The Soil Ecosystem02:23

The Soil Ecosystem

19.6K
Plants obtain inorganic minerals and water from the soil, which acts as a natural medium for land plants. The composition and quality of soil depend not only on the chemical constituents but also on the presence of living organisms. In general, soils contain three major components:

Surface Membrane Barriers01:18

Surface Membrane Barriers

1.1K
The skin and mucous membranes serve as the primary line of defense against pathogens by providing both physical and chemical protection. These barriers are essential in preventing the entry and establishment of microbes, thereby maintaining the integrity of the host.
The outer layer of the skin, the epidermis, is a robust barrier comprising layers of closely packed keratinized cells. This dense arrangement prevents microbes from penetrating the body. The periodic shedding of epidermal cells...

主要方法:

  • 用沉浸试验 (DIN EN 16105) 和自然气候变化生成了外墙化物.
  • 土壤微观世界用酸盐处理,并化29天.
  • 使用基因测序 (ITS和16SrRNA) 分析了活跃和总的土壤微生物群落,此后对活跃细胞进行氧氨标记.

主要成果:

  • 立面化物显著减少了细菌和真菌的总基因拷贝数.
  • 活跃的细菌和真菌丰富度下降,社区组成与总社区相比发生了变化.
  • 没有生物制剂的立面的化物影响了土壤微生物群落,与具有生物制剂的微生物群落一样.
  • 特定的活性微生物成员被确定为受益于或被化物暴露所抑制.

结论:

  • 立面化物显然改变了土壤微生物群落的结构和功能.
  • 生物制剂在建筑材料中的存在不仅仅决定了对土壤微生物的生态毒理影响.
  • 漏方法也影响了效果,突出了生物制剂环境命运的复杂性.
