本研究旨在评价接种剂对玉米青贮好氧暴露过程中微生物群落和霉菌毒素污染的影响。分别用布氏乳杆菌(Lb，1.0 × 106cfu/g鲜重)、植物乳杆菌(Lp，1.0 × 106cfu/g FW)或LBLP(1.0 × 106cfu/g FW)对感染或不感染产霉真菌的玉米进行青贮。青贮料中醋酸浓度(P<； )显著高于对照(C)和非真菌感染组(P<；LBLP0.05)。真菌感染引起玉米赤霉烯酮(Zen，P= 0.0 1)、伏马菌素B1(FUB1，P= 0.0 2)和伏马菌素B2(FUB2，P= 0.0 2)的增加。NFI青贮料中异链孢子菌的相对丰度(RA)高于普通青贮料(P<； 0.001)，而哈萨克斯坦菌(P<； 0.001)、酵母菌(P= 0.047)和念珠菌(P= 0.025)的相对丰度低于普通青贮料。与NFI青贮料C相比，添加LBLP和LBLP提高了青贮料的有氧稳定性。LBLP和LBLP有可能改善非真菌感染的玉米青贮料的有氧稳定性和减轻真菌毒素污染。
This study aimed to evaluate the effects of inoculants on the microbial community and mycotoxins contamination of corn silage during aerobic exposure. Whole-crop corn infected with or without mycotoxigenic fungi were ensiled withLentilactobacillus buchneri(LB, 1.0 × 106cfu/g fresh weight (FW)),Lactiplantibacillus plantarum(LP, 1.0 × 106cfu/g FW), or LBLP at 1.0 × 106cfu/g FW each. The concentration of acetic acid (AcA) (P< 0.05) in LB and LBLP silages was higher than in control (C) and LP of non-fungal infection (NFI) silages. The fungal infection resulted in a larger increase of zearalenone (ZEN,P= 0.01), fumonisin B1(FUB1,P= 0.02), and fumonisin B2(FUB2,P= 0.02). The relative abundance (RA) ofIssatchenkiain NFI was higher (P< 0.001) than FI silages, whereas the RA ofKazachstania(P< 0.001),Zygosaccharomyces(P= 0.047), andCandida(P= 0.025) in NFI were lower than these of FI silages. The aerobic stability was improved by the application of LB and LBLP as compared with the C of NFI silages. The LB and LBLP had the potential to improve aerobic stability and alleviate mycotoxins contamination of non-fungal infected corn silages.Graphical Abstract
