TLDR
By the staining of soil with the fluorescent dye acridinorange and examination of the stained soil under the fluorescence microscope, it is possible to observe directly the living bacteria of soil in their autochthonic condition.Abstract:

Simplified procedures for releasing and concentrating microorganisms from soil for transmission electron microscopy viewing as thin-sectioned and frozen-etched preparations.
TL;DR: Freeze-etching showed that the cell types and size distributions for cells which have been released and concentrated from soil are in general agreement with those for cells in a crude soil slurry in which no attempt to release and concentrate cells was made.

The effect of caffeine on cell growth and metabolism of thymidine in Escherichia coli.
TL;DR: It is suggested that caffeine interferes with uptake ofThymidine, conversion of thymidine to dTTP and the DNA synthesis process itself, and could be the result of the inhibition of DNA synthesis.

Microorganisms in unamended soil as observed by various forms of microscopy and staining.
TL;DR: C Capsule-like areas were noted surrounding many of the resident microbial cells of soil when viewed by the various forms of bright-field microscopy and it was concluded that these areas are not capsules but may represent a structural component of nonmultiplying microbial cells in soil.
Bacteria in intertidal sediments: Factors rclatcd to their distribution1
TL;DR: Mann et al. as mentioned in this paper found that the distribution of deposit-feeding invcrtcbratcs is closely correlated with the bacterial content of sediments, and that grain size alone accounts for over 80% of the variance in bacterial numbers.
