- Title
Development of a Biosensor Device for Detection of Several Metals Simultaneously
- Abstract
Assembling parts for developing microbial biosensors for detection of toxic metals and for organic compounds.
- Introduction
There exists two essential needs which enabled us to design the trimetallic probe. The need for alternative forms of oil, in fact their methods and the bioremediation of metals ions from the environment.
Micrococcus luteus strain (ATCC 4698) was transformed by plasmid pUC57-S-3M, in which Fe (II), Ni (II) and V (II) were fused to the fluorescence proteins (ECFP, EYFP, and mRFP respectively and to a fluorescent protein coding region [C0061(lux I)] ligated with a signaling sequence BBa_I13207.
The pUC57-S-3M was standardized for its specific sensoribility response to three metal ions and to sulfur (S), in order to detect metal contamination and/or hydrocarbons associated to these metals. Single and combination of the tree metals were used at different concentrations (0.2, 2, 50 ppm). The pUC57-S-3M was grown in the presence and absence of oxygen and/or hydrocarbon (Thiophenol). Only results from combined metals are reported. The biosensoribility was determined by the response of the pUC57-S-3M to the different concentrations of the metals. This response was measured by bioluminescence, fluorescence, DNA concentration, bacterial growth. These parameters were related to sensoribility of the pUC57-S-3M.
- Objective
Develop and standardize microbial biosensors that respond specifically to toxic metals (nickel, vanadium, iron) simultaneously at different concentrations.
- Project Implementation
Combine parts such as lux and lacZ gene reporters with inducible promoter and flourescent proteins to develop a microorganism (chasis) with the functions of detecting the toxic metals and or organic compounds.
