional two-step method.

First successful capture and satellite tracking of a West Indian manatee (Trichechus manatus) in Panama: feasibility of capture and telemetry techniques

It is currently unknown how important the Central American countries south of Belize are as a link between manatee populations in the north (Belize and Mexico) and populations in South America. Therefore, apart from knowing where manatees are found, it is important to understand how manatees are using these habitats and if they are moving between countries or distinct population centers. Here we report the results of a multi-national and multiinstitutional collaboration resulting in the first successful capture and satellite tracking of a West Indian manatee in southern Central America

CARBON DIOXIDE RECOVERY AND DISPOSAL FROM LARGE ENERGY SYSTEMS

▪ Abstract Increases in greenhouse gas emissions and concerns about potential global climate change are stimulating worldwide interest in the feasibility of capture, disposal, and utilization of CO2 from large energy systems. Technology to capture CO2 from power plant flue gas, while energy intensive and expensive, is commercially available. Capture from advanced combustion systems offers a further opportunity to significantly reduce cost and energy requirements of CO2 capture compared to that from today's pulverized coal power plants. No viable disposal options exist today for large quantities of captured CO2. Ocean disposal of CO2 and geological storage, especially in depleted oil and gas wells, are leading candidates. Although some niche utilization may occur, utilization seems unlikely to become a major sequestration option. Since CO2 capture and sequestration is a relatively expensive mitigation option, it can be regarded as an insurance policy. However, since CO2 mitigation options are few in number, continued research to reduce the costs of CO2 capture and to develop feasible sequestration options is important.
