Field-Effect Biosensors Modified with Tobacco Mosaic Virus Nanotubes as Enzyme Nanocarrier

Proceedings, 2017
A new concept for the development of semiconductor field-effect biosensors by modification of a gate surface with tobacco mosaic virus (TMV) nanotubes, serving as enzyme nanocarrier, is presented.

Detection and Characterization of β-Lactam Resistance in Bacillus cereus PTCC 1015

The Scientific World Journal, 2004
In the present study, detection, isolation, and characterization of β-lactamases from Bacillus cereus PTCC 1015 were investigated. B. cereus was inoculated in nutrient broth containing ampicillin (50 μg.ml−1) for 24 h (35°C, 200 rpm).

Live to cheat another day: bacterial dormancy facilitates the social exploitation of beta-lactamases [PDF]

, 2015
The breakdown of antibiotics by β-lactamases may be cooperative, since resistant cells can detoxify their environment and facilitate the growth of susceptible neighbours. However, previous studies of this phenomenon have used artificial bacterial vectors
