Abstract

This research aimed to produce, on a multigram scale, a new class of non-toxic, halogen- and metal-free antifouling agents from the abundant lecithin byproducts of industrial soybean oil extraction. Three glycerophospholipid analogues were prepared by a facile methanolysis of crude soybean lecithins and a subsequent solvent-free O-alkylation: lysoglycerophosphocholines (LGPCs) and its ether derivatives -alkyl lysoglycerophosphocholines (ALPCs). As efficient antiproliferative agents, LGPCs and ALPCs are an eco-friendly alternative to current commercial antifoulants which possess significant toxicity to aquatic life. immersion tests of coated stainless-steel nets with previously incorporated automotive paint products, LGPCs and ALPCs (1--octadecyl-2--acyl--glycero-3-phosphocholine, ALPC18, and 1--hexadecyl-2--acyl--glycero-3-phosphocholine, ALPC16), in an aquaculture reservoir in SP-Brazil revealed significant growth inhibition against macrofouling species, especially the epibiotic golden mussel (), when compared with the control. These results promise a more sustainable and ecologically innocuous approach to combating the biofouling phenomenon and the deeply concerning dissemination of the golden mussel which has provoked an economic crisis in the energy and aquaculture sectors.

摘要

本研究旨在以多克规模，从工业大豆油提取过程中产生的丰富卵磷脂副产品制备一类新型无毒、无卤素和无金属的防污剂。通过对粗大豆卵磷脂进行简便的甲醇解反应以及随后的无溶剂O-烷基化反应，制备了三种甘油磷脂类似物：溶血甘油磷脂胆碱（LGPCs）及其醚衍生物——烷基溶血甘油磷脂胆碱（ALPCs）。作为高效的抗增殖剂，LGPCs和ALPCs是目前对水生生物具有显著毒性的商业防污剂的环保替代品。在巴西圣保罗的一个水产养殖水库中，对预先掺入汽车漆产品、LGPCs和ALPCs（1-十八烷基-2-酰基-甘油-3-磷酸胆碱，ALPC18，以及1-十六烷基-2-酰基-甘油-3-磷酸胆碱，ALPC16）的涂层不锈钢网进行浸泡测试，结果显示，与对照相比，对大型污损物种，尤其是附生的金贻贝（ ）有显著的生长抑制作用。这些结果为对抗生物污损现象以及令人深感担忧的金贻贝传播提供了一种更可持续且生态无害的方法，金贻贝的传播已在能源和水产养殖部门引发了经济危机。
