In shaking culture, P. fluorescens can ensure adequate oxygen and nutrients, and also to prevent it from setting on the flask of the bottom, which will cause death due to lack of nutrients. Similarly, shaking prevents it clumps, thereby ensuring the P. fluorescens reproduction. On the contrary, heterogeneous environment is not adapted to P. fluorescens to survive due to the lack of oxygen, and it cannot help the medium to be almost equally distributed to the growing number of bacterial populations. Hence, if the flasks were sealed, it would decrease the bacteria proliferation efficiency.
