摘要：

Dissolved oxygen profiles were measured above and within a bacterial slime mass under a continuous flow of nutrient. The microprobe tip was 1.5 μ in diameter and its location, with respect to the slime-water interface, was known to = 2 μ. With dilute media, the respiration was substrate limited and high concentrations of oxygen were found throughout the slime mass. More concentrated media increased utilization so that oxygen concentrations approached zero in the depth of the slime. © 1969, American Chemical Society. All rights reserved.
