Method for conversion of oil-containing algae to 1,3-propanediol The present invention relates to a process for oxidizing renewable polyunsaturated fatty acids eicosapentaenoic acid (EPA) and docosahexaenoic acid (DHA) to a malonic acid intermediate which is subsequently reduced to 1,3 propanediol (PD...
PURPOSE: A green and red algae removing apparatus equipped in a vessel is provided to prevent an ecosystem from destroying, and to protect fish and seashells by removing materials which cause the generation of green and red algae. CONSTI... 被引量: 0发表: 0年 ...
3,001, filed in 2006 by Cheul and Goyeneche, describes a cleaning system for aquaculture nets designed to extract algae and incrustations adhering to them. The equipment operates by means of a vacuum device. This vacuum device has a submerged pump that sucks up said biofouling with the aid...
In this environment, these toxic pollutants form parasitic accumulations in almost all marine organisms, especially fish, sponges, algae, plankton, phytoplankton and other types of biota [20,21]. At the same time, much research has been carried out related to the management of toxic pollutants ...
Thiacloprid showed slightly better reductions in all aquatic plant systems, reaching up to 83.3% removal for the hyacinth system, 81.9% for the lemna and azola systems, and 63.8% for the algae control tank. Accordingly, dimethomorph presented reductions from no removal to 82.9% in the water ...
After algae cells die, their biomass decomposes, which releases even larger amounts of phosphorus and nitrogen into the water and additionally deteriorates the oxygen conditions in reservoirs. The lower amount of dissolved oxygen in water increases the release of nutrients from the bottom sediments ...
