概括
这项研究检查了以减少鱼粉和鱼油的饮食养稀缺鱼的肠道微生物群. 低丰度的细菌,而不是整体多样性,显示了与水产养殖饮食中的营养挑战相关的变化.
科学领域:
- 水产养殖营养和鱼类健康
- 肠道微生物群分析
- 海洋鱼类研究研究
背景情况:
- 肠道微生物群对于鱼类的健康,免疫和营养至关重要,使其成为水产养殖的一个关键研究领域.
- 了解肠道微生物的转变对于评估鱼类的健康和营养状况至关重要,特别是对于替代性料成分.
研究的目的:
- 在不同的食鱼粉 (FM) 和鱼油 (FO) 含量下,鉴定幼 (Argyrosomus regius) 的肠道微生物群的特征.
- 确定特定的微生物特征,与植物性饮食在水产养殖中引发的营养挑战相关.
主要方法:
- 在7周的时间里,青少年被食控制 (CTRL),低 (CD) 和极低 (ED) FM/FO饮食.
- 使用下一代测序来分析肠道粘膜和消化肠道微生物群的组成.
- 统计分析的重点是确定微生物种群丰度的显著差异.
主要成果:
- 在饮食组之间没有发现整体肠道微生物多样性 (α和β) 的显著差异.
- 细菌系Firmicutes,特别是Bacilli,主导了所有样本.
- 在养减少FM/FO饮食的鱼类中,观察到低丰度类型 (Thermoactinomycetales,Kroppenstedtia,Pseudogracilibacillus) 的显著增加.
结论:
- 微小的肠道微生物群多样性对鱼粉和鱼油的显著减少具有弹性.
- 低丰度的细菌种群可以作为水产养殖中营养挑战的敏感指标或生物标志物.
- 针对特定的低丰度微生物可以帮助制定养殖鱼的肠道健康监测策略.

The Roles of Bacteria and Fungi in Plant Nutrition
47.5K
Plants have the impressive ability to create their own food through photosynthesis. However, plants often require assistance from organisms in the soil to acquire the nutrients they need to function correctly. Both bacteria and fungi have evolved symbiotic relationships with plants that help the species to thrive in a wide variety of environments.

Key Elements for Plant Nutrition
24.4K
Like all living organisms, plants require organic and inorganic nutrients to survive, reproduce, grow and maintain homeostasis. To identify nutrients that are essential for plant functioning, researchers have leveraged a technique called hydroponics. In hydroponic culture systems, plants are grown—without soil—in water-based solutions containing nutrients. At least 17 nutrients have been identified as essential elements required by plants. Plants acquire these elements from the...

Photoreceptors and Plant Responses to Light
28.6K
Light plays a significant role in regulating the growth and development of plants. In addition to providing energy for photosynthesis, light provides other important cues to regulate a range of developmental and physiological responses in plants.

Plant Cells and Tissues
65.9K
Plant tissues are collections of similar cells performing related functions. Different plant tissues will have their own specialized roles and can be combined with other tissues to form organs such as flowers, fruit, stem, and leaves. Two major types of plant tissue include meristematic and permanent tissue.

Crop cultivation has a long history in human civilization, with records showing the cultivation of cereal plants beginning at around 8000 BC. This early plant breeding was developed primarily to provide a steady supply of food.

Plant Hormones
27.7K
Plant hormones—or phytohormones—are chemical molecules that modulate one or more physiological processes of a plant. In animals, hormones are often produced in specific glands and circulated via the circulatory system. However, plants lack hormone-producing glands.
