Life in the Biofilm

[Don Schaeffer]

Much of the surface of the water in the mudpuddle culture has a gel-like consistency--not an easy flowing liquid. This is due to the mass of organisms and the process of digestion in the water. This is likely to remain until the nutrient in the film gets used up. Then the microbes will begin to die.
