Exploitation of marine fishes is the main source of several life-supporting feed compounds such as proteins, lipids, and carbohydrates that maintain the production of most trading marine organisms by aquaculture. However, at this rate the marine inventory will go to the end soon, since fishery resources are finite. In this sense, the availability of the principal ingredients obtained from marine fishes is going to decrease considerably, increasing the diet prices and affecting the economy of this activity. Therefore, aquaculture industry needs to find nonexpensive land unconventional resources of protein, carbohydrates, and lipids and use bacterial probiotics to improve digestion-assimilation of these unfamiliar compounds. Bacillus subtilis is a cosmopolitan probiotic bacterium with a great enzymatic profile that could improve nutrient digestion-assimilation, induce healthy growth, and avoid water pollution, decreasing economic problems and increasing yields in the aquaculture industry. In this chapter, we present how Bacillus enzymes can help marine animals to assimilate nutrients from unconventional and economic plant resources.
海洋鱼类的开发是多种维持生命的饲料化合物的主要来源，如蛋白质、脂质和碳水化合物，这些化合物维持着水产养殖中大多数商业海洋生物的产量。然而，按照这个速度，海洋资源很快就会枯竭，因为渔业资源是有限的。从这个意义上说，从海洋鱼类中获取的主要成分的可用性将大幅下降，从而提高饲料价格并影响该行业的经济。因此，水产养殖业需要找到廉价的陆地非传统蛋白质、碳水化合物和脂质资源，并使用益生菌来改善这些不熟悉化合物的消化吸收。枯草芽孢杆菌是一种具有广泛酶谱的世界性益生菌，它可以改善营养物质的消化吸收，促进健康生长，避免水污染，减少经济问题并提高水产养殖业的产量。在本章中，我们将介绍枯草芽孢杆菌的酶如何帮助海洋动物从非传统且经济的植物资源中吸收营养。
