Microbial communities harbouring the alkaline phosphatase (ALP) <i>phoD</i> gene (<i>phoD</i>-harboring bacteria community, hereafter) play the key roles in the regulation of P availability in soils. Nevertheless, the consequences of oil contamination on ALP activity and <i>phoD</i>-harboring bacterial community dynamics are poorly understood. It is necessary to assess <i>phoD</i>-harboring bacterial abundance, community diversity, and ALP activity in response to oil contamination. This information would be useful for formulating plans for future bioremediation processes.<h4>Methods</h4>In this study, we sampled the contaminated and uncontaFrontiers in microbiology1732638https://www.ebi.ac.uk/biostudies/studies/S-EPMC12835899biostudies-literatureMain controls on <i>phoD</i>-harboring bacterial community abundance, composition, and activity from oil-contaminated soils at the Changqing oilfield, Northwest China.PMC12835899Chu QLi XZheng JQiu WWang QLi DZhang XZhang HDu XfalseMain controls on <i>phoD</i>-harboring bacterial community abundance, composition, and activity from oil-contaminated soils at the Changqing oilfield, Northwest China.<h4>Background</h4>Soil phosphorus (p) availability limits the native microbial activity, which then inhibits the petroleum hydrocarbon biodegradation.
