Abstract
1.
1. The isolation of fatty aldehydes (as 2,4-dinotrophenylhydrozones) from the bacterial fraction of rumen digesta is described.
2.
2. Mixed rumen bacteria are a rich source of aldehydrogenic lipid as indicated by an aldehyde/phosphorus ration of 0.19 in the non-dialyzable lipid, and the yielding of 2.2. g of aldehyde (calculated as pentadecanal) per 100 g of total bacterial lipid.
3.
3. The major bacterial aldehydes are palmitaldehyde and C15 branched-chain aldehydes.
4.
4. The aldehyde pattern of rumen bacteria is strikingly similar to the aldehyde patterns in certain ruminant lipids suggesting a possible origin of some ruminant aldehydes in the bacteria.
