Oligotrophy, or the inability of bacterial cells to propagate at elevated nutrient concentrations,
is a controversial phenomenon in microbiology. The exact cause of the unculturability of …

The regulation of lactic acid production, the regulation of lactate fermentation and the role of
lactate as intermediate in the rumen metabolism was studied. The pH had a pronounced …

Indigenous heterotrophic marine bacteria are of great importance to global nutrient cycling.
Predominant native bacteria are of ultramicrobacterial dimensions, are not associated with …

Since Megasphaera elsdenii ferments a variable part of dl-lactate to butyrate, measurement
of the percentage of dl-lactate fermented to propionate via the acrylate pathway in rumen …

Marine bacteria in Resurrection Bay near Seward, Alaska, and in the central North Sea off
the Dutch coast were cultured in filtered autoclaved seawater following dilution to extinction. …

The presence of methanogens Methanobacterium arboriphilus, Methanobacterium bryantii,
or Methanobrevibacter smithii increased the level of cellulose fermentation by 5 to 10% in …

The sulfur cycle in a microbial mat was studied by determining viable counts of sulfate-reducing
bacteria, chemolithoautotrophic sulfur bacteria and anoxygenic phototrophic bacteria. All …

Methane production in pure cultures ofMethanobacterium ruminantium andMethanobacterium
MoH strains is inhibited by halogenated methane analogues in Μm concentrations and by …

Nutritionally physiological patterns of Pseudallescheria boydii (Microascaceae) and the
