AI Article Synopsis
- Lithium manganese oxide adsorbents have been created to extract lithium from seawater efficiently, but microfouling by marine bacteria poses a challenge.
- Research conducted involved using both coated and non-coated frames of these adsorbents to identify bacterial species responsible for fouling, focusing on samples collected over 30 days.
- The study found that Pseudoalteromonas and Vibrio were the main bacteria on the non-coated adsorbents, while the antifouling agent significantly reduced Vibrio presence, highlighting the effectiveness of antifouling strategies for improving lithium recovery.
Article Abstract
Lithium manganese oxide-based adsorbents have been developed for the recovery of lithium from seawater. To maximize the recovery efficiency, it is important to prevent microfouling of lithium adsorbents by marine bacteria. To identify the marine bacteria that cause biofouling against the lithium adsorbents, lithium adsorbents were installed into a non-coated frame or a frame coated with an antifouling agent soaked in seawater. Microorganisms from the surface of lithium adsorbents were collected for 30 days at 10-day intervals, cultured in marine broth, isolated, and identified by 16S rDNA sequencing. Pseudoalteromonas and Vibrio were constituted to 35.6 and 28.8 % of total isolates, respectively, and were predominant in the non-coated frame, whereas Vibrio was poorly isolated (2.3 %) from the antifouling agent-coated frame. In this study, antifouling strategy for maximum lithium recovery efficiency in the marine area takes account of Pseudoalteromonas and Vibrio.
