【摘要】：为调查收割至青贮装填前乳酸菌的动态变化,本研究以甜玉米(Zea mays L.)和热研四号(Pennisetum purpureum×P.americanum‘Reyan No.4’)王草为材料,检测从刈割、切短、放置8h和放置24h四个阶段乳酸菌的动态变化。研究结果表明:从未切短(4.25lg cfu·g~(-1) FM)到切短(5.69lg cfu·g~(-1) FM)阶段乳酸菌的数量显著增加(P0.05),主要是乳酸乳球菌(Lactococcus lactic)、柠檬明串珠菌(Leuconostoc citreum)和融合魏斯氏菌(Weissella confuse)。随着放置时间的延长,乳酸菌种类变化随植物品种而异,甜玉米切短后发现柠檬明串珠菌,放置24h后发现假肠膜明串珠菌(Leuconostoc pseudomesenteroides),而热研四号王草切短后菌株短乳杆菌(Lactobacillus brevis)消失。
[Abstract]:In order to investigate the dynamic changes of lactic acid bacteria before harvesting to silage, sweet corn (Zea mays L.) was used in this study. The dynamic changes of lactic acid bacteria (Lactic acid bacteria) in the four stages of cutting, storing for 8 hours and 24 hours were detected by using Heyan No. 4 (Pennisetum purpureum 脳 P.americanum'Reyan No.4' as the material. The results showed that the number of lactic acid bacteria (lactic acid bacteria) in 5.69lg cfu g ~ (-1) FM) (4.25lg cfu g-1) FM) increased significantly (P0.05), mainly Lactococcus lactis (Lactococcus lactic),. (Leuconostoc citreum) and (Weissella confuse). Fusion of Streptococcus lemonii The species of lactic acid bacteria varied with plant varieties with the prolonging of storage time, and (Leuconostoc pseudomesenteroides), was found after cut short of sweet corn and 24 hours later. But the (Lactobacillus brevis) of Lactobacillus brevis disappeared after cutting short.
