Microscopic examination of natural sessile bacterial populations from an alpine stream
Abstract
Natural populations of bacteria associated with the slime on submerged surfaces in a mountain stream were examined by phase-contrast and electron microscopy. The slime contained large numbers of bacteria which were predominantly gram-negative as determined by their cell wall structure. Examination of the in situ distribution of cells revealed that they were enmeshed in an extensive fibrous matrix whose component fibrils were stained with ruthenium red. The arrangement of slime fibrils immediately around individual bacterial cells suggested that this material was produced by these bacteria. This slime facilitated microcolony development and also anchored the bacteria to a particular surface. It is proposed that these slime-enmeshed microcolonies constitute functional communities within which most sessile bacteria live.

About these checks
Registry, retraction, Cites and statistics results are computed, not judged, with one exception: a printed reference that no index lists is read once by a model before it counts as a citation error. Claims are extracted by a model and kept only when their quote appears verbatim in the text; each cited source is then checked, with a model’s help, for whether it says what the claim relies on. Those verdicts can be wrong — read the claim’s quote and the cited source before relying on one.
Statistics and arithmetic are recomputed, not judged.
Confidence bands are shown only for fields calibrated on our annotated test set. None is calibrated yet, so no band is shown.
