Abstract: Abstract Bioconvection is a fascinating pattern forming phenomenon driven by the swimming activity of microbes. There is a common belief that bioconvection has a positive effect on the whole microbial population by aerating deep layers in the suspension. In order to detect such a biological benefit, we performed experiments with several strains of Bacillus subtilis and Bacillus licheniformis of different swimming capabilities. Bioconvection is a robust phenomenon, we observed it at numerous strains in different growth phases. Nevertheless data evaluation has not revealed a similarly robust positive effect on population growth.
