INFLUENCE OF CHEMICAL AND PHYSICAL FACTORS ON BIOLOGICAL RESPONSES TO NEOMYCINS B AND C.
The two known components of the neomycin complex—neomycins B and C—have been shown to respond differently under the usual conditions of bioassay, and a critical analysis of existing methods and standards is recommended.

An essential protein component of acetyl CoA carboxylase, isolated and extensively purified from cell-free extracts of Escherichia coli, has been identified as malonyl CoA: d-biotin car boxyl transferase, indicating the presence of a biotin site on the carboxy transferase and catalyzing a slower abortive decarboxylation of malonyL CoA.
LIQUID NITROGEN FREEZING IN MICROBIOLOGICAL ASSAY SYSTEMS. I. PRESERVATION OF LACTOBACILLUS LEICHMANNII FOR DIRECT USE IN THE VITAMIN B12 ASSAY.
Suspensions of Lactobacillus leichmannii were stored in liquid nitrogen and were used as direct inocula in vitamin B(12) assays and showed good correlation between freshly prepared suspensions and frozen suspensions in basal medium stored 3 months.

The storage of Lactobacillus leichmannii in liquid nitrogen for direct use in the vitamin B12 assay was described by Sokolski, Stap)ert, and Ferrer and a different approach is described on treatment of data for stability of a test organism.
In vitro activity of actinospectacin in human whole blood.
In human whole blood, the in vitro activity compares favorably with chloramphenicol thus indicating that whole blood may predict in vivo activity better than the usual bacteriological media.
Effect of Wetting Agents on Permeability of Ochromonas danica
Evidence is presented that the synergisms were due to the effect of the detergents on the cell membrane, and that O. danica is more susceptible to changes in osmotic pressure by increasing concentrations of KCl.
