概括
提供安全,营养丰富的乳制品替代品. 尽管牛奶酸奶中微生物数量较高,但老虎坚果酸奶 (TMYS,TMYNS) 缺乏牛奶酸奶中有害的大肠杆菌.
科学领域:
- 食品科学
- 微生物学
- 营养科学
背景情况:
- 由于乳糖不耐受和过敏,对植物乳制品替代品的需求不断增加.
- 关注未充分利用的作物,如老虎坚果 (Cyperus esculentus) 作为新的食物来源.
- 需要安全且营养丰富的非乳制品酸奶选择.
研究的目的:
- 评估老虎坚果酸奶的物理化学,微生物和组成特性.
- 为了比较老虎坚果酸奶 (有或没有初始培养) 和传统牛奶酸奶.
- 通过使用不同的发酵方法,评估老虎坚果作为功能性酸奶基础.
主要方法:
- 虎酸奶 (TMYS,TMYNS) 和牛奶酸奶 (CMY) 的比较分析
- 评价pH值,脂肪含量,可溶性固体总量和微生物负荷.
- 微生物分析包括对大肠杆菌,酵母菌,大肠杆菌和菌的检测.
主要成果:
- 虎酸奶的脂肪含量高于CMY (1.79%-1.88%).
- 与CMY (pH 4. 87) 相比,TMYNS的酸度更高.
- 大肠杆菌不在虎酸奶中,尽管总微生物负载较高 (高达1.1 × 10^5 CFU/mL).
结论:
- 虎是一种安全且营养丰富的非乳制品替代品.
- 虎酸奶中没有大肠杆菌,这表明微生物安全性得到了提高.
- 需要进一步研究以优化传感属性和商业可行性.

The Roles of Bacteria and Fungi in Plant Nutrition
40.8K
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
21.2K
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...

Organisms exhibit remarkable metabolic diversity, categorized based on how they acquire energy and carbon. These strategies enable survival in various ecological niches and are essential for maintaining energy flow and nutrient cycling within ecosystems.Energy and Carbon SourcesOrganisms are classified as phototrophs or chemotrophs based on energy acquisition. Phototrophs use light as their energy source, while chemotrophs rely on oxidizing chemical compounds. Further differentiation arises...

Biological agents offer an effective means of controlling microbial growth by leveraging natural processes like predation, competition, and the secretion of antimicrobial substances.Predatory bacteria such as Bdellovibrio species target and kill pathogens like Salmonella and E. coli. They are widely used in poultry farms to control infections. Myxococcus species help combat plant-pathogenic fungi. These naturally occurring predators serve as eco-friendly alternatives to chemical pesticides and...
