Biofilm and planktonic prokaryotic communities were studied using a glass fibre filter as trapping material immersed in field soil at different times of the year (January, April, July, September) and incubated there for different periods (3, 6, 9, 12 months). The composition of biofilm and planktonic communities fluctuated over time, likely shaped by succession processes and varying environmental factors. This highlights soil biofilms as dynamic structures whose microbial community differs from that of soil plankton. Additionally, quantification of the biofilm-to-plankton 16S rRNA gene copy number ratio indicated that soil prokaryotes occur mainly as biofilm components.

土壤生物膜微生物群落的季节变化


使用玻璃纤维过滤器作为捕获材料，在一年中的不同时间（一月、四月、七月、九月）浸入田间土壤中，并在那里培养不同时期（3、6、9、12 个月），对生物膜和浮游原核生物群落进行研究。生物膜和浮游群落的组成随着时间的推移而波动，可能是由演替过程和不同的环境因素决定的。这凸显了土壤生物膜作为动态结构，其微生物群落不同于土壤浮游生物。此外，生物膜与浮游生物 16S rRNA 基因拷贝数比率的量化表明土壤原核生物主要作为生物膜成分出现。
