Biofilm Assays on Fibrinogen-coated Silicone Catheters and 96-well Polystyrene Plates
Authors:  Cristina Colomer-Winter, José A. Lemos and Ana L. Flores-Mireles, date: 03/20/2019, view: 3151, Q&A: 0
Biofilm formation is a well-known bacterial strategy that protects cells from hostile environments. During infection, bacteria found in a biofilm community are less sensitive to antibiotics and to the immune response, often allowing them to colonize ...

Experimental Setup for a Diffusion Bioreactor to Isolate Unculturable Soil Bacteria
Authors:  Dhiraj Kumar Chaudhary and Jaisoo Kim, date: 10/05/2019, view: 2060, Q&A: 0
Unculturable bacteria are those bacteria which proliferate in their native habitat but unable to grow or thrive in the normal laboratory media and conditions. The molecular techniques have revealed the significance of these uncultured bacteria in ...
