摘要

人工鱼礁是振兴沿海和海洋生态系统的有用工具。它们的配方决定了生物膜的形成,而生物膜是海洋微生物和大型生物定殖过程的先决条件。与混凝土相比,生物基聚合物具有更好的特性,包括结构、配方、凹凸度和可回收性。本文旨在探索一种新的人工鱼礁,这种鱼礁由高含量(30%)亚麻纤维(Linum utilatissimum)增强的生物复合材料制成。使用两种海洋微生物对细胞粘附和由此形成的生物膜进行了评估:3J6 和 Cylindrotheca closterium。此外,还评估了亚麻纤维浸出物和塑料单体对这些海洋微生物生长的影响。结果表明,在聚合物基质中引入亚麻纤维可改变其物理化学特性,从而根据微生物的不同调节粘附性和生物膜的形成。这项研究为进一步开发由生物复合材料制成的新型功能化人工鱼礁提供了启示。

Marine biofilm formation on flax fibre reinforced biocomposites.

Artificial reefs represent useful tools to revitalize coastal and ocean ecosystems. Their formulation determines the biofilm formation which is the prerequisite for the colonization process by marine micro- and macroorganisms. In comparison with concrete, biobased polymers offer improved characteristics, including architecture, formulation, rugosity and recycling. This article aims to explore a new scale of artificial reef made of biocomposites reinforced with a high flax fibre (Linum utilatissimum) content (30%). Cellular adhesion and resulting biofilm formation were assessed using two marine microorganisms: Pseudoalteromonas sp. 3J6 and Cylindrotheca closterium. The influence of flax fibre leachates and plastic monomers on the growth of those marine microorganisms were also evaluated. Results indicated that the introduction of flax fibres inside the polymer matrix modified its physicochemical properties thus modulating adhesion and biofilm formation depending on the microorganism. This study gives insights for further developments of novel functionalized artificial reefs made of biocomposites.

期刊介绍: Biofouling is an international, peer-reviewed, multi-discliplinary journal which publishes original articles and mini-reviews and provides a forum for publication of pure and applied work on protein, microbial, fungal, plant and animal fouling and its control, as well as studies of all kinds on biofilms and bioadhesion. Papers may be based on studies relating to characterisation, attachment, growth and control on any natural (living) or man-made surface in the freshwater, marine or aerial environments, including fouling, biofilms and bioadhesion in the medical, dental, and industrial context. Specific areas of interest include antifouling technologies and coatings including transmission of invasive species, antimicrobial agents, biological interfaces, biomaterials, microbiologically influenced corrosion, membrane biofouling, food industry biofilms, biofilm based diseases and indwelling biomedical devices as substrata for fouling and biofilm growth, including papers based on clinically-relevant work using models that mimic the realistic environment in which they are intended to be used.
