查询词典 lactic acid

Finally, the pH value, lactic acid, water soluble carbohydrate, ammonia nitrogen and cellulose contents were determined for WH silage prepared under the suitable adding doses of lactobacillus and cellulase at day 1, 3, 5, 15, 25, 35 after ensilaging. The pH value decreased from 5.5 before ensiling to 4.3 on the 35th ensiling day, whereas the reverse change tendence was observed for lactic acid content. The cellulose content of silage was lower from 26.5%DM in raw material to 22.3%DM.

结果表明：pH值由青贮前的5.5至青贮第35天时降至稳定的状态，而乳酸含量的变化趋势相反；凤眼莲茎叶纤维素含量从未青贮前的26.5%干物质，至青贮第35天降至22.3%干物质，降低了约4个百分点；青贮料中可溶性碳水化合物的含量随青贮时间的延长而逐渐下降，但是在第5天到第15天的时间段里，可溶性碳水化合物的含量无显著性下降；氨态氮占总氮的比例从青贮第1天的4.61%显著上升至第5天的8.25%，而从第5天开始到第35天，氨态氮占总氮的比例上升的幅度较小。

All additions rapidly decreased silage pH under different DM contents of M.sativa.M.sativa(DM 38.45%) ensiled with lactic acid bacteria+cellulase gave the best results: ammonia nitrogen content was reduced,and most CP was conserved and most lactic acid produced.

结果表明，不同干物质含量的苜蓿青贮时，乳酸菌+纤维素酶的添加均能使青贮pH值快速下降；苜蓿半干青贮(干物质含量为38.45%)可使青贮氨态氮含量显著降低，并保存有较多的粗蛋白质，生成较多乳酸，其中以添加乳酸菌106 cfu/g+纤维素酶0.05 g/kg的青贮效果最好，其青贮综合评定得分最高，达93分。
