In a continuous biogas plant, receiving manure from 200 dairy cows and 400 calves and young stock, survival of salmonellas and Ascaris suum eggs was studied. The bacteria and parasite eggs were kept in filter sacs in the manure that had a temperature of 55 degrees C. No viable salmonellas or Ascaris suum eggs could be found after 24h in the digester. Survival of salmonellas and Ascaris suum eggs was also studied in the manure pit where the manure was stored after digestion. The temperature in the manure pit varied between 22-27 degrees C. Salmonellas survived 35 but not 42 days. On day 56, when the experiments had to be stopped, 60% of the Ascaris eggs were viable.
在一座连续式沼气厂中,研究了接收来自200头奶牛和400头犊牛及幼畜粪便时沙门氏菌和猪蛔虫卵的存活情况。将细菌和寄生虫卵置于温度为55摄氏度的粪便中的滤袋内。在消化池中24小时后未发现有存活的沙门氏菌或猪蛔虫卵。还在消化后粪便储存的粪坑中研究了沙门氏菌和猪蛔虫卵的存活情况。粪坑中的温度在22至27摄氏度之间变化。沙门氏菌存活了35天但未存活42天。在第56天,当实验不得不停止时,60%的蛔虫卵仍具有活力。
