|Title||Changes in Structural and Functional Responses of Bacterial Communities under Different Levels of Long-Term Compost Application in Paddy Soils|
J. Microbiol. Biotechnol.2019 ;
|Abstract||Soils amended for long-term with high levels of compost demonstrated greater abundance of
bacterial members of the phylum Bacteroidetes whereas a decreasing trend in the relative
abundance of phylum Acidobacteria was noted with increasing levels of compost. Metabolic
profiles predicted by PICRUSt demonstrated differences in functional responses of the
bacterial community according to the treatments. Soils amended with lower compost levels
were characterized by abundance of genes encoding enzymes contributing to membrane
transport and cell growth whereas genes encoding enzymes related to protein folding and
transcription were enriched in soils amended with high levels of compost. Thus, the results of
the current study provide extensive evidence of the influence of different compost levels on
bacterial diversity and community structure in paddy soils.|
