Living together in biofilms: the microbial cell factory and its biotechnological implications
In nature, bacteria alternate between two modes of growth: a unicellular life phase, in which the cells are free-swimming (planktonic), and a multicellular life phase, in which the cells are sessile and live in a biofilm, that can be defined as surface-associated microbial heterogeneous structures comprising different populations of microorganisms surrounded by a self-produced matrix that allow...
متن کاملCHAPTER FOUR PROTEOME COMPARISON OF Pseudomonas aeruginosa PLANKTONIC, SURFACE INFLUENCED PLANKTONIC AND BIOFILM POPULATIONS BASED UPON COMPOSITE TWO-DIMENSIONAL ELECTROPHORESIS GELS
It has long been recognised that bacteria can switch from planktonic unicellular organisms to sessile multicellular communities known as biofilms (Costerton et al., 1987; 1995). The transition to surface-attached (biofilm) growth is known to result in diverse changes in gene expression, which causes the attaching cells to become phenotypically and metabolically distinct from their planktonic co...
متن کاملMolecular mechanisms of chlorhexidine tolerance in Burkholderia cenocepacia biofilms.
The high tolerance of biofilm-grown Burkholderia cepacia complex bacteria against antimicrobial agents presents considerable problems for the treatment of infected cystic fibrosis patients and the implementation of infection control guidelines. In the present study, we analyzed the tolerance of planktonic and sessile Burkholderia cenocepacia J2315 cultures and examined the transcriptional respo...
متن کاملSpecialized activities and expression differences for Clostridium thermocellum biofilm and planktonic cells
Clostridium (Ruminiclostridium) thermocellum is a model organism for its ability to deconstruct plant biomass and convert the cellulose into ethanol. The bacterium forms biofilms adherent to lignocellulosic feedstocks in a continuous cell-monolayer in order to efficiently break down and uptake cellulose hydrolysates. We developed a novel bioreactor design to generate separate sessile and plankt...
متن کاملDevelopment and Validation of a Chemostat Gut Model To Study Both Planktonic and Biofilm Modes of Growth of Clostridium difficile and Human Microbiota
The human gastrointestinal tract harbours a complex microbial community which exist in planktonic and sessile form. The degree to which composition and function of faecal and mucosal microbiota differ remains unclear. We describe the development and characterisation of an in vitro human gut model, which can be used to facilitate the formation and longitudinal analysis of mature mixed species bi...
