| the structure of anaerobic bacterial communities in the hypolimnia of several michigan lakes. | the structure of bacterial communities, the distribution of sulfide and oxygen, bacteriochlorophyll concentrations, and the temperature profile were determined for the anaerobic hypolimnia of two lakes in southern michigan. information from these studies, plus qualitative observations of two other lakes and two ponds over a 4-year period were used to correlate the spatial distribution of the populations, cell size, arrangement of photosynthetic vesicles or lamellae, presence of gas vacuoles or ... | 1975 | 1090351 |
| a morphological study of anaerobic bacteria from the hypolimnia of two michigan lakes. | dense populations of anaerobic bacteria were found sequentially layered below the thermocline in two eutrophic lakes in southwest michigan. phase and electron microscopy of whole cells and thin sections were used to reveal the in situ morphology of the dominant members of the community. the predominant chlorophyll-containing bacteria were identified on the basis of their morphology to be members of the genera pelodictyon, prosthecochloris, clathrochloris, chlorochromatium, pelochromatium, thiope ... | 1975 | 1090350 |
