A New Perspective on Microbes Formerly Known as Nitrite-Oxidizing Bacteria

Nitrate reduction to nitrite, a possible source of nitrite for growth of nitrite-oxidizing bacteria.

Growth yields and other parameters characterizing the kinetics of growth of nitrite-oxidizing bacteria are presented. These parameters were measured during laboratory enrichments of soil samples with added nitrite. They were then used to reanalyze data for nitrite oxidizer growth in a previously reported field study (M. G. Volz, L. W. Belser, M. S. Ardakani, and A. D. McLaren, J. Environ. Qual....

Hydrogen Oxidizing Bacteria as Poly(hydroxybutyrate) Producers

Batch culture of Ralstonia eutropha using the recycled gas closed circuit culture system was conducted in order to develop a practical fermentation system for industrial autotrophic culture for poly (hydroxybutrate) production. The gas phase of the culture system consisted of substrate gas so that gases in this culture could be recycled as long as the amount of the gas consumed would be repleni...

The Discipline Formerly Known as Mir

Our exploration is not a science-fiction essay. We do not try to imagine how music will be conceptualized, experienced and mediated by our yet-to-come research, technological achievements and music gizmos. Alternatively, we reflect on how the discipline should evolve to become consolidated as such, in order it may get an effective future instead of becoming, after a promising start, just a “wou...

Hunner Lesion (formerly Known as Hunner’s Ulcer)

History Guy Leroy Hunner, a Boston gynaecologist, described this inflammatory bladder disease a century ago in great detail for the first time in a series of papers, the first being published in 1914 (republished in 1915). In this first paper he writes: “While cystoscopy usually reveals only one inflammatory spot, there may be two or three granulation areas near together or somewhat separated, ...
