Highlights • Lactic acid bacteria convert sodium selenite into organic selenocysteine and elemental Nano-selenium.• Lactic acid bacteria were selected on their ability to grow in a sodium selenite medium and to convert selenite to organic and Nano-Se.• The ability of lactic acid bacteria to act as silage inoculants was not compromised by the addition of sodium selenite.• Lactic acid bacteria inoculants can convert sodium selenite in silo to supplement livestock with organic and predominately Nano-Se.

评估青贮饲料乳酸菌在实验室规模筒仓内吸收和转化无机硒的能力

亮点 • 乳酸菌将亚硒酸钠转化为有机硒代半胱氨酸和元素纳米硒。• 乳酸菌的选择依据是其在亚硒酸钠培养基中生长以及将亚硒酸钠转化为有机硒和纳米硒的能力。• 乳酸的能力添加亚硒酸钠不会影响细菌作为青贮饲料接种剂的作用。• 乳酸菌接种剂可以在筒仓中转化亚硒酸钠，为牲畜补充有机硒和主要是纳米硒。
