使用石油衍生的塑料对环境问题做出了重大贡献,例如温室气体排放和生态系统中塑料废物的积累。研究人员一直致力于开发环保聚合物作为传统塑料的替代品,以解决这些问题。这篇综述提供了中链长度聚羟基链烷酸酯(mcl-PHAs)的全面概述,由微生物产生的可生物降解的生物聚合物有望替代传统塑料。评论讨论了分类,属性,以及研究较少的mcl-PHA的潜在底物,与聚(3-羟基丁酸酯)相比,突出了它们更大的延展性和灵活性,一个众所周知但脆弱的PHA。作者总结了现有的研究,强调了mcl-PHAs在生物医学中的潜在应用。包装,生物复合材料,水处理,和能量。未来的研究应该集中在改进生产技术上,确保经济可行性,并解决与工业实施相关的挑战。研究生物降解性,稳定性,机械性能,耐用性,与基于石油的产品相比,基于mcl-PHA的产品的成本效益至关重要。mcl-PHA的未来看起来很有希望,随着预计将优化生产技术的持续研究,增强材料性能,并扩展应用。微生物学家之间的跨学科合作,工程师,化学家,和材料科学家将推动这一领域的进步。总之,这篇综述是理解mcl-PHA作为传统塑料的可持续替代品的宝贵资源。然而,需要进一步的研究来优化生产方法,评估长期生态影响,并评估各行业的可行性和可行性。
Using petroleum-derived plastics has contributed significantly to environmental issues, such as greenhouse gas emissions and the accumulation of plastic waste in ecosystems. Researchers have focused on developing ecofriendly polymers as alternatives to traditional plastics to address these concerns. This
review provides a comprehensive overview of medium-chain-length
polyhydroxyalkanoates (mcl-PHAs), biodegradable biopolymers produced by microorganisms that show promise in replacing conventional plastics. The
review discusses the classification, properties, and potential substrates of less studied mcl-PHAs, highlighting their greater ductility and flexibility compared to poly(3-hydroxybutyrate), a well-known but brittle PHA. The authors summarize existing research to emphasize the potential applications of mcl-PHAs in biomedicine, packaging, biocomposites, water treatment, and energy. Future research should focus on improving production techniques, ensuring economic viability, and addressing challenges associated with industrial implementation. Investigating the biodegradability, stability, mechanical properties, durability, and cost-effectiveness of mcl-PHA-based products compared to petroleum-based counterparts is crucial. The future of mcl-PHAs looks promising, with continued research expected to optimize production techniques, enhance material properties, and expand applications. Interdisciplinary collaborations among microbiologists, engineers, chemists, and materials scientists will drive progress in this field. In conclusion, this
review serves as a valuable resource to understand mcl-PHAs as sustainable alternatives to conventional plastics. However, further research is needed to optimize production methods, evaluate long-term ecological impacts, and assess the feasibility and viability in various industries.
