Abstract

Marine biomass including fishery products are precious protein resources for human foods and are an alternative to livestock animals in order to reduce the virtual water problem. However, a large amount of marine waste can be generated from fishery products and it is not currently recycled. We evaluated the metabolism of digested marine waste using integrated analytical methods, under anaerobic conditions and the fertilization of abandoned agricultural soils. Dynamics of fish waste digestion revealed that samples of meat and bony parts had similar dynamics under anaerobic conditions in spite of large chemical variations in input marine wastes. Abandoned agricultural soils fertilized with fish waste accumulated some amino acids derived from fish waste, and accumulation of l-arginine and l-glutamine were higher in plant seedlings. Therefore, we have proposed an analytical method to visualize metabolic dynamics for recycling of fishery waste processes.

摘要

包括渔业产品在内的海洋生物量是人类食物中宝贵的蛋白质资源，并且是家畜动物的替代品，以减少虚拟水问题。然而，渔业产品会产生大量海洋废弃物，目前尚未进行回收利用。我们使用综合分析方法，在厌氧条件下以及废弃农业土壤施肥的情况下，评估了消化后的海洋废弃物的代谢情况。鱼类废弃物消化动态表明，尽管输入的海洋废弃物在化学组成上存在很大差异，但肉和骨部分的样品在厌氧条件下具有相似的动态。用鱼类废弃物施肥的废弃农业土壤积累了一些源自鱼类废弃物的氨基酸，植物幼苗中L-精氨酸和L-谷氨酰胺的积累量更高。因此，我们提出了一种分析方法，以可视化渔业废弃物回收过程中的代谢动态。
