Jan 01, 2018Jan 01, 2018Johnson et al. (2005) have previously demonstrated that vacuum packing constitutes a reliable and accurate model system for laboratory-scale silage. The vacuum-packed bags were then sealed by a "Golden star" chamber vacuum packaging machine to remove oxygen, and stored in a dark room at 15 C. Get price

Vacuum packing: a model system for laboratory‐scale silage
Nov 01, 2004Aims: To determine the utility of vacuum-packed polythene bags as a convenient, flexible and cost-effective alternative to fixed volume glass vessels for lab-scale silage studies. Methods and Results: Using perennial ryegrass or red clover forage, similar fermentations (as assessed by pH measurement) occurred in glass tube and vacuum-packed silos over a 35-day period. Get price
Variations in bacterial communities in laboratory‐scale
Silage was also prepared in vacuum-packed plastic pouches to examine differences between laboratory-scale and farm-scale silos. Variations were determined by fermentation products, colony counts and denaturing gradient gel electrophoresis (DGGE) profiles, and a cluster analysis was made to enable grouping and qualitative differentiation.

Vacuum packing: a model system for laboratory
Conclusions: Vacuum-packed silos do provide a realistic model system for lab-scale silage fermentations. Significance and Impact of the Study: Use of vacuum-packed silos holds potential for lab-scale evaluations of silage fermentations, allowing higher throughput of samples, more consistent packing as well as the possibility of investigating Get price

Vacuum packing: a model system for laboratory
Significant differences in pH decline and lactate accumulation were observed at different vacuum settings. Gas accumulation was apparent within all bags and changes in bag volume with time was observed to vary according to initial packing density.
