The use of the cold-tolerant bacterial consortium PSBC can accelerate the decomposition of cornstalks, increase organic matter, phosphorus, and potassium in the soil, and alter microbial community diversity to benefit cornstalk degradation.
To explore an effective approach for accelerating cornstalk decomposition and return under low temperature, nine psychrotrophic cellulose-, hemicellulose-, and lignin-degrading bacterial strains were used with biochar as the carrier to prepare a novel psychrotrophic stalk-degrading bacterial consortium (PSBC). With PSBC, the maximum cornstalk degradation rate reached 59.3% after 50 d at 10-15 degrees C, which accelerated cornstalk decomposition, resulting in increases in organic matter, phosphorus, and potassium in the soil. Microbial community analysis demonstrated that PSBC enhanced microbial community diversity and altered specific selection. Genera Arthrobacter, Pseudomonas, and Pantoea in PSBC became dominant in the soil microbiota, which benefited cornstalk degradation. Therefore, this work provides a promising strategy to facilitate the degradation of cornstalks in cold regions, which has potential application value for carbon neutrality.
