Abstract

Dimethylsulfoniopropionate (DMSP) is a plentiful organic sulfur metabolite and the primary precursor for dimethyl sulfide (DMS), which plays a crucial role in global sulfur cycling, the formation of clouds, and cooling the warming earth. The origin and fate of DMSP are intricately linked to marine microorganisms, making the variation of the microorganism community crucial for DMSP dynamics. Nonetheless, the impact of pervasive marine microplastics on microorganisms and processes related to DMSP synthesis and degradation remains insufficiently investigated. To bridge this gap, a 14‐d deck‐based microcosm experiment was conducted, revealing that microplastics significantly altered the composition of microorganism communities and dramatically inhibited the release of DMS and DMSP. Furthermore, multivariate analysis demonstrated that the variations both in environmental variables and microorganism communities caused by microplastics were forcing factors in reducing DMS and DMSP release. In addition, the predicted function of the bacterial community showed a significant reduction in the presence of dddP and dmdA genes when exposed to microplastics, which directly disrupted both the demethylation and cleavage pathways of DMSP. These results indicate that the release of DMS and DMSP in marine ecosystems can be significantly affected by microplastics through influencing microorganisms. Thus, it is imperative to conduct research on controlling the synthesis and degradation of DMSP in the ocean, particularly in response to these environmental pollution issues. Such research can help discern new patterns from specific phenomena and identify crucial processes.

微塑料压力改变微生物群落结构并减少生物二甲基硫化合物的产生
二甲基硫代丙酸酯(DMSP)是一种丰富的有机硫代谢物,也是二甲基硫醚(DMS)的主要前体,在全球硫循环、云的形成和冷却变暖的地球方面发挥着至关重要的作用。DMSP 的起源和归宿与海洋微生物密切相关,因此微生物群落的变化对 DMSP 的动态变化至关重要。然而,普遍存在的海洋微塑料对微生物以及与 DMSP 合成和降解相关的过程的影响仍未得到充分研究。为了填补这一空白,我们进行了一项为期 14 天的甲板微生态系统实验,结果表明,微塑料显著改变了微生物群落的组成,并极大地抑制了 DMS 和 DMSP 的释放。此外,多变量分析表明,微塑料引起的环境变量和微生物群落的变化是减少 DMS 和 DMSP 释放的强制因素。此外,细菌群落的预测功能表明,当暴露于微塑料中时,dddP 和 dmdA 基因的存在显著减少,这直接破坏了 DMSP 的去甲基化和裂解途径。这些结果表明,海洋生态系统中 DMS 和 DMSP 的释放会受到微塑料通过影响微生物而产生的重大影响。因此,当务之急是研究如何控制海洋中 DMSP 的合成和降解,尤其是针对这些环境污染问题。此类研究有助于从特定现象中发现新的模式,并确定关键过程。

期刊介绍: Limnology and Oceanography (L&O; print ISSN 0024-3590, online ISSN 1939-5590) publishes original articles, including scholarly reviews, about all aspects of limnology and oceanography. The journal''s unifying theme is the understanding of aquatic systems. Submissions are judged on the originality of their data, interpretations, and ideas, and on the degree to which they can be generalized beyond the particular aquatic system examined. Laboratory and modeling studies must demonstrate relevance to field environments; typically this means that they are bolstered by substantial "real-world" data. Few purely theoretical or purely empirical papers are accepted for review.
