Synergistic enhancement of Sorghum bicolor nutrient uptake and growth by microbiomes in enhanced biological phosphorus removal system and arbuscular mycorrhizal fungi.

ABSTRACT:

Background

Understanding soil microbial interactions is essential for developing biofertilizers in regenerative agriculture. Polyphosphate-accumulating organisms (PAOs) play a pivotal role in enhanced biological phosphorus removal (EBPR) systems by sequestering phosphorus from wastewater and storing it as intracellular polyphosphate. However, their role in terrestrial phosphorus cycling remains poorly characterized, despite their potential to serve as a reservoir of plant-available phosphorus. This study investigates PAO-enriched microbiomes in the sorghum rhizosphere, focusing on their novel interactions with arbuscular mycorrhizal fungi (AMF). By integrating PAOs derived from EBPR biosolids and compost with AMF, we assessed their synergistic effects on plant growth and nutrient u
