Cádiz, 1A- WINORANDSKY COLUMN, EIGHTH WEEK RESULTS

    This week our bottle has suffered an important change: big seaweeds have appeared!

    In general, the orange typical colour in the bottle has stayed. But the non-identificated ....on the surface last week has become into seaweeds.
    Then, on the bottom of the bottle, green bacterias have grown. These bacterias are sulphure depending photoautotrophic bacterias.
    The surface, where water is, is muddy because of aerobic bacterias.
