Application of stereolithographic custom models for studying the impact of biofilms and mineral precipitation on fluid flow

Article Abstract:

The application of stereolithographic models and the integration of three-dimensional lattice Boltzmann simulations to microbiological studies are reported. Several models with a variety of internal configurations are designed, fabricated and used to examine the impact of biomass accumulation and microbially induced calcite precipitation on fluid flow.

Autoinducer 2 affects biofilm formation by Bacillus cereus

Article Abstract:

Cell-free supernatants from growing Bacillus cereus strain ATCC 10987 induced luminescence in a Photorhabdus luminescens (delta)luxS mutant, indicating the production of functional auto inducer 2(AI-2). It was observed that AI-2 had an inhibitory effect on biofilm formation by B. cereus and promoted release of the cells from a performed biofilm.
