Interaction between biofilm development, structure and detachment in rotating annular reactors.

In biotechnology, composition of biofilms and suspended bioaggregates can be crucial for system performance or product quality. Consequently, understanding biofilm dynamics is important for any process optimisation. The aim of this study was to investigate biofilm development and detachment under different hydrodynamic conditions and varying glucose load.

Planktonic-cell yield of a pseudomonad biofilm.

Biofilm cells differ phenotypically from their free-floating counterparts. Differential growth rates in biofilms are often referred to, particularly in response to limited diffusion of oxygen and nutrients. We observed growth rates of attached Pseudomonas sp.
