Kinetic studies of the transport of aromatic amino acids by Pseudomonas aeruginosa revealed the existence of two high-affinity transport systems which recognized the three aromatic amino acids. From competition data and studies on the exchange of preformed aromatic amino acid pools, the first transport system was found to be functional with phenylalanine,(More)

Bacteriol. 92:851-855. 1966.-The changes occurring in Pseudomonas aeruginosa during phosphate starvation in a phosphate-deficient medium were assessed by measuring(More)
Resting-cell suspensions of Clostridium perfringens actively transported glucose and mannose but not six other carbohydrates which would support at least limited growth of the microorganism. Competition studies suggested that glucose and mannose were transported by a common mechanism which was highly specific. Analyses of intracellular pools demonstrated(More)
Properties of the transport systems for amino acids in Pseudomonas aeruginosa were investigated. Exogenous (14)C-labeled amino acids were shown to equilibrate with the internal native amino acid pool prior to incorporation into protein. When added at low external concentrations, the majority of the amino acids examined entered the protein of the cell(More)
The accumulation and behavior of various amino acids in the pool of Pseudomonas aeruginosa (ATCC 9027) were investigated. Patterns of pool formation and maintenance varied with different amino acids tested and were dependent, to a considerable extent, upon the ability of the organism to catabolize the particular amino acid. The establishment of steady-state(More)
Traceability in the sawmilling industry is a concept that, among other benefits, could be used to more effectively control and pinpoint errors in the production process. The fingerprint approach is a traceability concept that in earlier studies has shown good potential for tracing logs between the log sorting .station and the saw intake. In these studies.,(More)

Bacteriol. 90:1-7. 1965.-From sedimentation analyses it was found that the ribosomal content of Pseudomonas aeruginosa decreased during endogenous respiration. A(More)
Pseudomonas aeruginosa was shown to utilize the majority of commonly occurring amino acids for growth as either the sole carbon or the sole nitrogen source. During carbon or nitrogen deprivation, the rates of transport of most of the amino acids remained unchanged; however, the transport rates for glutamate, alanine, and glycine increased under these(More)
