“…The strongest evidence in favour of its identity with L-serine was obtained by microbiological assay with Lactobacillus helveticus and Leucono8toc me8enteroide8, both organisms having an absolute requirement for serine. When the degradation product was added to serine-deficient media it supported growth of both organisms to the same extent as did authentic serine when incorporated at the same concentration in a similar medium (Stokes & Gunness, 1945).…”

“…However, about 0.5 mmole of rhainnose is required for this degradation, and in one case (8) poor recoveries of activity were reported. The same infornlatioil call be readily obtained by oxidation of rhainnitol, using the procedure of Nicolet and Shinn (23), and only about 0.12 mmole of sugar is required.…”

“…Excess borohydride was destroyed after 12 hours by the addition of 2 N sulphuric acid. The rhamnitol was oxidized by the procedure developed by Nicolet and Shinn (23). Phosphate buffer a t pH 8 (10 ml) was added to the solutio~l together with glycine (200 mg) and 0.3 M sodium metaperiodate (1.5 1111).…”

Azotobacter indicil~iz was grown on ~nedia which contained D -g l~~~~e -l -c " ,The radioactive polysaccharides produced were hydrolyzed and the specific activities of the isolated D-glucose and L-rhamnose were measured. The sugars were degraded and the distribution of activity in the individual carbon atoms was determined.The results suggest that some L-rharnnose is formed froin D-glucose by a pathway which involves the breakdown of the glucose carbon slceleton.

The scaly outer layer of wool fibers is commonly believed to protect them from injury and to assist in the felting process. Little is known about the composition of this layer because no ready means of separating it from the rest of the fiber has been available. Earlier work in this laboratory has shown that wool that has been reduced with thioglycolic acid and then alky lated with ethyl bromide is attacked by pepsin in such a, way that the scale material remains intact while the in terior of the fiber is completely dis solved. The composition of the scale material so obtained has now been studied. It has been found that it is essentially protein in nature and, al though it contains the same amino acids as the whole wool, the proportions of these in the two materials differ.
