近几十年来,藻类已被证明是具有生物活性的不同生物活性化合物的来源,这增加了这些生物在食品中的潜在应用,化妆品,Pharmaceutical,动物饲料,和其他工业部门。另一方面,人们对开发控制和/或根除入侵藻类的有效策略越来越感兴趣,因为它们对海洋生态系统和受影响区域的经济具有负面影响。然而,控制措施的应用通常消耗时间和资源,并且无利可图。考虑到这种情况,将入侵藻类物种作为工业应用的生物活性化合物来源的价值化可能是减少其种群的合适策略,同时获得环境和经济效益。为了进行这种实践,有必要评估藻类的化学和营养成分以及提取目标化合物的最有效方法。在西班牙西北部,五种藻类被认为是侵入性的:阿玛塔,钴易碎,龙须草,马尾藻,还有Grateulopiaturuturu.这篇综述简要介绍了它们的主要生物活性化合物,生物活动,和用于回收的提取系统。此外,收集了它们有益特性的证据以及将它们用作水产养殖动物饮食中的补充剂的可能性,以说明它们可能的应用之一。
In the recent decades, algae have proven to be a source of different bioactive compounds with biological activities, which has increased the potential application of these organisms in food, cosmetic, pharmaceutical, animal feed, and other industrial sectors. On the other hand, there is a growing interest in developing effective strategies for control and/or eradication of invasive algae since they have a negative impact on marine ecosystems and in the economy of the affected zones. However, the application of control measures is usually time and resource-consuming and not profitable. Considering this context, the valorization of invasive algae species as a source of bioactive compounds for industrial applications could be a suitable strategy to reduce their population, obtaining both environmental and economic benefits. To carry out this practice, it is necessary to evaluate the chemical and the nutritional composition of the algae as well as the most efficient methods of extracting the compounds of interest. In the
case of northwest Spain, five algae species are considered invasive: Asparagopsis armata, Codium fragile, Gracilaria vermiculophylla, Sargassum muticum, and Grateulopia turuturu. This review presents a brief description of their main bioactive compounds, biological activities, and extraction systems employed for their recovery. In addition, evidence of their beneficial properties and the possibility of use them as supplement in diets of aquaculture animals was collected to illustrate one of their possible applications.
