11.22.11 Winogradsky Column Observations- Thanksgiving Edition!














11/22/11

top view: all columns dark green, bottom occlusion is darker on top (richer phototrophic layer)


control: purple patches near bottom layer (purple s development)

no green s development yet

middle occlusion: no purple patches near bottom layer (devt of purple s layer not happening) bottom layer looks gray and drab, anaerobic sediment  weak or not developing


top: dirt layer rich and dark, purple patches developing well (purple s), rust layer larger than others

bottom occlusion: no rust colored layer (rest have it, what does this suggest) deep purple layer larger than rest (strong purple non s devt?), anaerobic layer covered but purple patches coming in near bottom (purple s).
