9th ASME International Conference on Radioactive Waste Management and Environmental Remediation: Volumes 1, 2, and 3.
In previous work the adsorption of a number of radioactive ions from solution by a strongly-magnetic iron sulfide material has been studied. The material was produced by sulfate-reducing bacteria in a novel bioreactor. The uptake is rapid and the loa

Growth of Streptococcus mutans Ingbritt on limiting sucrose in a chemostat at dilution rates of 0.05 to 0.4 h-1 (mean generation time, 14 to 1.7 h) resulted in a heterofermentative pattern of metabolic end products. During fast growth, lactic acid wa

SUMMARY: A strain of Pseudomonas fluorescens that had been isolated from a freshwater source on a plastic substratum was grown in continuous culture in minimal medium. The ‘adsubble’ process (adsorptive bubble separation process) was found to foa

Teichuronic acid was the major anionic polymer of Bacillus licheniformis NCIB 6346 durign phosphate-limited (P-limited) growth in the chemostat. This polymer was also present in significant quantities when B. licheniformis was grown under carbon-limi

Streptococcus mutans Ingbritt was grown anaerobically in a chemostat, at a rate (mean generation time, 13 h) similar to that in dental plaque, in a complex medium with excess glucose and at pH values of 6.5, 6.0, and 5.5. The yield of cells was const

Summary: Carbohydrate metabolism by the oral bacterium Streptococcus sanguis NCTC 7865 was studied using cells grown in a chemostat at pH 7.0 under glucose or amino acid limitation (glucose excess) over a range of growth rates (D = 0.05 h-1-0.4 h−1

When cells carrying the plasmids RP1, pDS4101 (a ColK derivative) or pDS1109 (a ColE1 derivative) were maintained in chemostat culture in the absence of antibiotic selection, plasmid-free segregants were not detected after 120 generations of nutrient

Oral streptococci transport sugars via the phosphoenolpyruvate-phosphotransfer-ase (PEP-PTS) system. In a specific assay of this system, low concentrations of chlorhexidine abolished the activity of the glucose and sucrose PTS in batch-grown cells of

Batch cultures of Streptococcus sanguis NCTC7865 were grown in complex medium in the presence and absence of the ionophores gramicidin, valinomycin and nigericin, to study their effects on growth and glycosyltransferase production. Growth of S. sangu
