The discharge of industrial effluent creates environmental problems around the world and so necessitates the need for the economically expensive and sometimes technically problematic treatment of the wastewater. Laccases have enormous potential for the oxidative bioremediation of toxic xenobiotic compounds using only molecular oxygen as the sole cofactor for their reaction, and their application is regarded as environmentally friendly. Due to the low substrate specificity of laccases, they can oxidize a variety of substrates. Moreover, by using appropriate mediators, laccases can degrade a wide range of substrates, including those with structural complexity. Thus, laccases are an attractive alternative for wastewater treatment. Marine environments are rich in microorganisms that are exposed to extreme conditions, such as salinity, temperature, and pressure. Laccases from these microorganisms potentially have suitable properties that might be adaptive to bioremediation processes. This review provides the latest information on laccases from marine environments, their sources, biochemical properties, media composition for laccase production, and their applications in the bioremediation of industrial waste, especially focusing on dye decolorization.
工业废水的排放给全世界带来了环境问题，因此需要对废水进行经济上昂贵且有时在技术上有问题的处理。漆酶具有仅使用分子氧作为其反应唯一辅助因子对有毒异生物质化合物进行氧化生物修复的巨大潜力，并且其应用被认为是环保的。由于漆酶的底物特异性低，它们可以氧化多种底物。此外，通过使用适当的介体，漆酶可以降解包括具有结构复杂性的多种底物。因此，漆酶是废水处理的一种有吸引力的替代方法。海洋环境中富含微生物，这些微生物暴露在盐度、温度和压力等极端条件下。这些微生物来源的漆酶可能具有适合生物修复过程的特性。本综述提供了海洋环境中漆酶的最新信息，包括其来源、生化特性、漆酶生产的培养基组成以及它们在工业废物生物修复中的应用，特别是重点介绍了染料脱色。
