    Deciphering Heat Stress Mechanisms and Developing Mitigation Strategies in Dairy Cattle: A Multi-Omics Perspective

    Deciphering Heat Stress Mechanisms and Developing Mitigation Strategies in Dairy Cattle: A Multi-Omics Perspective by Zhiyi Xiong, Lin Li, Kehui Ouyang, Mingren Qu, Qinghua Qiu

    Published 2025-07-01

    Heat stress (HS) in dairy cattle triggers systemic physiological disruptions, including milk yield decline, immune suppression, and reproductive dysfunction, jeopardizing sustainable livestock production. While conventional single-omics or phenotypic studies have provided fragmented insights, they f...

    Characterization of Cellulase from the Rumen Metagenome and Evaluation of its Hydrolytic Potential for Agricultural Wastes

    Characterization of Cellulase from the Rumen Metagenome and Evaluation of its Hydrolytic Potential for Agricultural Wastes by Meng Ouyang, Chanjuan Liu, Ping Sheng, Qinghua Qiu, Kehui Ouyang, Yanjiao Li, Yitian Zang, Xianghui Zhao

    Published 2025-06-01

    The cellulase RuCel224, derived from the rumen metagenome, was successfully expressed in Escherichia coli BL21(DE3), with a molecular weight of ~43 kDa, as confirmed by sulfate-polyacrylamide gel electrophoresis (SDS-PAGE) analysis. Substrate specificity assays revealed the highest activity against...
