Effect of lactid acid bacteria inoculants, formic acid, potassium sorbate and sodium benzoate on fermentation quality and aerobic stability of wilted grass silage Organic Eprints
Saarisalo, Eeva; Jalava, Taina; Skyttä, Eija; Haikara, Auli; Jaakkola, Seija.
The efficiency of a novel strain of lactic acid bacteria inoculant (Lactobacillus plantarum VTT E-78076, E76) on the fermentation quality of wilted silage was studied. Furthermore, the possibility to improve aerobic stability of silages by combining an inoculant and chemical preservatives was investigated. Two experiments were conducted with wilted timothy-meadow fescue herbage (dry matter 429 and 344 g kg-1) using six treatments. In experiment I, E76 (106 cfu g-1 fresh matter (FM)) was applied alone and in combination with sodium benzoate (0.3 g kg-1 grass FM) or low rate of formic acid (0.4 l t-1 FM). In experiment II, E76 and a commercial inoculant were applied alone and in combination with sodium benzoate. Untreated silage and formic acid (4 l t-1 FM)...

Ensiling as a method to preserve energy crops and to enhance the energy yields Organic Eprints
Jaakkola, Seija; Stoddard, Fred; Kymäläinen, Maritta; Maijala, Pekka; Viikari, Liisa.
Effects to ethanol: Storing with additives increased the yield of sugars in enzymatic hydrolysis. Water soluble sugars well preserved. Some cellulose hydrolysed during ensiling. Storing altered the structure of the substrate? Suffered from acid formation when no additives were supplied. Effects to methane: Storing with or without additives increased methane yield. Formed acids were utilized, as well as the preserved water soluble sugars. Prolonged storing seemed to decrease methane yields.
Tipo: Conference paper, poster, etc. Palavras-chave: Crop husbandry; Environmental aspects.
