Proteins synthesized during the encystment of Azotobacter vinelandii were radiolabeled with [35S]methionine and analyzed by sodium dodecyl sulfate-polyacrylamide gel electrophoresis. Pulse labeling was used to demonstrate that early encystment-specif

Unique cyclic compounds were found in the lipid fraction of Azotobacter vinelandii cysts. In addition to two major molecular species which had already been identified, 5-n-alkylresorcinol and its galactoside derivative, five other molecular species (

Dormant cysts of Azotobacter vinelandii germinated at 30 degrees C in Burk nitrogen-free media containing 1% glucose. Samples taken at intervals and examined by electron microscopy revealed that as germination progressed, vesicle-like and fibrillar s

Unique lipids found in Azotobacter vinelandii cysts are derived primarily from beta-hydroxybutyrate used to induce encystment. Tracer studies with beta-[14C]hydroxybutyrate showed that the biosynthesis of these compounds during encystment began at 8

Encystment of Azotobacter vinelandii (ATCC 12837) in modified Burk nitrogen-free medium (pH 7.0) containing 0.2 percent beta-hydroxybutyrate occurs optimally in 0.37 to 0.44 mM solutions of calcium ions. Suspension of cells in media deficient in calc

Sporulating cells of Bacillus licheniformis excrete three seryl proteases that are of similar size, 28,000 daltons, but of different charge at pH 6. The peptide antibiotic bactracin is released from the cells at the same time and exists, in part, as

Azotobacter vinelandii was found to form novel lipid compounds when encystment was initiated by 0.2% beta-hydroxybutyrate. An examination of these compounds led to the isolation and characterization of 5-n-heneicosylresorcinol, 5-n-tricosylresorcinol

The properties of Azotobacter vinelandii deoxyribonucleic acid (DNA) and folded chromosomes were studied and compared to those of Escherichia coli as a standard. Based on melting temperature and buoyant density measurements, the guanosine + cytosine

The genetic mechanisms associated with ampicillin resistance in strains of Haemophilus influenzae type b were investigated. In experiments concerned with transfer of total deoxyribonucleic acid in vitro, expression of resistance by wild-type strains
