A temperature-compensated ultradian clock ticks in Schizosaccharomyces pombe
Article Abstract:
A temperature-compensated ultradian oscillation in Schizosaccharomyces pombe shows the characteristics of a cellular clock and this ultradian clock is believed to control the process of cell division. At constant temperature, the ultradian rhythm is maintained for 20 hours without fail. S. pombe may be an ideal organism for dissecting and understanding the genetic and molecular structures of clock mechanisms in cells. The influence of light on cell clocks was tested and was shown to be minimal.

The microaerophilic flagellate Giardia intestinalis: Allium sativum (garlic) is an effective antigiardial
Article Abstract:
Research has been conducted on whole garlic extract. The authors report that they have investigated this extract and some of its components for antigiardial activity, and they demonstrate that whole garlic and allyl alcohol collapse transmembrane electrochemical membrane potential of microaerophilic flagellate Giardia intestinalis, and that the surface topography and internal architecture of G. intestinalis have changed during incubation with biocides.

Too much O2?
Article Abstract:
Microorganisms have varying sensitivities to oxygen. Strictly anaerobic microorganisms are grown without oxygen while microaerophilic organisms can survive with minimal oxygen. Microbiologists have to be careful when culturing microorganisms that may be microaerophilic because once removed from their natural habitat, the protection from the herd is removed and the ambient oxygen saturation is altered.
