海洋生物学
生物矿物化
斯克拉克提尼珊瑚

背景情况:

岩石珊瑚骨架的形成过程 (化) 尚不完全理解.
存在两个主要假设:物理化学过程与生物介导的过程.

研究的目的:

研究石珊瑚中石灰岩骨架的形成机制.
要确定化主要是物理化学还是生物驱动的.

主要方法:

使用超高分辨率的三维成像.
使用二维固态核磁共振 (NMR) 光谱.

主要成果:

矿物沉积是生物驱动的, 而不是纯粹的物理化学.
无形纳米粒子聚合在有机丰富的微环境中.
通过粒子附着和晶体生长形成有序的阿拉戈尼特结构.

Biological Methods for Microbial Control

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...
