Abstract:		"Invasion rates of airborne organic substances into sterile mineral medium were compared by using flasks closed with cotton stoppers, silicone stoppers, and screw caps with Teflon gaskets. The resulting increases of dissolved organic carbon were 0.5, 0.2, and 0 mg/liter per week, respectively. The compounds supported the growth of lake water bacteria and a strain of Pseudomonas fluorescens. Growth rates were correlated to the permeability of the stoppers used. The measured input of organic carbon in the sterile mineral medium is considered to be a minimum value for the actual contribution of organic compounds by the air. Multiplication rates of the bacteria suggest that the organisms prevent the escape of volatile organic substances from the medium by rapid utilization. The steady nutrient supply through the air should be considered in growth experiments with bacteria at low concentrations of nutrients"
