Phosphate-solubilizing and polymerizing bacteria enhance phosphorus availability and growth of rice.

ABSTRACT:

Introduction

Phosphorus (P) is a limiting nutrient in soil-plant nutrient cycling, functional microorganisms can promote P transformation. While previous studies have mainly focused on either phosphorus solubilization or phosphorus aggregation by bacterial strains, few address both aspects simultaneously.

Methods

In this study, we screened Acinetobacter johnsonii (NHP4a-2) and Pseudomonas glycinae (NHP4b-2) strains, both of which can effectively solubilize and polymerize P. Their performance was evaluated by measuring phosphate solubilization capacity, polyphosphate accumulation levels, and the activity of related enzymes (polyphosphate kinase, extrapolyphosphatase, and glucose dehydrogenase). A high-phosphorus/low-phosphorus alternating culture system was employed to simula
