Abstract

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.

土壤生物薄膜微生物群落的季节性变化
使用玻璃纤维过滤器作为诱捕材料,在一年中的不同时间(1 月、4 月、7 月、9 月)浸入田间土壤,并在其中培养不同时期(3 个月、6 个月、9 个月、12 个月),对生物膜和浮游原核生物群落进行了研究。生物膜和浮游生物群落的组成随着时间的推移而波动,这可能是由演替过程和不同的环境因素决定的。这突出表明,土壤生物膜是一种动态结构,其微生物群落与土壤浮游生物群落不同。此外,生物膜与浮游生物 16S rRNA 基因拷贝数比的量化结果表明,土壤原核生物主要以生物膜成分出现。
