Good afternoon, this is the fourth week that we post so our Winograndsky column is one month old! Do you want to know which are the results after one month cultivating bacterias? If so, keep reading.
In the surface we can observe bubbles (they don't dissapear). We think they're a result of aerobic bacterias breathing because they can receive oxygen easily due to they're in the surface. That's why last week we couldn't see any activity there, they didn't change their colour but they were breathing so that this week the results (oxygen produced) can be observed.
Then, around the big black spot there's still a white halo around it. In the dark part, there isn't any orange spot, because of the foil we used to protect that part from the sun light (the foil doesn't let the light hit the dark part). This way, these bacterias can't use carbon to thrive because they don't receive energy from the sun, so that orange areas are totally disappeared. We can deduct that sun light is totally related to nonsulfur bacterias.
We can see that the typical sand colour (brown) area takes up more space than last week. It means that aerobic bacterias keep working and they work slowly so that we can observe little changes every week.

Really serious winogradsky monitoring here! Excellent!!!!
