        Sumbawa honey is one of the best honeys in Indonesia. It has become trade mark of Sumbawa and also the main source of income for people of Sumbawa. According to National Standard of Indonesian, honey quality determined based on the quantity of glucose level in the honey. The honey control quality on farmer level was done based on the physical appearance which is not suitable with the industrial standard. Laboratory based on chemical analysis giving the best result measurement but either time or money consuming, it also gives difficulties for the farmer to use. Our team goal was to accommodate the necessity of glucose monitoring level of the Sumbawa honey by create a simple method and device which could be easily applied in the farmer level. <br><br>

         ECONEY is a genetic engineering of E.coli plasmid with capability to detect different level of glucose concentration in Sumbawa honey by emitting light as the expression of RFP protein, when it placed in the environment contains wide range of glucose. The color expression measurement then transform into smart mobile phone application in order to ease people in measuring glucose level of honey. The color expression of RFP in several dilution of Sumbawa honey used as the standard. In the future ECONEY are expected to become the device that can measure the authenticity of Sumbawa honey.

Project Description

Bba_J04450 has a lac promoter and mRFP gene, thus E Colli harboring this plasmid will give red color when the bacteria were grown with lactose or IPTG. Oppositely the expression of mRFP will be decreased when glucose was present in medium through a mechanism called catabolite repression. We use this phenomenon to measure the concentration of glucose in honey by calibrating the color of E Coli medium using android based mobile phone. Creation of novel circuit which consists of constitutive promoter followed by either Adenylate Cyclase or IIA GLC may place downward lac-mRFP circuit which could affect the sensitivity of catabolite repression. We expect an engineered E coli shows red color expression in different range of glucose concentration which can be used to measure the concentration of glucose in honey. By changing mRFP gene with amilCP, a blue fluorescent protein, we may obtain E coli expressing either red or blue color when different honey added to the medium.
