Experiments with Pine and Spruce

The survival of two hygienically relevant bacteria, Escherichia coli pIE636 (E. coli) and Enterococcus faecium (E. faecium) was followed on wooden sawdust of seven different European woods (pine, spruce, larch, beech, maple, poplar and oak)…

In the experiments with pine and spruce, pine performed better than spruce… A dramatic reduction in bacterial numbers of E. coli was detected on pine and oak… After 24 hours, no cultural bacteria could be detected on pine… A drastic decrease of the E. faecium titre was observed on pine, oak and spruce… After 24 hours… no cultural bacteria could be obtained from these woods…
