Angelo F. Carlucci of Scripps Institution of Oceangraphy prepares an "in situ unit" for launch, used to study bacterial activity in surface films. Photos at right are representative of observations obtained when the In Situ Unit is used. At top right is a microautoradiograph of metabolizing bacteria. The dark specks are silver grains exposed by tritium radiation from labeled organic substrates taken up by surface-film bacteria. At center right is an epifluorescence micrograph of bacteria stained with acridine orange that binds to the DNA in the bacteria (light flecks) and fluoresces when excited with blue light. This technique is used to enumerate bacteria. At bottom right is a scanning electronic micrograph of surface-film bacteria, magnification 8000x. 1981
