16S Regional variation in Swedish acid sulfate soil microbial communities
This study investigated 20 active acid sulfate soils (field pH less than 4.0) collected throughout Sweden and tested for microbial community composition using 16S rRNA gene amplicons. Analysis of the microbial community compositions identified a north (boreal zone) to south (hemiboreal zone) regional divide, primarily within the oxidized zone, to a lesser degree in the transition zone, while little differences were observed in the reduced zone.
